    From the manual:

    NOTE: The red system power cable may include an in-line fuse on some device models. Cables without an inline fuse are protected internally.

    I have never really understood the need for fuse to protect the GPS on a motorcycle. I think the main purpose of bike fuses is to protect the wiring harness from burning up due to a short to ground.

    It seems implausible that the bike's electrical system could put out such an overvoltage to damage electronics. It seems like it is all the stator/rectifier/regulator system can do to put out 14v.
    I guess this could rise a little if the regulator failed.

    Maybe some guys have accidentally put in a 100v battery instead of a 12v.

    But I would be happy to be educated as to what the plausible threat is.
