    I had the BOSE in my '03 Av... I'm fairly certail that they are the same... Here's the diagram I used... It will be on that page... I used that when I got the METRA GMOS-04 Adapter and it **** the bed 8 hours after I installed it... So I used the factory side of the adpter and direct wired it to my new head unit. All I had to do was run an ignition power wire from the fuse box and everything worked perfectly... But in doing this you lose all warning chimes, and the delayed shut-off...

    Hope this helps...
