Rds

Hi All i am a new member and own a 2012 X3, i am having trouble with the radio not holding channels and the RDS appears not to work, i can drive one end of the country to the other and the radio whilst it seems its attempting to scan for a stronger station just doesn't lock on.

Stations that are stored have awful hissing and interruption on them with real hissing on the sss sounds. I stand this next to my Golf gti on the drive both on the same station, the golf is perfect the X3 awful, BMW (up there own backside jumped up twelve year old's) refuse to accept there is a problem , initially blaming me saying i hadn't switched it on.

Has anyone experienced this, is it a known issue does anyone know of a fix please?

Cheers

Keith
