The GMCO2 (ver 1.4.5) is a plug-n-play Chime and Data-bus Integration Interface compatible with select 2000-05 GM LeSable, Aurora and Bonneville Class-2 Radios without OnStar® OR Premium BOSE Sound Systems.
Purchase this interface to quickly replace the factory radio with an aftermarket Radio in the vehicles listed in the pull-down menu below. The GMCO2 Enables aftermarket radio installation without retention of the factory radio, replicates factory warning chimes, provides a data-bus generated 12-volt accessory power output that is fully compatible with GM's Retained Accessory Power (RAP) system.
