Alright, here is my situation. I bought a 07 Denali with nav, but not RSE. I really want to get the lockpick and have DVD up front. Since I dont have the RSE, the front wont play DVD. If I get the GMX-320 Lockpick, could I hook a Xbox 360 up to it and hide it in the glove box. That would then give me the capability to play DVDs up front. Does anyone know if that would work?
