The R1200GS (Adventure) and R1250GS (Adventure) model series came in various equipment variants. The on-board socket next to the speedometer, or a USB socket next to the speedometer plus the on-board socket under the rider's seat.
In my case there was only the on-board socket next to the speedometer and I also wanted to charge further devices, so the idea was born to install the original BMW USB socket on the other side of the speedometer.
What do we need for the conversion?
The retrofit kit charging socket BMW #61341598766 or a Amazon Alternative with 2x USB
A piece of metal and some mechanical skills
A Y adapter cable, e.g. from Amazon
With the Y adapter cable, the existing on-board socket can be unplugged and the Y cable plugged in between. Then the USB socket and the on-board socket are supplied via it. Charging with the original BMW trickle charger continues to work afterwards.
I mounted the metal piece on the two screws on the left of the frame section next to the speedometer, where the plastic fairing is also screwed on. In my case I fitted everything to size and welded it together, and then had a friend powder-coat it.
