I have option 2 at the moment. Givi sat nav holder and a Garmin nuvi car sat nav which I power from the socket on the bike using an £11 adapter from Nippy Norman's. I could Bluetooth the sound but haven't.

Pros are it's cheap and I just grab it from the car.

The GS has bars that suits the Givi case. The socket is easily accessible.

Cons are it's hard to see in bright sunlight, you can't use a tank bag, if you forget the waterproof over cover it gets wet. Plus being a touch screen unit under a plastic cover you have to pull over and undo it all to press a button such as setting up a detour.

Fine for me as I don't use it often.
