The instructions above are correct.
I looked in the Download Section, there used to be a scanned copy of the Owner's Manual there - it's gone. I looked in my archives & only found a copy of the Owner's Manual for '99 which doesn't show the Radio operation. I had scanned my copy of the Owner's Manual for 2000 but can't find it.
I PM'd Moncha about the missing files from the DL Section & will post a link when they are found/restored.
