standard headunit - fine
then replaced it with a sony head unit - was fine, couldnt get the best signal but didnt have a pc5-90 signal splitter so i think that was the reason.
then replaced with a boss bv9150- unable to get a decent signal
thought it was the head unit so finaly found my standard head unit and tried that again, unable to get a signal so i think it may be something to do with the cars antenna circuit.
what parts are there that could have gone to cause me to get such rubish signal when i changed the head unit? and is there any easy way to test ? cheers
