I hope that this is still on topic.
Has anyone successfully paired a Cardo G4 (or Schuberth SRC; same animal) with the K1600 and then paired a passenger helmet with the rider helmet? BMW has a sheet with a BT compatibility table that states that (paraphrasing) although the manufacturer states that this is possible, it will not work on the K1600.
I have decided that I like the Cardo system better since it uses the 100mW standard rather than the 2.5mW standard and will actually be available in the US before my first long trip in June. The only thing, in theory, that you would lose over the BMW system is the right grip volume control and simultaneous streaming of music from the bike to the passenger helmet. However, if BMW is correct that you cannot pair a Q4 (or SRC) to the bike and then pair another helmet to the Q4 (even though the Cardo is supposed to support this function ), then that's a problem.
So, in a nutshell, has anyone tried to use two Schuberth or Cardo systems on the bike yet? Specifically, one paired to the bike and a second paired to the rider's helmet?
Thanks in advance!
