Google NOW Causing problems with audio on Bluetooth car connection

[Brian Hunt4]

My Huawei P7 Android Vers 4.4.2 will not allow conversation when connected to the Premium sound system in my 2009 Australian Ford Falcon. The phone was working as expected till Google now was installed. Before The Huawei P7 I used a Samsung Galaxy S3 GT-I9100 4.1.2 which worked well. I initially put this down to the Build date of the Huawei v's the 2009 car and perhaps Blue tooth module incompatibility. I replaces the bluetooth control in the car to one supporting V4 bluetooth. The result, no difference for the Huawei, and the Old Samsung still worked fine. I looked at the difference in installed apps on the phones and it came down to Google Now. I uninstalled Google Now from the Huawei, and every thing worked again. Today, while using the Google Driving app, I found ,under settings,some controls for Google Now I selected "play voice over Bluetooth" and "play voice during phone calls". After that , bluetooth voice has not worked, nor has their been a dialing sound. The car system recognizes that the call has been answered, but neither party can hear anything
