My Garmin Geko is taking an age to find a location when switched on. It used to take about a minute, and I seem to remember that all the satellites previouly plotted were saved and immediately shown on the sky display, if not logged. Now every time I switch on it's like it's doing it's first search/initialisation.
Anyone have any ideas? I've tried reloading the firmware, the only other thing I wondered was do they have a little internal battery that may need replacing?
