How's this stand up to the vibes? Is it hardwired or AA powered? I've had no problems with vibrations. The RAM mount is very solid. I like how you can adjust where the GPS unit is. It's not hard wired yet. I just use batteries but I think I'll get the wiring kit that is available. After reading this thread, I need to learn how to better utilize the features that are available. I need to find out what is the best software for off roading. Any recommendations?
