Thanks Peter,
No it just goes straight to the quick Cal mode regardless of how long the menu + buttons are held.
It should be just as simple as setting it to read speed from gps using nmea out from gps and not a paddle wheel?? Its not really talking, just listening.........
Its pretty annoying, dont really want to bring it into a merc dealer and pay them for pressing a few buttons...
Its running version 2.80 perhaps this needs updating??
