My 1" RAM mount has cracked, probably due to me over tightening the clamp to try and keep my Tom Tom Rider sat nav from moving around. I also use my iPhone 12 for sat nav occasionally in the M3W with a RAM X-Grip, this is lighter and doesn't bounce around as much as the Tom Tom Rider. The other advantage with the iPhone is that if there is a group of you, you can all use a common sat nav system such as Google maps to make things easier with planning routes.

I enquired with the original supplier of my RAM mount about getting a new 1" ball, no problem with that but he called me and asked if I was aware of the problems of using an iPhone mounted on "a motorcycle", specifically the deterioration to the camera optics from vibrations? I wasn't but have read a few bits about it and it does seem to be a problem for some.

Has anyone had these problems with mounting their iPhone to the vibrating M3W? It could be that bikes with high revving engines are the main problem, rather than the slower revving V-Twin? He recommends using a Quadlock vibration damper but I am not sure I want the Quadlock system on the back of my phone all the time for the few occasions I use it. Any info about iPhone camera problems and vibrations appreciated to judge if it really is a problem with the M3W.
