I own a 2005 STS 1SG w/ AWD, HUD, ACC. the problem I have is about every two or three times I crank the car and agree with the warning screen I get a message that the Map DVD is not installed or it is not a Map DVD. However, it is installed and is correct. The only way I've found to correct this isue is to cut the car off wait about 10 minutes and recrank which is annoying. Anybody have any suggestions?
By the way, I understand that the Map DVD cost $900.00 to replace... Can it be copyed?
