HOLDEN has offered the Philips CARiN satellite navigation system across all Commodore models since March 1999. The system covers all mainland capitals and close to 100,000km of bitumen. Holden Special Vehicles has offered the system since November 1998. Holden will offer an optional telematics communication system for Commodore from around March 2001. The system is being developed in conjunction with NRMA and RACV. It will offer one button access to roadside assistance, emergency services, vehicle unlock, vehicle tracking and vehicle immobilisation. Holden is promising greater capabilities in the future.
