socket

Can anyone confirm the following for me please regarding a Garmin Zumo 340LM 1 This will mount OK using the Yamaha GPS mount for the MT07 2 The headphone socket gives the turn directions through a set of headphone, or a suggestion for a cheap set of Bluetooth headphones that works with this...

Hi everybody, hope you are getting some riding in now that summer is here well by name anyway. The nut on the mounting pin on top end of the schock,is it 15mm.? looks as though it is stepped,Will an ordinary socket do the job? and any tips will be most welcome .regards Brianj.
