Hi, This a general enquiry about radio reception. My previous 2006 320 cdi CLS could almost pick up the grass growing the radio reception was so good. I changed it for a 2008 CLS 63AMG which has a digital tv tuner and wonder if the radio is digital also. The reception is acceptable in and around the city but as soon as you stray far from the city the radio reception deteriorates to such an extent you just can't listen any longer. Is this common or do I have a problem with the car? Thanks.
