Hi all, I've recently bought DSX - S300BTX car unit, and I need your suggestion. I'm having troubles with Handsfree Bluetooth Phone Call function . Actually, when I make or receive a call using my iPhone 4S (iOS6), I have no audio from car speakers, if I'm in "Bluetooth Audio", "Bluetooth Phone", or "USB mode". But everything is fine if in "Tuner" mode. The "handsfree on" message is correctly displayed.

I've tried the "call transfer" button, as suggested in a sony FAQ, but no luck. Can be a defective unit?

Thanks,

Andrea
