Anybody have the u310bt and have OnStar in their vehicle..

My OnStar doesn't get power all the time..will not light up at all.

The dealership says it's because the after market radio is causing problems when it goes to power on

according to them as long as I have this radio the OnStar will not function properly...

 

Has anybody else ran across this problem?

the wire harnesses that retain OnStar handles all the powering of the system, as long as you get the right harness, you shouldn't have any problems with the OnStar.

 

which harness are you using? what type of vehicle is it in (including year)?
