First Off The Chime Will Still Work And So Will The Keyless Entry.you Do Not Need To Hide It In The Trunk. The 05 Is Gm-lan The Old Databus 2 Runs All That. If You Still Want Your Dic, Metra 99-3303 Has The Spot For The Radio And The Dic Below It. It Is A Nice Setup. You Will Not Lose Any Functions Of Your Car When You Change The Radio. Anyone Who Tells You Different From No One Are Morons And Should Not Post About The Radios. I Have Had An Aftermarket In My Dash Since I Bought The Car. I Have Also Been Doing Proffesional Installation For Ten Years, On A Competition And Sound Quality Level.
