The "Tripper" is just a display - the navigation is done by your mobile phone & this connects to the "Tripper" display using Bluetooth & an RE app. The display shows when turns etc. are required, counting down to and changing colour as you approach the manoevere - seems less intrusive than full-on sat nav to me. I have seen suggested that the "Tripper" display will be available to retrofit.
The Meteor replaces the Indian market Thunderbird "cruiser" which didn't come to the UK. A replacement for the Classic & the Bullet based on the new platform is expected & I have seen one suggestion that this new 350 will be coming to Europe. Guess it will be down to how greedy MotoGB are WRT to pricing as to whether it will be attractive or not.
