I had one that was on a mount and I found it to be sub-par, despite the fact that it was considered a top of the line device. This new model also integrates to the radio tuner for up to the minute traffic updates through NavTraffic, along with CD and DVD playback.
I am currently inquiring to see if there is anyone working during the holidays who can integrate it into the vehicle in question, in a quick and timely manner, prior to January 3rd, 2013.
