The conversion plug your on about Daz.....when i brought one for my cavalier i later found out all i needed todo was swap the red wire and the yellow wire, so i was miffed at spedning £10 on it! lol

Moonie.......what colour wires would need swaping around then?
And how do you tell if they need swaping? Isit if the radio works all the time and doesnt remeber any settings?
