Tried searching for similar issues but to no avail, just took home a new C300 that i'm loving but I'm having some major bluetooth connectivity issues with my iPhone 6(AT&T). The issues seem to happen randomly (sometime's it works flawless, other times not) but the phone constantly connects/disconnects from command during calls(on the command screen it flashes "CALL ENDED") while the call is still ongoing (just can't hear it via the command system). I've also noticed that if I try to stream music or make a call within the first minute of the car being on, that it sometime's results on the whole system making no noise [stereo, navigation etc.] . Its almost as if I trigger SIRI but its stuck indefinitely. Lastly, I've noticed some major issues with it picking up on calls that are in progress when I start the call (something that happens frequently to me). Anyone else have any ideas/tips? It's been a huge problem for me in this first week of owning the car.
