I just posted this on css.net and I fell that it should be here as well.
I just had the ALPINE CDA-9885 head unit installed in my 2007 Pontiac G5 GT. All they used was the $15 wire harness, and $20 for the dash kit. I have the pioneer system without onstar, I lost my door chimes and thats it. THE AIRBAG SYSTEM IS NOT ACSSOCIATED WITH THE HEAD UNIT AT ALL!!
I repeatedly asked them about the GMOS - lan 04 system. They assured me over and over that I do not NEED it. I could have bought it and retained these chimes, but honestly, I dont even notice that they are gone.
Some installers say that the lan kit allows the new head unit to connect to the 4 channel amp under the dash. This is also very incorrect.
Right after the head unit was installed, I went to the GM dealership and asked the technicians to hook up my car to their computer just to make sure that I didnt lose any functionality (I was still paranoid about the airbags and such). Everything was working fine, Airbags, turn signals, My amp under the dash was receiving the signal fine ( their computer didnt tell me that, my ears did.)
I hope that I have put to rest some of the questions people have about the 07 systems. I myself was very skeptical before I had this deck installed. My advice is: Do a lot of research, make sure the installer is familiar with the vehicle, and finally JUST DO IT!!
Here are some pics of my system:
