Having ridden it for a few times now and had a chance to play with some of the toys there are a couple of niggles with the TFT / App.
To get the Map to display on the TFT needs a WiFi connection. So what happens is you start the app, turn on the ignition (order doesn't matter), app connects to TFT via Bluetooth. Then you need to start Map Mode on the App, which pops up a 'Connected wants to connect to WiFi .....' message. Click OK to that, then plug the phone into the charge cable in the box, shut the lid and good to go. That's all fine, until you stop say for fuel. When you turn the ignition off, the WiFi disconnects. When you switch on again the App connects OK to Bluetooth, tries to restart Map Mode but sits there waiting for you to OK the 'Join WiFi message'. Net result is that you need to get the phone out , click Ok and put it back in again. As you can't open the fuel cap with the ignition on, just leaving it connected to refuel isn't an option.
The other thing is that you can't change the headset volume (Sena SRL2) with the multi-controller (aka Wonder Wheel). You can with BMW headsets, which are Sena rebadged, but apparently not with any 3rd party ones. Not the end of the world to press the button on the side of the helmet, but I've never found that very easy to find with gloves on.
On the plus side, it does work really well playing Media from the phone, Radio Fm & DAB, Telephone, Navigation all controlled with the WonderWheel.
