Hi Jason, I have the model below this one without the Sat Nav installed in my 08 ZRE Hatch so hopefully I can answer some of your questions for you. Although they are different units given the main difference is the Sat Nav, I assume they function the same way. 1) Not sure if it pauses CD playback on receiving calls, but I know it does when an iPod or USB is connected. I can test this out for you if you like. 2) From what I've read most of the operations of the Sat Nav are locked out even to the passenger (only if you have the speed sensor attached). 3) Not sure about folder names when playing MP3s. I need to get back to you 4) Installation is pretty much plug and play. You may need to get a harness for the aerial cable and steering wheel controls if you have them. They changed the aerial plug on the newer units to a square plug type which I assume is to accommodate the new Digital Radio functions. 5) From what I've read you can move around on the map (you'll need to verify this yourself thou) 6) For the most part Bluetooth has been solid. I currently use a Galaxy S3 and it works flawlessly (even the Text to Speech function for messages you receive works). Previous to that I had an iPhone and that worked with no issue either. For unit to sync up with your messages the phone must support the Bluetooth MAP Profile.
