Gents, just a word of caution. I had my Sena 10s, BMW Nav6 and my iPhone 6 perfectly working. Phone calls via NAV6 and Sena, audible warnings etc. all went well. The iOS 11 comes along and that was it with love, peace and happiness. It appears that the new bluetooth stack has a lot of issues for example it does not release a channel after using it and thereby blocks media or intercom. Took me a while to figure that out by disabling Smartlink traffic and safety cameras. With that all went back to normal. Any similar experiences in the esteemed forum membership?
