Thanks.
This is a European car and it uses different color wires.
I have gone through them all with my multi-meter and all seems fine. I assume this may be a fault with the new head unit as I re-installed the old one and that works perfectly.
I am trying to fit a Pure HS260DBi DAB Headunit in a Peugeot 206.
Rewired it and checked the live and it seems steady but when I turn it on the screen flickers on and off rapidly.
Does anyone know why this is happening and how I can solve it?
Thanks!
