No way. I've had my Garmin for seven years and after changing the battery last year, it's as good as new.

To the OP, try using it on a different .GPX file and see what happens. Also, try entering a destination yourself, either using an address or the points of interest functions and see if that works. Your issue could be with the file -- especially if everything else works.

Unfortunately, Garmin's support isn't always good at providing useful tips that can solve annoying problems with their devices. A perfect example is ride mileage calculation. Garmin devices are set by default to take that from GPS, but that won't be as taking it from the wheel sensor and manually entering your wheel circumference.
