I have a 2011 F800GS, with a GPS bracket thing so that I can mount stuff above the instrument cluster (see image). This also comes with a circular hole to mount a socket accessory into, and I'd love to install a USB power socket there, so I can charge my phone.
However, I am a bit lost, I don't know what to buy and what will work. I've found a USB socket from Wunderlich that connects directly to the battery, but I've read that this is not a good idea as it'll drain the battery even when nothing is plugged into the USB socket. They also have a version of a USB socket with a power switch, but that just seems like a typical thing to forget to turn off. And there are sockets from Wunderlich and Touratech that are supposed to replace the DIN socket next to the keyhole ("plug and play"), but I really would like the USB socket to be placed into the empty bracket closer to my phone.
I've also read that there should be a CAN BUS plug underneath the fake tank cover, which shuts off when the engine is turned off, so that seems perfect. But which USB socket connects to it?
Can someone point me towards a solution? So a USB socket that inserts into the bracket from the picture, which doesn't drain the battery.
