I know most of you guys have so much more by way of audio in your TB's and Voys... but I am tickled pink!! My Voy is an 06 XL Denali, which had the CD/ Cassette w/ Bose unit... and I wanted more.. so I did a little research on Crutchfield, and got lucky and came across a used Pioneer AVH-P8400BH head unit.. and the local installer had the adaptors needed to retain Bose/Onstar/Chimes, antenna adaptor, as well as Steering wheel controls.. and I couldn't be happier with the outcome.. now to get the amp and sub, and I'm set 



Thanks to the people on this forum, or I would've never even thought of exchanging out the head unit..
Peace
