Hello everyone.
So, my first task with my new (to me) XR is to get rid of the sat nav preparation bracket. My plan is to replace this with a Quadlock wireless charging head which I will attach to the metal bar that runs through the sat nav bracket.
It was straightforward enough to take the nav mount off the metal bar and replace the bar in the bracket attached to the handlebars.
It's the other end of the cable that has me slightly confused !
I was going to order the Nippy Normans BMW harness to female USB socket (
https://www.nippynormans.com/ram-mounts-and-more/bmw-harness-to-female-usb-socket) and simply plug that into the socket down by the back of the RHS headlight.
However, it turns out that the other end of the power cable for the sat nav does not end in a plug; it's hard wired into the back of the accessory socket. Another cable is plugged into the socket itself.
Some snaps to explain what I mean...
In this pic you can see the socket as I found it.

There is a silver-grey cable which is plugged into the socket. But the power to the sat nav is the black cable that runs beneath it.
In this pic I have unplugged the silver grey cable.

And in the pic below you should be able to see the sat nat power cable running into the back of the accessory socket. As far as I can see, it can't be unplugged.

So, a couple of questions :
- I can't work out what that silver grey cable is connected to but I am guessing it's nothing to do with the sat nav and so needs to remain in the socket - yes ?
- If that's the case then I guess I can't use that Nippy Norman's solution as there is nowhere to plug it in (at least at the front of the bike)...
- I have read on here that some of you have used the existing power cable (which I was kind of hoping to keep intact) by just chopping off the nav mount and soldering / shinkwrapping on a USB connector. I don't really want to do this, not least because I don't have a garage and soldering standing out in the street is not straightforward - but it feels like it might be the only option
- unless there's some kind of splitter out there which will allow two accessories to plug into the same socket - any suggestions ?
Thanks for any guidance !
