Great Product

The PAC OS-3 is a must have product when adding an after market stereo to your GM vehicle. I highly recommend it. It keeps all of the factory features such as chimes, on star and it also has the steering wheel control wires so you don't have to look for them behind the steering wheel (Must add Optional harness). Its simple to install I did myself in about 1 hour and it works great. HIGHLY RECOMMENDED.
