Great product, fixes strange bmw omission.
For some reason, bmw eliminated the canbus port on the R Nine T’s in recent years. Mines a ‘22 standard model. This product allows you to add the port back, in my case to use with the Optimate 4 trickle charger, and also leave the USB port alive so you can still charge accessories, phones, etc. The install is easy and leaves a factory looking finish. My Optimate 4 Canbus edition plugs right in and charges perfectly. No idea why bmw couldn’t do this from the factory, but this is a great product that gets you the best of both worlds: usb charger and factory appearing canbus port. Highly recommend.
