Hi, I was wondering if there is a double din HU out there that delivers exceptional sound quality as well as the perks of having the larger screen and navigation if possible. I am leaning towards a pioneer HU only because I've owned them before and love the sound. Sound quality is my priority, second would be ipod connectivity and then navigation and siriusXM. Would I get really good quality of sound from the AVIC-Z140BH? Say in comparison to the 80PRS? Thanks for any feedback you can provide!
