Hi, I am having problems with the radio reception; FM fine but AM/LW rubbish. Having just bought a '53 320i SE, I don't know where anything is (too tight to buy a workshop manual!). 1. Is anyone familiar with the problem? 2. Where is the ariel; been advised rear screen but unless part of the demister, not obviously there! 3. Is there a radio signal amp and if so where is it located? Thanks in advance for any help. Andy C
