Metra VT-GMRC-01 GM Class II Data bus Interface
Problem: Installing an aftermarket receiver in many late model GM vehicles means losing the chime that warns the door is open, along with audible safety warnings.
Solution: Metra's VT-GMRC-01 GM Class II Data Bus Interface lets you replace the factory receiver in these vehicles and keep the door chime and all audible safety warnings.
Hook the VT-GMRC-01 to your aftermarket radio, mount the module in a location where the chime can be heard, and plug it into the existing factory plug. Get the great sound you want, and keep all important safety features intact. The VT-GMRC-01 will not work with OnStar equipped vehicles. 1-year warranty.
