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!!
Disconnect the battery from the car for about 10 minutes; If that doesn't work take it to the shop and have the codes read and reset.
