Still reckon the wiring was either damaged or put back wrong with engine going back into frame.
Can you take pics of what the GPS is connected to?
To verify it is plugged in correctly - Roadsters pre March 2013 have a convoluted way of connecting the 4 wire GPS up.
Thanks, I will do. I’ve read up on the three to four wire transition. I was also not ruling out plugging in incorrectly, but cannot find any other plug : socket that would fit. The GPS plugged into a mini wiring loom with the sidestand switch
