Now, as far as your radio problem goes, it sounds like it's time for a new one.
The factory head units only last so long and yours is now 16 years old - assuming it's still the original factory head unit.
I deep-sixed mine a long time ago (after going through 3 different factory head units) & upgraded to a Pioneer AVH-X490BS CD/DVD RDS AV head unit, with Sirius XM Receiver.
One of the best upgrades I've made to date and I've done a boat-load of them.
