I remember something like this happening.. I spent 5+ hours installing 2 two-way radios and a mobile phone hands free kit into a security patrol car. Later the next day the car was stolen. Was recovered a few days later. They took all the radios and the cradle for the mobile phone hands free. Didn't take the unit that actually controls everything. They also took the amber light bar, the rims and other random stuff. Ah, the factory stereo they also stole and probably damaged quite badly. I had to do it ALL over again.. Man.. I loathe working on Commodores. Shit interiors to work with.
Avoid working on Commodores if you can.. They really do suck.
