Just want someone to agree with my thinking on this as i think its the actual antenna in the boot that is the problem now.
So i ran another cable from the HU to the antenna in the boot and no difference.
Then tried a normal car aerial i had in the HU and it picked up radio no probs.
Then i wired in same old car aerial into the cable going to the HU from the antenna (in the boot) and radio worked.
So i dont think its the cable, and as such must surely be the antenna in the boot?
DOnt want to buy a new antenna if i'm wrong of course!
Also what are the other 2 connectors on the unit, black one i imagine would be ground?
