Nah no more action on this.........tried a few other suggestions but nothing worked
Some1 suggested (on a different forum) that i needed to power my antenna which is in the rear window, did this and it still didn't work so basically gave up and dont even listen to the radio now
eventually i'm gonna get some nice big speakers & amp fitted so might get a pro to do it and see if they can sort out my radio reception!
also noticed some1 else posted a similar thread to this recently:
