Jeep Grand Cherokee WJ - Factory navigation system

Mopar & Jeep Navigation Systems

New for model year 2003: AM/FM/CD GPS Navigation Radio

Model RB1 4.9 inch screen

Jeep is introducing, as a Mopar accessory, this new in-dash AF/FM/CD/NAV system in November of 2002. The NAV system has a 4.9 inch screen and is DVD based. It uses just one disc for all of the U.S. and parts of Canada, and features turn-by-turn directions with voice prompts in English, French-Canadian or Spanish. It has extensive listings of points of interest, automatic re-route calculation, written directions, and enough memory to store 100 personal addresses. Also included is a single slot CD player with CD changer controls. Sirius Satellite Radio® capable. The MSRP for the RB1 is $1795 with an availability date scheduled for Nov. 25th, 2002. Some dealers may receive models earlier.

As far as we know, the RB1 will plug directly into any 2002 or 2003 model WJ. The antenna for the NAV system also needs to be installed, and is routed behind the instrument cluster. The RB1 should be able to be installed in 1999-2001 models, and if so, would require the Chrysler 82207541 radio adaptor harness kit. At this time, for unknown reasons, the kit does not include a provision to hook-up the factory 10-disc changer.

The radio portion features 30 station presets, 10 each for AM, FM and the Sirius Satellite Radio system.

First-generation Mopar system
(discontinued in 2002)

Available as an accessory for all WJ models, the Mopar Navigation System mounts next to the radio via a special bracket. According to the brochure, using the Global Positioning Satellite (GPS) Network orbiting the earth, along with information from sensors inside the vehicle, the navigation system quickly and accurately determines your position within 30 feet. Then, using this information, it leads you through the exact route to driving using large, easy to understand icons. In addition, the system uses voice commands that guide you through your trip, mile by mile, turn by turn, until you reach your final destination.

Other features include address checking, automatic trip rerouting, most-efficient trip calculation, shortest routes and route customization. Also claimed is a program developed specifically for off-roading featuring Longitude, Latitude, compass readings, and altitude above sea level.

The system has a list price of $1800, which does not include installation. The U.S. maps are divided into 3 discs (Eastern, Central, Western), one of which is included free with the system. Update CDs are released yearly and sold through Mopar dealers. The screen is small, and the system is CD based but many users stated it was very accurate. Other companies offer DVD based systems with larger screens but some require changing or adding a CD/DVD head unit. Magellan offers a portable system that can be carried around or moved between vehicles. Alpine, Kenwood and Pioneer also offer NAV units in the $1000-$2000 and up range.
