The first cause I went with this considerably extra sophisticated strategy to securing the GPS is that I wished to have the ability to use the bike key to safe the GPS, slightly than needing a safety system which requires a separate device to launch the GPS (which I can assure I would misplace).

Quick ahead a bit: I changed the RS with a 2023 R1250RT, and wanted a technique to mount this locking GPS mount/XT2 association. Like many others, I finally went with the FMS mount and RFI defend: https://fmsaccessories.com/bmw-navigator-mount-2021-tft https://fmsaccessories.com/bmw-navigator-gps-rfi-shield

People have posted how one can’s on their GPS installations, and I am not meaning to duplicate their work right here. That stated, there are a pair particulars/variations in what I did which could be of use to others as they ponder their choices.

First, I can affirm what others have posted about with the ability to relocate the Sirius antenna with out touching the windshield. A phrase of warning: when you find yourself chopping the entrance fringe of the brand new mounting gap, make the outlet wider in very incremental steps till it’s simply barely broad sufficient! Whereas the entrance finish have to be broad sufficient to obtain the antenna’s underside hook (after all), there may be treasured little room to the perimeters — a hair too broad and gaps will seem on the sides of the antenna’s nostril.

As a result of the XT2 is greater than the BMW cradle (the XT2 being taller/wider than the XT and the Nav VI), I used Kristopher Ryan’s spacer block and XT2 locking arm equipment (kristopherryanrides@proton.me) to maneuver the XT2 out to clear the perimeters of the BMW cradle, as detailed within the RS thread. As well as, FMS mount comes with spacers that additional transfer the XT2 out to supply clearance for the BMW mount’s lock cylinder. As a result of I wished to reduce the quantity of XT2 overhang over the TFT, I shortened the FMS spacers till the lock cylinder boss simply kisses the FMS RFI defend face. A journey right now confirmed that the RFI defend remains to be efficient with the XT2 hanging out in entrance of the TFT.

As a result of I did not like the thought of simply wrapping the GPS cradle’s energy twine across the aspect of the FMS mount, I drilled a gap via the FMS RFI defend and mount plate, routed the twine via a grommet after which down via FMS’s provided pass-through.* This offers an uncluttered view from the rider’s seat:

*Seen cable litter is why I didn’t use the Italian 3DAM XT2 adapter I bought (quickly to go onto {the marketplace}).

A observe on the GPS mounting screws: They’re longer than these both BMW or FMS present, being M4 x 55mm (a size not carried in most native {hardware} shops; these had been sourced from McMaster-Carr). I *would possibly* have been in a position to get by with M4 x 50mm screws, however I am unsure they might have totally engaged the plastic within the nylock nuts. I’ll doubtless decide up some M4 x 50 screws sooner or later to search out out for positive, however the 55’s are ok for now. If the 50mm screws do not work, I will simply minimize off the surplus thread.

Hope that is useful to somebody!
