Having used a Nautilus on my previous two boxers, I wanted one on my new bike as well. Reading through the search results here I realised that things might be a bit more difficult than on the R850R.
Anyway, I ordered a CANBUS link from Nippy Norman and set to work with the Nautilus off my old bike. Steptoe had done a great job wiring up the relay; I simply unplugged everything and reconnected the OEM horn.
Looking for a suitable mounting position for the Nautilus on the GS I decided to check whether the Stebel would in fact fit to the OEM mounting bracket. Surprise: it does! I changed the angle a tiny bit but didn't have to bend anything. Clearance is A-OK: nothing touches, nothing fouls.
The OEM metal mounting strip is a bit wobbly but in six weeks and 1,500m nothing has moved. I might fabricate a stronger one when I find the time.
The only tricky bit was the CANBUS connection to the horn: it IS polarity sensitive, so if it only quacks like a sick duck rather than sounding like a fog horn, the wires to the horn need to be swapped. No prizes for guessing how I know that...
I used a 20amp fuse and fixed the relay to the frame with a cable tie. No wires were cut and I used connectors where necessary so the bike can easily be returned to its original condition.

Hope this helps!
Ride safe,
