Can’t be bothered to read the 4 pages of replies but I have a gsxr 750 and use a yoke mount for my TomTom Urban rider.
Mount was made from http://www.telferizer.com/ - Great company, Bob is a very nice and friendly guy happy to help.
I use to use my phone but battery would run out for the rest of the day, when people called or things popped up it would cover the maps.
Tomtom urban rider you can hook up Bluetooth device. Touch screen is good! You have funky features like fastest route, shortest route, twisty roads, avoid motorways etc
Also have other features that I prob don’t use but will be useful for sure.
