Regarding GPS read out ,press speed and depth together and cycle to speed calibrate by three pushes of the speed button and a GPS speed read out appears ,pressing reset corrects the speed readout ,of course only in still water conditions ,OK in the Med with no tides,I think Ive got it right boat and manuals are in Spain
