In dash changer in LT help

Hey I was curious is anyone has the 6 disc in dash changer (not the bose version)...and if so what is the part number? Also will other delco in dash changers work in my 02 LT? Lastly, how do I unlock one for use in my vehicle without going to a dealer and paying out the butt..
Thanks!!!

To install another stock radio in the TB you will have to go to the dealer for the unlock. As they have to download the unlock from GM for it to match your vin.
