To determine if your Pioneer DEH-S510BT needs a firmware update, you first need to check its current firmware version. Here’s how to do it:
- Start your vehicle's engine.
- If the audio source is on, press and hold the [SRC/OFF] button to turn the source off.
- Press and hold the [SRC/OFF] button again to bring up the Initial menu, then press the Multi Control to confirm your selection.
- Rotate the Multi Control until "SYSTEM UPDATE" is displayed, then press the Multi Control to confirm.
- Select "SYSTEM INFO" and confirm.
- On the "SYSTEM INFO" screen, you'll see the current firmware version. If the version number is 8.27 or higher, your Pioneer DEH-S510BT CD Receiver does not require a firmware update. If the version number is lower than 8.27, you should update the firmware by following the instructions in the device's manual. Always follow the steps precisely to ensure a successful update. If you have any trouble, Pioneer Customer Support is available to help.
