[V8] Radio code remembered by car?

[Tony and Lillie]

Only in 2001 and newer ones are the codes remembered. On that car, it will 
loose it's memory. Which is better than me, I've lost my mind!!

If you pull the radio out, you may find the sticker on it with the code. If 
not, you will have to write down the # on the radio and take it to the local 
dealer for the code.
