Colleagues, I'm planning to install a hard-wired GPS, to get me back home when needed. Anyone know how/where to tap into a switched voltage source in the bike without dismantling everything?
Thanks!
Thanks!
My escort 9500ci radar detector module is in the trunk, so it works to get power from the tail.There are several places to get switched voltage from, after all, things like the parking lamps cut on/off with the ignition. You may have had an issue because of the power draw. If you need a significant amount of power, I would go straight to the battery. You could easily tap into a tail light, let's say, connect a relay and then run + to battery and - to frame.
*edit*
Just saw your second post. That works too but the capacity would be mediocore, plus you still have to run wires to front of bike. At least with a relay out back, you could do heated gear as well as multiple accessories.

I'd be fine with a relay, but the issue was that I could not get switched power from the lap timer connector that looks "normal", i.e. went to 0v and +12v when the ignition went on. I looked at the wiring diagram and found that the ECU was involved inthe laptime connections so that plus measurements with a voltmeter led me to give up on the laptimer connector approach. As I recall others had a similar experience with trying to get power from the lap timer connector.
plug on fairing --> part in post #8 --> connect to power adapter --> hook power adapter to USB --> phone
Your suggestion works great for just charging. But for charging and viewing navigation it's cleaner to go with OEM power plug on left fairing, no need to run any long wires. Too bad not many people run that setup.Or buy the usb stick I suggested if you're just looking to keep a phone charged.

I don't get it, BMW put a switched power plug in left fairing exactly for a phone/GPS. Most people seem to utilize it. Most people go for known option (directly to battery, run long cable). I wish if there were more info about it.
Literally.It's the path of least resistance.
Literally.
And you probably have/want a battery charger pigtail wired to the battery anyway so you are already half done.
Do you have to remove the gas tank to snake the cable from battery to front of bike? I'm familiar with dirt bikes, I cannot think of a neat way to get a cable from battery to mount close to steering stem on a sportsbike.Not sure what else you're looking for. This thread has plenty of info if you're looking to use the aux plug. Some of us just like to go back to the battery. It's easy to do. It's the path of least resistance.
There is a DIY on here by Frankoq if you want to install a fuse box. What more would you like?

This is the route I found to be best. Great info in this thread! Some questions:I made this up from the BMW cable and a water resistant 12v to 5v DC to DC converter USB cable.
