Hi guys,
This is the second part of an on-going saga!
I manged to get my Blaupunkt Essen to work in my Mark 2 Jetta after buying an ISO adapter - thanks to a couple of you guys's suggestions!
The thing is, now the illumination won't go out on the headunit at all - whether the key is in the ignition or not.
I have just noticed that the exisiting car loom is like this:
live not used power antenae [i think - yellow and white?]
earth illumination not used
and the new iso adapter feeds an ignition live line AND a constant 12v battery live into the live on the loom? i have also [stupidly!] cut the illumination wire to see if that did anything. it did not.
Please, if you can, help me. I'm getting remarkably down about this!

Cheers,
Si.
