First let me start by saying this forum has heped me alot. I tried searching the forum but i didn't get what i was looking for. This may sound like a dumb question, but i currently have a Bose Cd player in my 99 GMC Jimmy. I'm wondering if i could put in a Bose cassette stereo in the Jimmy. The only issue that i think i may have is the security code, but i can get that from the dealer, correct?

This is the one i have in mind, also if someone is selling one please PM me.
