Fighting With Dealer

Metro12 · February 23, 2008

Ok, last month I replaced my radio with a factory OEM Navigation unit. I had a dealer do the VIN learn, and they played with it for about an hour, not sure why the audio was really really low. They wanted me to come back and pay $75 to do a electrical diagnostic, and said I may need to buy some harness. Well, after some help here on the board, I found out I needed an amp. I installed it myselfand no issues.

Well, last week, I noticed I had no cell phone service through my OnStar. When I hit the phone button, it connected me to OnStar, saying I have no phone plan (which I do, through Verizon). I finally get OnStar tech support, and they tell me I need to go to the dealer and have a VCIM reflash, due to me disconnecting the battery (was trying to reset the naviagation unit to miles insted of km). So, being that I felt I was getting a bit of a run around at the one dealer, I drove the extra miles to where I bought the truck. They looked at it for about 3 hours. They said they could not "wake up" the module. The service advisor said they belived it was the radio I put in the truck, and would not be a warranty issue. I told her I didn't beleive that. I explained that I think its all OnStar. I asked how I could connect to OnStar, through the cell network, and talk to them through the radio handsfree stuff, and it still be an issue with the raido? The OnStar system uses Verizons network. My sales guy was standing there at this point, as I was trying to explain why I thought I was right. She walked back to check with the tech. My salesman told me he would talk to the owner if this isn't dealt with (between me and buddy, we spent about 60k dollars this year, and I got him bussiness from my neighbor as well!). Well, the advisor comes back, and says they are going to order a (VIS?) and try that, and it should be warranty work, if that fixes it.

So, does this all sound correct, or am I wrong, or is there another possible issue they are not seeing?

sounds about right. the vcim and radio are connected to each other and very related system wise

Yea,I would say they are on the right track.

Let us know what happens,I still may install a NAV radio in mine.

But since I can connect to OnStar through the verizon network, would you still think it may be an issue with the radio, and not with the OnStar module not placing regular hands free phone calls?

Went back to dealer friday. They replaced the VCIM (or something close to that). OnStar hands free works now!! And, they did cover it under warranty. Also, my front driver tire pressure monitor would not be readable, and show -- on the DIC, about 1 a week, for five minutes. They found a faulty TPMS on the tire, and replaced it as well. So all is well again in my world!!
