Default [Q] Bluetooth in call volume very low

Hi all,

I have been suffering the following problem for several weeks already, I hope someone can help me to get it solved. I have a parrot bluetooth car kit installed in my car (mk6000 model) which is able to play music on stereo.

When I play music the volume level is pretty good, as good as when I use the speakers or wired headphones. However, the in call volume is extremely low, no matter if the Nexus was playing music right before the call or in stand-by (with wired headphones or no accessories in-call volume is fine). This also happens to both incoming and outgoing calls.

I have tried to unpair and then pair again the device but it is still the same. Also installed the Bluetooth Volume application with no luck. I have not checked with bluetooth headphones but I assume that I would get the same issue.

I am surprised that nobody posted this before (at least I could not find anything) and I am wondering if this is only happening to me.

Can anyone give me some advice?

Thanks!
