If i can get either for the same price which ones better for Sound Quality and adjustments.

Dont really care about Navi

 

alot of guys i know who have great sucesss in the sq use pioneer randy st syr , keith mcumber , mike maltais and all the guys from that shop all use pioneer , randys sponsord by team pioneer and keiths a pioneer dealer so im sure they would be more then willing to talk about both of those units and suggest the best for what you need
