Went for a short ride today and my Garmin 2720 won't acquire any sattelites.... It worked fine 3 days ago...I keep my bike in my garage and its pretty humid in there because I'm always hosing out the dog kennel....do you think this is a humidity problem? Brought it in the house and have it near my air conditioner hoping it will " dry " out..I have a nuvi 250 that I can use when I go to MD...Just wondering if I'm on the right track....I'D rather have my 2720...I'M just more comfortable using it...Any ideas......... ps... I have power and all other systems seem to work just fine except for the navagating.............
