Kizashi Club

I'm not interested in Nav, but if I end up with it, for lack of non-nav availabiity, what differences should I expect in sound quality, and operation, with radio/iPod?

When I saw the Nav unit at the dealer (some had a Kenwood logo, others a Suzuki logo) I first thought it was an aftermarket unit swapped in by the dealer. Not very slick - or secure -looking.

Thanks for any input!
