I currently use a Garmin nuvi sat nav on the bike which I power from a lighter socket wired directly to the battery , could I power this sat nav from the bikes loom via the socket by the headstock .
It is a 12 v supply, so using a bmw plug to an adapter is feasable,
using some 5v camera hard wire adapters can trigger later garmin to be in connected to computer mode,
I am exploring this hard wired idea for my camper,
Still working on a 5 v supply that doesnt do this,
