after market audio ???
 

Hi there,
Can anyone help me, I have purchased a XTRONS DVD system and cant seem to get it working with the ISO lead PC-75-2 checked the lead on the net and its one that everyone is recommending.
I have tried the system in my Citroen van so I know it works.
I have checked with a meter so I know that I have 12v switched and permanent live to the XTRONS DVD?? Off the harness side there is a black wire it has no voltage or doesn't bell down to neg??? how ever this does not connect through the new ISO lead?? what does it do and where does it need to go and does it need to be connected?????
I think it maybe a negative issue??
Help me please it's driving me mad (and the wife)
:eek:
