Here are some pics of my TomTom Go 720 that I got instead of doing a full blown Acura navigation retrofit. In this location it sits there pretty steady and has not once fallen out of its location w/out the use of anything to hold it there. I might eventually use the windshield mount but I don't see the need yet. This is the night mode of the unit, during the day its not blue but normal beige map color. You can hear the unit just fine as it has an FM transmitter built-in to go through the car stereo. Pics of night mode below.
