I’m just fitting a nav unit to the bike and it needs a switched live. Just wondering where the best / easiest place is to pick one up. Any advice appreciated.

I've used the instrument lighting circuitry for switched live in the past. Pretty easy to find, and you're not interfering with anything too important.
My bikes are Rocksters, so they use the R1100S instrument cluster which is probably a little different to the GS one - but I think the idea is still valid.
On the R1100S/Rockster cluster, each individual illumination bulb has it's own power wire in the loom coming from the junction just behind the headstock. Splice in a feed to a relay and you've got a switched live.

Thanks for the suggestions, all sorted.
So you then had to feed your sat nav with a wire back up to the front! If you’d used the side light feed in the headlight you would be straight out of the headlight and to the unitOK….so the power lead had to go to the battery, so the ACC wire was basically under the seat by the battery. It seemed to be a good idea to pick up the switched live from a side light as suggested. Once I got into it, the easiest route was to follow the wiring harness to the rear light. I connected up to the side light side of the rear bulb by soldering to the existing spade connector, so no messing with the harness.


The sidelight/tail light is just the trigger, not the feed. Or should be. But agreed, running back to the tail light is an unusual choice even if it does what’s needed!So you then had to feed your sat nav with a wire back up to the front!

Depends on year of bikes and if you have a bike with an on/off light switch, otherwise you’d have to switch on the light switch to switch on the sat nav. On Later bikes the lights switch on with the ignitionSo you then had to feed your sat nav with a wire back up to the front!

Would you mind doing a write up of it when you've used it a bit?It’s the Chingee A10-05. It does Android Auto and CarPlay, plus other stuff.
