Your Volvo radio may not work after the battery has been disconnected. You may see OFF or CODE in the display.
Most Volvos have a radio code to prevent theft. This code usually is a 4 digit code that should be stored in a safe place at all times! When the battery dies you will need this code to make the radio play again, but sometimes the radio will go into lock out mode and say "OFF." The only way to get by this so that "CODE" is displayed again, is to turn your switch to the 2nd position on the key switch and let set for 2-3 hours until it comes up.
Once it has been reset you should be able to enter the code into the radio and should work. If you enter the code incorrectly it will say "RPT" and you get another chance to enter it in, but if you enter it incorrectly three times it will go back into lock-out mode and say "OFF" and you will have to restart the entire process.
If you do not have the code, you will need proof of ownership. Your local Volvo dealership can look up your radio code to enter in at no charge.
Sometimes the radio in your Volvo may not be the original. To get the code, remove the radio. Get the serial numbers off the unit and the Volvo dealer can look it up that way. The dealerships should not charge for this service!
On rare occasion the car will have to be taken to them to inspect it to make sure you get the right code. This can cost from $10 to $100 depending on your dealership and what they want to charge.
ONCE YOU HAVE OBTAINED THE RADIO CODE MAKE COPIES OF IT AND PLACE IN DIFFERENT AREAS SO IF YOU CAN'T FIND ONE YOU WILL HAVE A BACK UP COPY. REASON WHY IS BECAUSE IF THE BATTERY GOES DEAD OR A TERMINAL IS DISCONNECTED YOU WILL NEED THE RADIO CODE FOR THE VEHICLE.
