Gasturbine

Hey guys, I have searched the forum, and found some info, but much said "love it" or "Hate it" or "Its junk, dont buy it" comments.

So Im looking to the gurus for some sound advice and direction...

So Ive been doing some research, and it looks like most units feed thru the AUX.

But that brings questions...if I have to switch to AUX, doesnt that mean my radio/CD/NAV/media/Info/HVAC options become unavailable? What happens to my hands free phone, and steering wheel controls? Back up cam?

I prolly have more questions, but maybe someone here can ust give me a laymans explanation.

Plus, Im looking for recommendations for a unit.

Thanks!
