Just taken delivery of a new 1200gs rallye with tft I have a nav v fitted to the bike from my last bike but it appears the wheel you use on the handlebars to scroll through the menu's does not work like it did on my previous bmw, any ideas also I am pretty sure my tft has not had the update as my miles to empty will not go any higher than 161 miles software showing on the tft 001-011-081. I am going to have to find a problem to get the dealer to do the update ?
