Hi,
I Have Nokia CK-300 installed in my ford focus 2008 (Radio CD 6000). Every time, when I listen music from my phone (nokia e51) through nokia ck-300 (via bluetooth A2DP) i have the same problem. When someone call's me radio switch to mute only for less than a second, and after that radio is again in Aux mode. When I stop the music, and someone calls everything is fine. I have the same problem with my other phone - blackberry 8520.
Please help
