Interested to see this completed. I was thinking of doing the same thing down the road.
I have a 2012 so it shouldn't be changed from the interior of the 13.
No difference in the mounting options that I looked at, I wanted to avoid a windshield mount but also didn't want to make any permanent changes so that's made this a little more difficult that it should have been.
Unless I change my mind again, I'm going to use two of the ProClip mounts and connect them with a piece of aluminum. That will allow the tablet to be center mounted instead of offset to one side like ProClip shows. Sent from AutoGuide.com Free App
