Ok, it seems the TuneIN MB app has difficulties to start when you have a certain (incompatible?) radio station pre-selected, that it tries to connect to while starting the MB App. Fiddled a bit, and finally managed to get in the TuneIN settings, choose another (HTTP) station, and it started working again. Still most (HTTPS) stations are not playable, but at least some of the streams can be listened again now. I really hope that MB and TuneIN give a decent upgrade to this app asap. That could be done OTA I assume or is a dealer visit required? (unbelievable how slow these kind of things go..........my friend has a new Tesla for 2 weeks now, and already got several major software upgrades, with not only bug fixes, but with added functionality!)
