Got a 96 z34 and i want to change out the stock stereo with my aftermarket one. i have heard rumors that there are some theft lock crap and if i pul the stereo it could damage te car. now i have swapped stereos in all my previous cars, but i've been hearing alot of these rumors so im a little nervous. so my question is: are these rumors true? if not is there anything that i should pay special attention to. your input is GREATLY appreciated!!!
