2006 Chevy Silverado, radio harness adapter?

I want to install an after market CD Radio in my 2006 Chevy Silverado. The salesman came out to the truck to listen if the warning chimes sound through the dirvers side speaker, and they do. He said I need an adapter in order to install the radio at a cost for the adapter of $119.00. Is this really necessary?

Yes it is. Your radio works on the Class II data bus circuit and is a vital component. If you choose to remove it you must use a module to handle some of the functions that the factory radio controls, such as the chimes. The module will also give you a retained accessory source of power to turn on your new radio. If your truck has Onstar, there are modules that will also keep it intact.

Yes, you really should use the chime interface. $119 is a little high for the module though, you should be able to get it cheaper. The GMCHIME from SoundGate you can get at $87.95 off of there website (soundgate.com) and you get free 3 day shipping with it.

If you have on star, use the OS2 Bose, and the CM1 module from PAC....

The radio is part of the databus system, but is not a vital component. You won't have issues with check engine lights, airbags, etc. if you don't use the module. If you do not have onstar or bose you can use a standard $15 harness, but you will have to run an accessory lead, the factory harness does not have one. And as said above, you will lose the chime and the RAP feature.

Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

Here in the Great White North, it is illegal to remove a safety device. The chimes are classified as a safety device as they indicate to the driver if their seatbelt is not worn. Play it safe and do it proper with the appropriate interface harness.
