I believe you will be able to do it, if you can find the part. Did you try the Cadillac dealer in California? He at least does try to help out.
I called him about the XM, and right now it is a no-go. He thinks GM's supply is low, so they are on restriction. The only way the dealer can get one is to send the bad one back. He seems to think this will change when GM catches up, and we will be able to order them.
Anyway, I am not too eager to install a CD changer. I would like XM and an AUX connection for a digital music player. Blitzsafe is working on an Ipod adapter that will allow the factory head unit to control and charge the Ipod. Why worry about carrying and changing CDs when you can carry your entire music library!
Anyway, best of luck getting that changer installed! Please keep us informed of your progress. We all want you to get plenty of exercise using that middle finger!
