im getting ready to purchase a 86 300zx turbo automatic (my first z) and wondered since it has all the original stereo stuff in it, a few q's. Firstly, what is this betty i keep hearing about? Also the steering wheel has all these nifty buttons on it ( i think for the radio) and wondered if any of them worked with a new stereo installation? feel free to call me a moron if i am asking q's that make you laugh or want to cry or shoot yourself in the foot. it happens all the time.
