When equipped with UConnect, the navigation radio becomes compatible with the hands-free module within the system. This feature enables the user to place voice-activated, hands-free calls to “Points of Interests” such as restaurants, banks, or other public addresses located within the navigation system’s information database. Phone numbers and call times appear on the system’s screen upon incoming calls.
The navigation radio for the 2005-2007 Grand Cherokees is housed in the upper center section of the dashboard. Features include a large 5.8-inch full-color display, MP3 player, AM/FM stereo, six-disc CD system and navigation system in one unit. An eight-way joystick allows the user to scroll through the navigation menus and icons quickly and effortlessly.
The system guides the user through the drive route providing voice commands, mile by mile, turn-by-turn until the final destination is reached. Destinations may be entered into the system 10 different ways and the screen may be viewed as a detailed map or enlarged to be viewed turn-by-turn.
With MP3 capability and the option to add various entertainment and communication features, the navigation system is clearly in the forefront of information and entertainment technology. The system effectively calculates the quickest and most accurate route and immediately redirects the driver should he or she veer off path.
The MP3 player is a navigation first, and the radio also features SIRIUS Satellite Radio availability. The MP3 feature enables the user to view and play files and folders contained within MP3 discs. Coupled with SIRIUS Satellite Radio, the stream listing, stream category, song title, and artist can be viewed on the system’s display screen.
The navigation system features a single DVD disc which contains mapping, points of interest and business phone numbers across the U.S. (where digitized mapping data and information are available). In addition, route calculations may be made quickly with Alpine’s proprietary software algorithms which provide routing information within 10 seconds. This is crucial when a driver misses a turn and needs an immediate re-route.
The navigation system receives its GPS, or global positioning system signals, from up to eight satellites to display the position and direction of the vehicle. A gyroscope and the vehicle’s speed sensor enable the system to display the present vehicle position even in locations where a GPS signal may not be available. When a destination is entered, the navigation system uses data from the DVD to quickly calculate a route.

REC Nav radio FAQ:
To remove the navigation disc cover, a special tab must be pushed downward
How do I load the Navigation disc?
The navigation disc loads into the lower tray on the REC radio. A special tab needs to be pushed downward and pried outward to release the cover. The tab is located on the left side of the DVD tray, as shown in the photo above.
Can I use the navigation software in my computer?
No. This proprietary software is devoted exclusively by Alpine for the sole purpose of navigation.
Can I play movies or other DVD type discs?
No. The REC is designed to only read the special DVD-ROM Navigation disc. A few different aftermarket companies provide a modification that adds video/audio input jacks, allowing the use of an external device like a DVD player. Also available are external input adaptors for hooking up external audio devices such as the Apple iPod’s.
Which audio CD formats are supported?
CD, most CD-R (recordable CDs), most CD-RW (rewritable CDs) and MP3 CD discs.
Will the radio or CD still play while using the Navigation functions? Yes, you can play the radio or CDs from the built-in CD changer while in the Navigation mode.
Does the REC have its own speaker?
No, it works through the vehicle sound systems left front speaker. During voice commands the radio is automatically muted. The volume for the voice commands can be raised or lowered independent of the radio volume, but only during a voice command.
What are the “RDS” and “PTY” radio features?
RDS stands for “Radio Data System”, a service provided by FM Radio Stations. In addition to the conventional music and voice contribution, information is transmitted in the form of encoded digital signals that are decoded by any RDS compatible car radio (or home radio to a limited degree). A radio station must have the appropriate hardware and software installed to support RDS.
PTY is part of the RDS function and stands for “Program Type”, a feature allows you to search for stations by type of category (i.e. country, classical, rock, news). When ‘PTY’ is selected and you press the ENTER key, the current category is displayed. Pressing the SEEK button tunes the unit to the next station that broadcasts the chosen program type. Pressing the SCAN button searches the unit for all music categories. Not all radio stations broadcast the PTY signal.
The USA supports RDS at a lower level (station name and type only) while the vast majority of FM Stations throughout Europe and Britain feature Dynamic RDS, a more advanced system that includes traffic announcements and other features. RDS data can also be used to transmit the current time and date, as set by the radio station. A clock on an RDS radio never has to be adjusted and will automatically set itself for daylight saving time.
How do I clean the screen?
The screen should be cleaned with a soft dry cloth. A high-quality camera lens cloth works best for this, available at any camera store. No liquids should ever be used to clean the screen.
Can I install the REC radio in a 1999-2004 model Grand Cherokee (WJ)?
No. The REC uses the new CAN Bus data system and is not compatible with the PCI system used in pre-2005 models of the Grand Cherokee.
Can I install the REC radio in a 2005-up export model Grand Cherokee (WH)?
No. The REC navigation radio is only compatible with vehicles built for the North American market. Europe and other countries use a similar radio, model REJ.
Can I use the REJ European navigation DVD disc in my REC radio?
No. North American REC models must use the North American DVD disc, and REJ export models must use the DVD discs made for export markets.
My 2005-up Grand Cherokee did not come with the navigation radio, can I add one?
Yes. This is a very easy upgrade. See the Navigation radio upgrade / installation section below.
Should I buy a new or used navigation off of eBay or other online source?
Good deals can be found on navigation radios sold online but buyers must be aware of a few issues. See the “Buying tips” at the end of the Navigation kits and parts table belo
Notes On Playing MP3 Files:
The NAV radio can play MP3 files, however, acceptable MP3 file recording media and formats are limited. When writing MP3 files, pay attention to the following restrictions.
Supported Media (Disc Types)
The MP3 file recording media supported by the radio are CD-ROM, CD-R and CD-RW.
Supported Medium Formats (File Systems)
The medium formats supported by the radio are ISO 9660 Level 1 and Level 2 and includes the Joliet extension. When reading discs recorded using formats other than ISO 9660 Level 1 and Level 2, the radio may fail to read files properly and may be unable to play the file normally. UDF and Apple HFS formats are not supported.
The radio uses the following limits for file systems:
– Maximum number of directory levels: 15
– Maximum number of files: 255
– Maximum number of folders: 100
– Maximum number of characters in file/folder names:
– Level 1: 12 (including a separator “.” and a 3-character extension)
– Level 2: 31 (including a separator “.” and a 3-character extension)
Multisession disc formats are supported by the radio. Multisession discs may contain combinations of normal CD audio tracks and computer files (including MP3 files). Discs created with an option such as “keep disc open after writing” are most likely multisession discs. The use of multisession for CD audio or MP3 playback may result in longer disc loading times.
Supported MP3 File Formats
The radio will recognize only files with the *.mp3 extension as MP3 files. Non-MP3 files named with the *.mp3 extension may cause playback problems. The radio is designed to recognize the file as an invalid MP3 and will not play the file.
When using the MP3 encoder to compress audio data to an MP3 file, the bit rate and sampling frequencies in the following table are supported. In addition, variable bit rates (VBR) are also supported. The majority of MP3 files use a 44.1 kHz sampling rate and a 192, 160, 128, 96 or VBR bit rates.
ID3 Tag information for artist, song title and album title are supported for version 1 ID3 tags. ID3 version 2 is not supported by the radios.
Playlist files are not supported. MP3 Pro files are not supported.
Playback of MP3 Files
When a medium containing MP3 data is loaded, the radio checks all files on the medium. If the medium contains a lot of folders or files, the radio will take more time to start playing the MP3 files.
Loading times for playback of MP3 files may be affected by the following:
Media – CD-RW media may take longer to load than CD-R media
Medium formats – Multisession discs may take longer to load than non-multisession discs
Number of files and folders – Loading times will increase with more files and folders
To increase the speed of disc loading, it is recommended to use CD-R media and single-session discs. To create a single-session disc, enable the Disc at Once option before writing to the disc.

REC Navigation kits and parts
For most 2005-2007 model Chrysler, Dodge and Jeep vehicles
The REC Navigation Radio combines a 5.8-inch full-color display, AM/FM Stereo Radio, Six-disc CD/MP3 player and navigation system that utilizes DVD technology, all in one handy unit. This sophisticated, yet simple-to-use navigation system guides you to your precise destination through the use of Global Positioning System (GPS) satellite technology and an onboard computer. The system offers turn-byturn route guidance with voice instruction, automatic re-route calculation, unique smart-spelling feature, extensive listings for points of interest and enough memory to store 100 personal addresses. Unit includes a geographic DVD with routing directions for the continental 48 States and parts of Canada. The radio features 12 AM, 12 FM, and 12 Sirius Satellite Radio pre-sets. This system is Sirius Satellite Radio capable and displays station names, song title and artist. To obtain Sirius Satellite Radio, a satellite receiver/antenna kit and subscription to the Sirius service is required.
About part numbers: Model codes and part numbers for radios and discs can be quite confusing. A 3-letter model code is assigned for each radio in a particular series. Within that model code, “REC” for example, many different part numbers are assigned during the production run and sales life. Most part numbers start out with a series of numbers, such as “56038646”. Revisions after that add a 2-letter suffix, as in “56038646AA” followed by “AB”, “AC” “AD” and so on. Revisions can consist of circuitry updates or changes, firmware fixes and changes, and minor cosmetic changes. In addition, sometimes changing a supplier for a particular part will result in a updated part number. In most cases the higher the last letter of the part number the newer the part.
A major change in a part will usually result in the numbers being totally changed. For example, one of the later 2006 model REC radios has a part number of ” 56038646AM”. 2007 models started with a totally different number, “5064184xx”. In this case, the 2007 models have an added jack and circuitry to accomodate the rear back up camera and therefore the entire number was changed.
Interchangeability: From what we have seen, all of the “REC” radio part numbers below are interchangeable with all 2005-2007 Chrysler, Dodge and Jeep vehicles that have the newer CAN bus. The radio reconizes which vehicle it is in and will display the opening screen logo accordingly for either “Dodge”, “Chrysler” or “Jeep”.
Part # (sorted oldest to newest)
REC navigation radio – Radio onlyNote for 2005-2006 model radios: “56038646AM” is the revised unit with an “improved” joystick. Prior models have had problems with the joystick breaking. All 2007-up models have the improved joystick, although there has also been a few reports of the newer joysticks breaking. Replacement joysticks are available from aftermarket companies for around $10-$15. Installtion requires minor disassembly of the radio and some soldering.
All 2007 model radios include a 3-pin rear camera input jack on the rear of the radio. Very late build 2006 models may also come with the camera jack.
The prices listed for navigation radios represent dealer parts and accessories pricing. The price for a factory installed navigation radio is typically less than these prices. The factory price for the same type of radio may vary between vehicles due to the inclusion of different associated components (speakers, rear camera, for example) and also for marketing reasons. Radios are often quickly discontinued and only the newest revisions may be available from Chrysler, Dodge and Jeep dealers.
Important: Early model radios (P/N 56038646AI through P/N 56038646AL) cannot be used with 2005-up base model Grand Cherokees (vehicles without premium sound). Radios will have garbled sound for the navigation voice.
REC navigation radio – Kit package(includes NAV radio, GPS antenna and DVD-ROM geographic disc covering all of the United States and parts of Canada.)
2005-2006 models Note: P/N 82208653AE and later packages include nav radio P/N 56038646AM. “AM” is the revised unit with an improved joystick. Prior models have had problems with the joystick breaking, although there has also been a few reports of the newer joysticks breaking.

Tips on buying a new or used navigation unit online from eBay
or from non-authorized dealers
If you are buying a navigation unit online from a non-authorized dealer note that you will NOT have a factory warranty. It is important to buy from a trusted source with excellent references, some of which offer their own warranty. Be sure that in addition to the radio that you receive the correct navigation antenna, latest navigation disc and preferably the owner’s manual. There have been a noticeable amount of problems with the joystick controls breaking on REC navigation radios. This is due to a design flaw that was fixed on radios built after mid-September 2005. Joysticks have also been damaged in shipping due to poor packing by those selling used units, which rarely come in their original factory packaging. Assure that the seller will provide a non-DOA or longer guarantee, and that the unit will be carefully packaged.
Navigation radio upgrade / installation
REC Navigation radio shown in a 2005 WK Rocky Mountain edition
Upgrading from a factory standard radio to the navigation radio is easy as far as the installation goes. A bezel kit is required, as shown in the parts list above. The kit includes a new center bezel, attaching bracket, navigation face plate, left & right AC outlets and 5 mounting clips.
Factory radio removal:
Radio/vent bezel removal
Standard radio mounting
Front and back views of the navigation radio bezel
1. Disconnect the battery negative ground cable.
2. The one-piece radio/vent bezel is fastened with 5 spring clips and aligned at the top with plastic tabs. Grab the bezel in the back curved area and pull it forward to pull it away from the plastic tabs. Carefully pull the bezel outwards around its perimeter to release it from the spring tabs.
Rear connectors ’05-’06
Rear connectors 2007
3. The radio is fastened with four screws, remove them and carefully pull the radio out enough to access the rear connectors. It is important to note that the radio antenna connector is the newer “locking” style”. Grasp the outer ring and pull outward to release the antenna from the radio. For reinstallation it simply pushes back on and locks in place.
Navigation antenna locations
4. Install the navigation antenna. On WK models the factory GPS antenna is located behind the radio and attached with two screws. The antenna may also be positioned on top of the instrument cluster, under the bezel that surrounds the speedometer/tach, and attached with double-sided foam tape.
5. Install the new navigation radio, plugging in the nav antenna, the radio antenna, and the 22-pin radio connector. Carefully push the radio into place making sure no wires are causing any binding. Install the 4 radio screws. Install the new bezel and radio trim plate.
Support brackets used for standard radios
Note: there are two metal bars that extend downward from the “framework” that runs along the dash, which supports the radio and holds it in place (see image above). If you are upgrading to the REC, the two metal bars must be removed in order for the REC to be installed, otherwise there will not be enough clearance.
6. Reconnect the battery negative ground cable.
7. Turn the ignition on and power up the radio. Install the navigation disc by first removing the navigation disc door. A special tab on the door must be pushed in to release it, as shown in the photo below. Install the disc and replace the door. The navigation system will now load the disc and the menu display will come up.

REJ navigation radio
(For 2005-2006 “WH” export models only, not compatible with North American REC navigation discs)
The all-new 2005 Grand Cherokee export models (“WH”) began production in March of 2005. The optional navigation radio is similar to the “REC” model that is being offered in the North American market WK Grand Cherokees. Both models feature a 5.8-inch full-color display, MP3 playback capabilty, AM/FM stereo and six-disc CD system.
The North American (REC) and export (REJ) navigation database discs are not interchangeable. If a North American vehicle is exported to Europe (or other export markets) the REC model radio must be exchanged for a REJ model radio in order to utilize the export navigation maps as well as the radio stations.
The DVD included with the REJ radios features mapping for the following regions:
Western Europe Region Group
RHD Asia Region Group
Central Eastern Europe Region Group
Middle East Region Group
Central America Region Group
Puerto Rico Region Group
