My 2000 S70 still has the original battery which I want to replace. The owners manual says DO NOT DISCONNECT BATTERY WITHOUT CONSULTING DEALER. What will happen if I do. I do have the radio activation code. I expect it to run a bit erratically until the computer relearns thing, but will anything else other than losing the radio stations happen?

You will lose everything on your dash except gas gauge and temp gauge and your odometer will change to kilometers. I know because I did it and no one on this group or any Volvo forum I've been on knows what to do to fix it.
Your experience appears to be the exception, which is why I wonder if you have disconnected the battery and reconnected it again to get a "clean boot" of the computerized systems. Your symptoms are pretty typical for a "dirty boot" - a tentative connection that has caused a computer to go into a hung state. See
your call will be fine
