Hey guys, I own a 08 Pontiac Grand Prix GP. I have the onstar system and for some reason I get this error intermittently. Every time I seem to go to the dealership they can't find no problems or say they need to rip my interior apart to check every wire. I called Onstar, they told me the malfunction and to go to dealership. So what else can I do to fix the problem? Has anybody had this problem before and what was you fix, I have been thinking I might have to change the vehicle communication unit for onstar. Some of the malfunctions include not being able to use turn-by-turn nav, red light comes on and off. Thanks for help.
