PAC C2R-GM24 GM Chime and Data-Bus Integration Interface

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!

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.

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.

Needed to purchase this for my car's deck upgrade. Bought it here for less than 1/3 of the cost at my local retailer. And the installation to my new deck was quick and easy after taking a few minutes to read the instructions, just connect the same color wires to your decks wires. Couldn't be happier with the product I received, came quickly from the seller. Mine was the dark blue colored deck harness (the computer chip plastic box) instead of the grey one. Maybe it varies, but just saying which one to maybe to refer to in the pictures, but cant guarantee.TIP!!!!!!! ---- NOT all wires will be used. I was freaking out cause not all my wires were being used but I had about 2 wires not be used in the end from the deck I think. The "dimmer" and "remote" wire did not get used for me. Also, since i do not have a Boss sound system, you cut off the RCA connectors and splice the wires to their appropriate wire. It's all color coded. But just some tips that I think would be helpful.I do have a picture if anyone wanted it. May not be extremely helpful, but just something to maybe see. Can just send me an email and ill send it to you.

Why it should ever take Amazon three business days or more to ship an in stock item is beyond me.Further, they never indicate where an item is shipped from, so you have no intellegent way to select shipping methods. Wherever I have a reasonable alternate choice , I will be using other suppliers in the future.I'd review the product itself, but since it still has not shipped, I can't. One star for Amazon order processing, which remains my long standing number one complaint about Amazon.

Needed for my friends truck for radio I put in for him. The first one I bought has to be defective because the module box would not go off and would make the radio come on by itself, even if the car was off. So I went ahead and called the company itself, and explained what was going on. They said that it had to be defective.So I ordered another, and like magic, worked perfectly, with no problems at all, and did not stay on. Just make sure you don't get a defective one!!!!

The chime on this thing sounds like it wants to be put out of it's misery. Its a cheap single speaking in that blue box that replaces your car's chimes. This also controls power to the radio when the key is out (keeps it on until you open the door or 10? minutes).Due to a problem with my old system I had to replace just the blue part, so I soldered the wires properly and it works just fine.My only complains are the price of these things, and the quality of that little speaker.Enjoy!

I used this on a 2003 Chevy Malibu to install a nice aftermarket stereo system. It gave a wire-splice free, clean install and kept the electronic systems from having any issues.
