I don't know about nav. systems (b/c I don't want one), but if it's music you're after, I LOVE the USB port on my HUs. I purchased the units I did specifically b/c they have the USB port. That's the only way to go! I have about 2.75GB of music on a 4GB stick. That's ALL the music on my computer that I might ever want to hear. I just put it on random and I'm good to go. I like to be surprised! :hihi:
And there's no messing with the Ipod, controls, extra cords, etc.
