Hi,
In my issues with eletrônics WD40 or contact cleaner does the job.
I’d try that even the handlebar central lock.

HI, there
Nice job.
Finally got it to work, but still ask me to join BMW WiFi every time I stop for gas or something else.
Am I missing something?

I`m intersted in this topic too.
My 10 years long BMW system 6 comm is asking for another one and I am on the fence wich way to go.
My wife's helmet and BMW comm is still perfect.

tks

A little bit late but same problem here.
Tried all of the suggestions. What solved the issue was to delete and download the maps.
Probably a bug from the last map update that came automatically.
