I have the base radio in my car and it sounds great to me even with the top down. I was surprised to see it does not provide any information rearding the station and music being played like most modern car radios now have. My past 4 cars all had it and now I miss it. You here something new and you like it you know who the band is and the name of the sold. My Dodge truck has it but I guess that technology was not passed up to MB? Do any of the upgraded systems have it? I think it is standard equipment on a Hyundia or Kia but not on a MB?
