Here is, for anyone who is interested, my solution for fitting my old Zumo 550 to the new toilet GS 
Having bought the basic model without all the bits pre-installed that you get with the TE model, I first sourced BMW's own sat nav bar which cost about £35.

Then ordered these bits off fleebay for about £28.

Attached the Garmin mount to the new bracket:

And fitted everything to the BMW bar:


Appears to be good and solid and does not obscure the clocks


Will try it out for a while and if I like it will get round to plumbing in the power
