I am planning on removing my old 2din stereo (original) from my MA70 and replacing it with a 2din nissan skyline stereo that was given me. Wont be looking for anything decent for a year or so as othere things come first.....lowering, alloys, etc. I am after advice/instructions on how to remove the old stereo and also if u guys think i will have any problems with security codes when i install the new one.
