4.0 out of 5 stars Easy to Install (Even TWICE!), February 18, 2010

This review is from: Axxess GMOS-01 02-Up Onstar Harness Adapter with Chime (Electronics)

I purchased this adapter to install an aftermarket radio into my 2004 GMC Envoy. It was very easy to install and works as described. The "chime" that it replaces the factory chime with is a bit awkward sounding at first, but it isn't all that bad.

Just incase you're not entirely sure what this does... In some vehicles (I'm not sure exactly which ones so you'll have to do your own research), the factory installed radios control various other functions such as the chimes. In my 2004 Envoy, the radio also stays on after you turn off the truck until you open a door. This feature and the chimes are lost if you remove the factory radio without using the GMOS-01 adapter.

Just make sure it functions properly BEFORE you button everything up! I received a faulty unit the first time around and had to wait for a couple of days to get a new one. If your chimes don't work (the unit's default volume is loud enough) or if the radio stays on after you open your door, then it's a bad unit.

OH, and don't forget to buy an antenna adapter as well if you're installing into a newer GM! They use a mini antenna connection that you have to convert into the larger type that aftermarket radios use. Amazon sells the adapter for about ten bucks or so.

1.0 out of 5 stars Overpriced POS!, September 1, 2011

This review is from: Axxess GMOS-01 02-Up Onstar Harness Adapter with Chime (Electronics)

This is the most cheaply made, overpriced POS! I ordered one for my 02' Envoy and installed it following directions to a tee. Directions were very easy and well written. The chimes and Onstar worked but the reciever would not turn on. I returned it for a replacement and the next unit turned the radio on, but I had no chimes or Onstar and the radio would not shut off! I had to turn off manually...even with the key out of the ignition. I called Access direct for tech support with no luck. It was another defective unit! Now I am waiting for a third one. Hopefully the third time is the charm. I looked into this product and found that is has alot of problems. Unfortunatly, you will need it for Onstar, chimes and memory when you turn off the vehicle. I will use another brand if this one arrives defective.
Ok...Got the third one in and it works. All of the chimes do not...like my low fuel chime for example. I was going to try another brand if this one didn't work right. I still want to send it back, but I think I can live without some of the chimes not working. Go with another brand IMO.

5.0 out of 5 stars Worked on my 2003 Rendezvous, October 25, 2011

The worst thing about this product is the price! It wasn't too hard to install myself, though. One nice thing about this product is that you can lower the chime volume (which I did!). As the title says, it worked on a 2003 Buick Rendezvous.
