I just purchased a 2011 R1200RT. I have successfully paired my Iphone to my Zumo and my Zumo to my Sena SMH10 so I can have phone, directions, MP3. I also tried to pair the BMW radio/sound system to the Zumo, but that did not work. I also tried pairing the Zumo to the headset and the radio to the headset, but that didn't work either. I can pair the BMW radio to the headset. It appears that either the Zumo/Iphone are paired to the headset, or the BMW radio is paired, but not both. Has anyone else had a similar experience? Any ideas?
