ne one with ne sorta advice muchly appreciated

Not sure about the headlight prob but did you use the earth wire from the stock HU? If you did you need to earth the new HU directly to the chassis.. this will fix the turning on/off prob when you crank it.
Check out Head Unit Cut Outs? for a few notes and tips on how to do it

run a new feed, sometimes earthing or too much draw may cause a interference with your lights im guessing there on the same circuit or someting is touching. Try a new feed and ground point that may help you

thanx we end up disconnecting the cigarette lighter and runnin the active and earth of of that so the whole time the two probs were caused by a bad earth thanx for ur help

yes, you could say it was a bad earth.. the earth issue being the fact that it was actually an llumination wire. When you switched on your headlights the earth wire suddenly became an active 12Volts wire
