While the screen size is the same as my Go Cruise the new one is slightly larger. I temporarily spaced out the old ball mount with washers, I will make an alloy spacer later, I also filed out the ball cup to allow it to tilt back a bit more. Due to a slight discrepancy in voltages I replaced the wire to the unit, instead of using the old one which did fit. I am happy with the fit, although due to it's larger size I have had to also angle it in slightly. The navigation program is a lot easier to use than my old one it is intuitive and works out what you are typing in. The old one required you to type in every letter. The keys are large and reasonably easy to use with summer gloves, there is however a stylus which clips to the back of the mount, but requires you to remove your gloves to get it out of it's clip, sort of defeats the purpose. I used to hang a small rubber tipped stylus off the kill switch. Even though it used to get pinched all the time when I failed to remove it, when parked I will probably go back to this. It has heaps of extra features calendar, unit convertor, calculator, trip monitor, fuel consumption monitor, music player, picture viewer, sunrise & sunset, clothing sizes, Ebook, video viewer, photo viewer, and five games. How you are supposed to read a book, play games and view videos while riding has got me beat, maybe the Chinese are better at multi tasking. The GS has two ways of talking to you, blue tooth or FM, at the moment I am going to use FM. Tomorrow I am going for a ride to see how up to date the Mapping is.
