Guys,
I finally did it. I replaced the becker unit with a Kenwood MP3 receiver and boy it does sounded sweet. the unit fit prefectly in the slot. no mod at all. almost factory look. The wiring is simple just connect the speakers wires and the powers. The amp power to the antenna power and that's it..couldn't believe it is that simple. I am using the factory bose amp and speakers.
