Does anyone use a different mount for the handheld screen? I have a RAM mount for my cell phone that works awesome, even off road, was wondering if anyone used one, and which one? I know I saw something mentioned somewhere about what "size" GPS was compatible or something? If anyone knows that I'd appreciate it! I am sure the novelty of the screen will wear off (and I'll want to hide it from looky-loos), but I think having another gauge reference is always handy!
