The first purpose I went with this considerably extra difficult strategy to securing the GPS is that I wished to have the ability to use the bike key to safe the GPS, reasonably than needing a safety machine which requires a separate device to launch the GPS (which I can assure I might misplace).

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

Other people have posted find out how to’s on their GPS installations, and I am not desiring to duplicate their work right here. That mentioned, there are a pair particulars/variations in what I did which may be of use to others as they ponder their choices.

First, I can verify what others have posted about having the ability to relocate the Sirius antenna with out touching the windshield. A phrase of warning: if you end up slicing the entrance fringe of the brand new mounting gap, make the outlet wider in very incremental steps till it’s simply barely large sufficient! Whereas the entrance finish should be large sufficient to obtain the antenna’s underside hook (in fact), there may be treasured little room to the perimeters — a hair too large 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 package (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 offer clearance for the BMW mount’s lock cylinder. As a result of I wished to attenuate 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 trip at present 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 concept of simply wrapping the GPS cradle’s energy twine across the facet of the FMS mount, I drilled a gap by the FMS RFI defend and mount plate, routed the twine by a grommet after which down by FMS’s equipped pass-through. This supplies an uncluttered view from the rider’s seat:

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 capable of get by with M4 x 50mm screws, however I am undecided they’d 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 adequate for now. If the 50mm screws do not work, I am going to simply minimize off the surplus thread.

Hope that is useful to somebody!
