No advertisement, but since there was some communication about several options to control MRA using buttons on the handle bars and/or using the BMW wonder wheel, I thought the following might be if interest to MRA users.
It seems there is a Bluetooth module which (for now) connects to Android and makes it possible to use the wonderwheel for zooming in apps. This is what I missed the most using MRA instead of Navigator. It can be extended with a group of buttons to enhance the functionality.
I saw a price of £220 incl shipping.
Might be sounding like a lot, but development is never cheap and always more time consuming than expected. The parts look sturdy imho.
@MRA: Give it a go?
