With the 24.18 release may Edge 1040 Solar does has multiple issues :
1) With two tracks displayed, i was sliding the map to search wher to go, whne the GPS crash and reboot
2 ) Routing is not usable
2.1) Track routing does not works : when started, it stucked in routing calculation at 17%
2.2) Once routing statted, GPS becomes ultra slow between any action (pages slide, zoom...), it tooks several seconds (or minutes) before Respons !!!
I would like to completely reset the GPS, starting with formatting it, then reloading all the software; how to do this ?
