I've had my Rio Car since the fire sale and I've finally decided to put it in my car (I've been looking for an M3 for the past few months but didn't find one that quite fits).

I was one of the lucky few who were able to purchase a tuner. (In anticipation of the M3) Therein lies my problem.

My current car is a 2n Gen (FC) rx-7. The dash has 2 din spaces. I'm wondering if I should get a good head unit to use as an amp/radio/cd-player. It would cost a little more but I'd have a CD player for music purchased on trips. More importantly I could keep the tuner in it's pristine, unused, condition.

Do those of you using headunits down stream from the rio have any strong good/bad opinions about usability?
