I didn't realize xGPS came out with their Turn by Turn voice version while I was away on vaca. Loaded it and went to the grocery store. Works great though the voice is in meters (not a biggie).
I've not bought my new car yet. Leaning towards a Hyundai Santa Fe. They use an LG Nav but it's apparently limited. I can't just plug in a backup camera for instance though the 2009 has iPod integration.
My problem is the mfrs like Dice, USA spec, etc. don't make anything for Hyundai. I was told by iSimple (who just came out with harnesses for Hyundai) that their harness won't work with the Nav, only the Non-nav car. Something about how it handles the xm or aux? I guess IDK IF I can somehow integrate video on this Nav. If the Apple cable can be plugged into it or not.
What I'd like is this - the Mimo 7" USB monitor http://www.mimomonitors.com/
And some way to use it with the iPhone. I wonder if there's a way to hook up the monitor with a wireless USB. Course I wouldn't have a clue how to deal with audio.
