I have a '12 Subaru Outback 3.6 with H-K audio and ipod interface. I am unable to use Siri voice commands on my iphone 5s to make outgoing calls, and from what I've read, this has been an issue since the 4s's. The phone will actually understand me and dial, but the Bluetooth in the car disconnects the call before it can go through. (I am able to use the phone manually to dial, but that kind of defeats the purpose of hands-free.) I have tried everything I can find on the web, including deleting and re-pairing the phone, un-pairing the media player interface, rebooting my phone, turning Airplane mode on and off, etc. Please advise if there is a software or hardware update, or some other trick for me to try. The car is still under warranty (just under 35k miles). Thx in advance.
