I found another dashboard center tray on eBay and bought it along w/ the rubber mat. I kept that one as an intact replacement and then drilled holes into the original and bolted the RAM-Mount to it for the Garmin eMap.
Things I like about the RAM-Mount: quality of the components, ease of use, and by using additional adapters, I can use it to hold onto practically anything, even my Olympus digital camera.
Things I do not like about the product: Nothing yet.
I was given a Lev-O-Gage by a friend of mine and using the included doublesided tape, attached it to the front of the tray.
Things I like about the product: It's just fun. It wasn't yet installed when I was on Fire Road 42 on November 2nd, but we were at least at 30 degrees of tilt to the left and right during the "initial test run".
Things I do not like about the product: Nothing yet.
