This post is an answer for a request to show details of the way I mounted the GPS in my Quest.
I already had a RAM in Quest 215 mounted on the wheel-chest. unfortunately I wasn’t able to see it when I was using the tour-cap. So I decided to mount it in Quest 552 on the handlebars. I used a simple iron strip, bend it a bit in the right angle and used a hose clamp to mount it on the handlebar.
By moving the handlebar around I can manoeuvre it in a place that reflection on the gps-screen does not occur. This manoeuvring doesn’t influence the steering.
