Hello, I recently changed the stock radio and installed a double din, got the special antenna adapter but I need to find out what the factory wire for turning on the FM Antenna is, since the fm signal is really low. Can anyone help me please with a Wiring Diagram. Thank you JJB218

How do I test the radio antennae boosters my radio reception is terrible! I just bought a 2000 disco 2 and my radio reception is terrible. I changed head units over to a Sony (a good unit) thinking that would solve the problem. It didn't. I'm not receiving any AM stations at all. Even known...
