yep sat nav is spot on. Sound quality is a bit of a tricky one, its not brilliant if im honest and i did notice it wasnt as clear as the rcd500 but it does have more bass. Something else thats bothering me is when youve got your music on low volume the bass doesnt seem to be as quiet as the vocals if you get me? but when you turn it right up the bass is a bit lacking, probably me just being picky but you cant expect everything for that price. Im sure my last one wasnt like that so mabie theres a slight problem with the version i have. I would of thought so yes as there is a can-bus converter, i only have the midline so cant gaurantee it im afraid, bluetooth works fine also.
