After I updated my MMI High system to the newest firmware and updated to the 2018 NA maps I just noticed that the Jukebox is greyed out. Can I fix it somehow possibly using the GEM. Or any other way. Also can I adjust how or where the suggested shifting in my manual transmission shows on the dash display? LOL I'm teaching my wonderful girlfriend how to drive a manual and it wants to shift around 2000 RPM . I'd like it to be closer to 2500 RPM. If not thanks for reading anyways. Just thought that there may be a setting in the GEM that i can adjust.
