To clarify, this gizmo only works if you have the HU that came with the m/t package? Meaning, it would not work on the HU w/ nav system?

The local Pontiac dealer spent the day trying to diagnose my Nav System woes (It has been takening a longer ammount of time to get a GPS signal lock and the system has failed to boot up on three ocassions.) The dealer could not get the boot error to repeat. And when the dealer's techs consulted the ...

It is taking noticbly longer to get GPS signal lock. Also today, for the second time, the system did not fully tun on. When I started the car, the screen was bank. Not even a clock display. The radio played the previously set station, but the unit was unuseable. None of the buttons functioned. After...

Anyone have the part number for the Nav System display unit found in the 04 vibes?Mine is dying. Got any suggestions for a replacement?Damn warranty just expired (40,000 miles). I have had the car for a year and half. I am not impressed. Anyone else had this problem?

For the last two weeks my nav system has failed to recognize my location prior to 6 am. When I leave my garage @ 5:30 am, the Nav system recoginzes my location (home). But when I start moving, the Nav system shows me moving in different directions that what I am actually driving. By the time I get t...

My Nav system burped the other day. I have an 04. I started the car and the radio came on, but the Nav system did not fire up. I was able to turn the radio on and off, but nothing else worked.I even turned the car off and restarted, but nothing happened. About 5 mintues later the system kicked on an...

GM Parts Direct lists the price @ $246.53, but I can't find any information on how current the data is.
