Sorry, yeah I should have been a little clearer. I swapped out everything. But the main thing, was that the shop didnt know if the $15 harness listed for a car without bose/onstar would mate up to the factory harness plug end for a car with those things. It did. They were unsure because they just had a listing for the $100 item mentioned earlier and said the ends could be different. Anyone that ever had bose in a GP just got the "proper" kit in their experience. Thats great if you want to try to keep everything original as possible in regards to warning sounds, but I'm sure glad I dont have that "dinging" when the doors are open now
On a side note, I kinda miss the steering wheel controls too going aftermarket because I'll forget and try to use them. But its a worth while trade off. Steering wheel controls can be restored, but I'm not concerned.
