Well the intention is simple, remove DSP, TV, satnav, radio module and head unit. use exiting speaker wires on output side of DSP and wire to speaker out of after market head unit. Run permanent +ve 12V line fused from battery to head unit and uncover a temporary +ve 12v line in the head unit area. then add on peripherals as required that i know work with my Kenwood. should be pretty straight forward after I get the MID to work!!
