My daughter has just purchased a Ford Fiesta 1.25 Freedom Special Edition (07)as her first car. I have debonded the phones that were on the 6000cd, and paired our phones to it, but whilst we can hear the call clearly, the caller can't hear us. Both phones work perfectly in my husbands Audi TT. Any help would be fantastic. Phones are connected via bluetooth and showing on the 6000cd.
