I had to change the battery on my vectra, with a standard radio and 10 loader cd player, and checked that i had the code before disconecting the battery, only when i connect it all up, i find the code only restarts the radio not the cd player which has a seperate code which...........yep youve guessed it I dont have, so wheres the cheapest place to get the code from and how much if anyone here has any advice,,, much appreciated simon
