The Mopar RB1 Navigation Radio will be available on select 2004-model vehicles from the Chrysler Group, either as a dealer-installed, or as a factory-installed option. The system is said to be able to guide drivers to any location in the U.S., using voice commands or a dashboard-mounted screen.The Navigation Radio system is housed in the center of the dashboard, allowing easy access for both driver and front passenger. “Through the use of global positioning satellites (GPS), the system effectively calculates the quickest and most accurate route. It also immediately redirects the vehicle should the driver veer off the path. (Drivers) may never have to stop and ask for directions again,” said Jack Withrow, director of Vehicle Entertainment and Communications for the Chrysler Group.The system was developed through cooperation with Alpine Electronics. The map database information is housed on a single DVD-ROM based on data from Navtech. The system receives its GPS signals from up to eight satellites, and combines that with information from an in-vehicle gyroscope and the vehicle’s speed sensor system to display the present vehicle position even if the satellite signal is not available. When a destination is entered, the system uses data from the DVD to calculate the route.The system is available as a factory-installed option on the 2004 Jeep Grand Cherokee and the Chrysler 300M. As a dealer-installed option, it is offered on the 2004 Chrysler PT Cruiser, 300M, Concorde, Sebring Sedan, Sebring Convertible, Pacifica, and Town & Country; on the Dodge SRT-4, Stratus Sedan, Intrepid, Caravan, Grand Caravan, Dakota, Ram, and Viper; and on the Jeep Liberty and Grand Cherokee. The factory-installed system will cost $1,200 - $1,595 depending upon the equipment package on the vehicle. The dealer-installed system will cost $1,595 plus installation labor.
