DIC Funtions after Installing Aftermarket Deck

I looked at a 2005 GTP last night that Ive been considering buying. However at some point prior to the present owner an aftermarket deck got installed (Pioneer). Anyways none of the DIC functions work. You can't change any settings, you cant reset the oil life, your trip mileage, view the date, etc. The owner claims that they were told it was due to the after market radio?


Is this the issue? What would regain the functionality of all of this? I know from what I was told before the only thing that would function is the date display. Is it possible the deck was installed improperly or they didn't use the right adapter? However the door chime seems to work.
 


The only thing you should have lost would be the calender function, mine will no longer keep dates or anything, but besides that everything else functions correctly. I've tried it with 3 different aftermarket HU's, two Kenwoods and now a double-DIN JVC.

I used this adapter in line though so that may have been why: Metra GMOS-01 GM Factory Integration Adapter Retains OnStar® and factory door chime with aftermarket radio in select GM vehicles at Crutchfield.com

Not guaranteeing that it will solve your problem but mine works fine. I disabled/cut the wires on everything relating to OnStar or door chimes though, because that stuff annoys the hell out of me.

+1. I just installed a Pioneer double DIN in my car and all I lost was the calender function.

It sounds like your DIC is broken...
