📻 PAC OS5 OS-5 Radio Replacement Interface with Onstar & Retention, Black, 9.00x9.00x1.90 Review

Bought for an 07 Tahoe with Premium Bose, no sat nav, it worked! Don't forget the steering wheel switch module, which is a separate piece that plugs into OS-5.

Works correctly approximately 70% of the time. Sometimes turning up the volume actually turns it off, turning it down turns it off, etc. It's not overly impressive.

Installation is a lot easier than you think. Read the instructions. I just hate the fact that I had to buy this to replace my radio, but that's GM's fault. PAC seems to do everything it claims to do.

Joshua Garfinkle: This product does not work as advertised in my 2013 Chevrolet Silverado pickup, connection to Pioneer App Radio 4 allowed some of the steering wheel controls but eliminated many of the key ones and eliminated some of the functionality from onstar, voice control and emergency assistance. Buyer beware

No features for 2010 Cadillac Escalade ESV. The rear LCD is not receiving a signal. The instructions mention the issue but are VERY vague on how to fix it. He refers to a purple plug that doesn't exist and suggests connecting a wire from one point of that plug to another. Ridiculous. Why not give better instructions? Floorstanding speakers don't work either. Sound comes from everything else except for the tweeters on the stands. That's important to me because it makes the system sound too rosy.

This could be a good harness/module. But I believe this item may have caused electrical problems in my 2011 Impala. I got error codes, checked them at a good shop in town and they said the car was fine. This led me to believe that this was the case. unit revolution. Among other error codes I received "Service Stabilitrak", "Service Brake Assist". For example, faults in the transmission control unit (note slippage / slightly rougher shifting). Eventually my entire dashboard/cluster went offline.
