## Description

GM Chime and Data-Bus Integration Interface

Review: It WORKS!!! - I purchased the 'other brand' adapter and it sounded funky, just like this one does. You can't emulate the sound you get from your cars stereo system with a little speaker. Get over it. It bongs when it should, and you get the message. Your unhappiness should be directed at Chevrolet, who is obviously trying to make us buy the Factory $y$tem instead of aftermarket. The big difference is that the 'other brand' unit would mess up. The fix? Just pull the fuse, then it's back in action... and all your radio station presets are gone, and you have to reset the clock, etc. I actually gave up on setting up radio stations, the thing faulted so much. Finally it quit altogether. I saw reviews elsewhere indicating that the PAC unit worked and kept on working, so I gave it a try. It's still working today, and I have yet to have to pull the fuse. I've actually programmed in my radio stations, and I have forgotten how to set the clock. Don't waste time and money on the other one, this one Just WORKS!
Review: Work great but bad sound. - PAC products always seem to work as advertised, and this is no exception. Connectivity is great, and the instructions show you what you need. Pretty much just match up the standard colors for most of it. The only complaint I have is that the chime is a bit loud and sounds kind of cheap. It is hard to describe. I just put a little piece of tape on the speaker to quiet it down a touch. Overall this is great for those people with base level factory radios that they are replacing. This was installed in a 2006 Pontiac GT with no On-Star, and just the base radio. I used this to install a Pioneer DEH-P6200BT without issues.

### ⭐⭐⭐⭐⭐ Needed when bypassing Onstar and the Bose system but keep warning chimes.
*by M***Z on February 14, 2015*

Worked Great when upgrading my factory Bose system with a newer Aftermarket system with multiple amplifiers in my 2004 Cadillac Escalade EXT. I still kept my backup warning chimes and my stereo will still stay on when ignition is turned off. I got rid of the Onstar which I never used or planned to. Since I wasn't going to use the factory Bose amp this allowed me to bypass and run the stereo like an older car. I agree the chime unit is annoyingly loud. I wrapped mine with some shipping foam and zipties and stuffed it in the dash. It still has that distorted ring to it some but not as annoying.
