Awesome....my plan is to make up the adaptor like you have and leave it permanently connected. If i have the opposite connector on my usb interface i can just plug it in as and when required without having to disconnect everything and without having to leave the interface connected up permanently.

Hoping it arrives tomorrow so i can get my nav running in english once cameras are turned off.
Can you have GB set as first and second language ie GB GB or does it have to be GB US?
