Hello, i have just changed my headunit from the orginal one to a kenwood CD MP3 system, everything works fine apart from the radio i seem to only be able to pick up radio 1 i have checked the ariel adapter is connected and all is fine,

Any ideas,

Wesley

Could be the aerial unit itself! they are prone to go especially if the seal has a leak!

There is a white wire in the original connections which takes power (switched by the radio) to the antenna amplifier. I know the Blaupunkt connector I had missed this wire out. If it isn't connected just take a feed from the amplifier remote lead.
