I just got near home and decided to make a call. I stopped and luckily noticed my tom tom was about to fall off the mount. The screws that hold the ram mount to the dock were all loose and one had fallen out and got lost. When I checked the manual, I noticed washers! I can't find any in the pack. What have I done wrong here? Also, does anyone at Tom Tom know the screw spec and how to get a replacement? Pic attached of the bit I am talking about. Thank you.
