Have been using the Visee0 in this car since purchase nearly 5 years ago with absolutely no problems.
In that time, I've used a Samsung Note 2, a Nokia Windows phone, and now a Samsung Note 3.
Until fairly recently, all has been flawless. But since replacing both batteries, the following happens:
Start car. After a seemingly random time, but usually under a minute, the radio mutes and the Audio 20 displays CALL. The phone is meanwhile doing nothing but sitting in its holder. A press of the 'end call' button restores normality. Another random interval, and repeat. No further problems until the next car restart.
The phone firmware has not changed during this time, so I'm wondering if I've upset the car Bluetooth system somehow?
Your thoughts appreciated.
 
Sounds like something on the handset is activating the HFP profile - Google maps can do this.
Might be worth terminating all running apps on the phone and trying again.
 
So which app is causing it?
