Summer time here and we have too change our clocks forward one hour. This and following procedure in Noodle App booklet helped but still lost all my old clock, speedo and weather pic settings. Not happy camper but my digital clock on dash is updated. Only original screen for speedo on my AK550 dash now. It sucks guys......Might buy a Yamaha T Max to replace and hope it's Nav software loads easier and connects with bluetooth easy.
