Anyone use the Garmin C530 I am thinking of buying one at a pretty good price but was wondering if this unit is any good. Can it be hard wired, does Ram make a mount for it and if so does it mount easily. does it lose reception in mountain ranges, I know it is not waterproof but that is really not an issue with me as I would be using it mostly in my car and maybe 3 times a year on the bike and would just remove it should rain become a problem. Any input would be greatly appreciated.
