what mount

[ashtrans]

Hi all,

just got a new 1200GS last week, only 21 miles on it !

I can't decide if I am better getting the genuine Nav IV bracket which has the 4 buttons but is not locking or the Locking V 2.0 mount from TT :

do I need the buttons on the genuine Nav IV or shall I get the cheaper 660 and locking bracket ?

thanks for any advise,

Dave
