I have just gone and bought myself the Garmin 64ST, and I was reading a review afterwards (stupidly) and it stated that when you change the batteries that you loose all track, waypoints and routes data.
Has anyone used a 64 and come across this problem?
I assume that it would be more beneficial to carry around a battery charging kit (similar to Powermonkey approved by Garmin) instead of a spare set of AA batteries so that i can charge the set that is in the unit and potentially not loose data.
