When I enter into the car it takes longer than usual until the mobile phone has connected to the car radio. If I telephone is lost in the middle of the conversation the Bluetooth connection and I hear then no longer my call partner. The telephone conversation continues however in the time. After a while, the connection between both devices is established again. Otherwise, the custom ROM is not bad.
