Re: New After Market Radio Affecting Rear Parking Assist?????? HELP
I had a local shop install a JVC KW-NT3HDT in my '10 LT1 Traverse. After the new radio was in, I no longer had chimes, turn signal sounds, nor rear parking assist. I called the shop, who said I could get the sounds back if they installed another module (plus another $150). Due to distance involved (and the fact that I was still mad) I went to another local shop and they installed a PAC OS4 module. The sounds are back but a little different-the turn signal is more of a chime than a click, the chimes are more computer sounding, and the back up alarm definitely sounds different than stock. It does work correctly, however, one chime when I put it in neutral, then silent until I get close, then the faster beeping, then solid. I'd ask your dealer what module he installed, then look at the manufacturer's website to see if it really is fully compatible with your year Traverse.
