If it's a newer car they can only be erased with a scanner or computer. If its older you can purchase a time keeper for your radio. It plugs into your cigarette lighter and takes a 9 volt battery. Can be purchased at the auto parts stores or Walmart for just a few dollars.

This is fairly easy... however: DISCONNECT NEGATIVE TERMINAL FIRST!! # Make sure your car is off # Keep your oem head unit codes handy in case you need to reset it # Disconnect you're negative terminal (use a rubber coated socket wrench to loosen the screw holding it in, make sure you wrap it in a rag to avoid it touching any ground on your car, and tape it off or hold it somewhere) # Disconnect the positive terminal # Reconnect your positive terminal # Reconnect your negative terminal # Then secure your battery covers and start your car and you're done!!
