The CGRC CAN for the BMW 1600GT (build 2020) is not yet fully developed for older types of the 1600GT. I recommend Chigee (AIO-5 for BMW) to work together with BMW (software development) on the improvement of use of the “wonderwheel”. For instance: In order to scroll-down in the menu of the Chigee the wonderwheel must scroll-up. Further more: When the wonderwheel is used to scroll down or up, the onboard radio volume is also influenced by the wheel producing less or more sound on the onboard speakers or speakers in the helmet. In order to covert these inconveniences I recommend to improve the Chigee -software in cooperation with BMW. It is also a matter of safety to limit distraction using the wonderwheel with Chigee while riding. It should function more logical and less distractive. I really think the Chigee is on its way to “make life a ride” and not to end it through distraction.
