G'day, as the title I'm trying to unlocl my AUII Forte's cd player, it flashes "ERR". I was told by Tilford to turn the ignition to accessory for a few minutes and wait for that flashing ERR message to go away and input the code.

I tried that for bloody ages and nothing seemed to change, now I don't have the manual and I doubt Tilford have led me wrong, but unless the bloke at Tilfords definition of "a few minutes" is like half an hour I don't think it's right..

Anyone able to help me out?

if thats his defintion he would be correct. Most AU's are 30 minutes, some are even an hour.
