Ive just bought a 2011 SE Tech with the Pioneer sat nav and whilst I prefer the look of the OEM one, I like the functionality of the Pioneer unit. Everything is good, except pairing my iPhone 5c. It pairs ok, streams music and makes phone calls, HOWEVER, when calls are answered, no-one can hear me! Ive tried my iPhone 5c which isn't listed as supported and an iPhone 4 which is listed as supported with the same result. The radio level stays the same when a call is made so I'm wondering could the hands free mic be the problem. Has anyone any ideas?
