I just spotted these new posts on the thread i had started and thought i should mention that there are different plugs on the back of the radios depending on who made the radio. the mitsubishi ones had a 7 pin din and the american made ones had an 8 pin din. i think accustar or something was the name of the ones used in DSM cars, they look similar to the mitsubishi ones on the face but but with black knobs and buttons and are very different internally. I think, if memory serves me that the alpine radios shared that same connector but are wired differently. i would not connect an alpine changer or Bluetooth without verifying the pinout first!
