To clear all saved Bluetooth devices on a Pioneer AVH-120BT, open the Bluetooth settings on the receiver, select [Bluetooth Memory Clear], touch [Clear], and then touch [OK]. The owner’s manual’s Bluetooth settings section gives this sequence. If you only want to remove one phone and keep the others, delete that single device under [Connection] instead.

Clear the full Bluetooth memory

Use this route when you want every paired device removed from the receiver, for example before selling the unit or handing a vehicle to someone else.

  1. Press the unit’s control button as the manual’s Bluetooth instructions describe, then open the on-screen menu.
  2. Touch the two menu controls that lead to Bluetooth settings. The manual’s text extraction does not reliably name these icons, so follow the icon that is labelled or clearly marked as Bluetooth.
  3. In Bluetooth settings, select [Bluetooth Memory Clear].
  4. Touch [Clear].
  5. Touch [OK] to confirm.

The manual warns: “Never turn this product off and disconnect the device while the Bluetooth setting operation is being processed.” Wait until the operation finishes before powering down the receiver or unplugging the phone.

Delete one saved phone

If you only need to remove a single device, you do not have to wipe the whole list. Bluetooth settings include a [Connection] area that lets you connect, disconnect, or delete a registered device manually.

#1 Best Overall
Pioneer MVH-S110BT 1-Din Digital Media Car Stereo with Bluetooth
  • Seamless Bluetooth Connectivity: Car stereo with Bluetooth technology allows you to enjoy hands-free calling and high-quality wireless music streaming from your iPhone and Android devices.
  • Powerful, Clear Audio Performance: Equipped with a built-in MOSFET amplifier, this Pioneer car stereo delivers up to 50 watts per channel to four speakers for rich, dynamic sound across your entire vehicle.
  • High-Quality Music Playback via USB: Enjoy clear, detailed sound from your favorite tracks using the front USB input—compatible with FLAC, MP3, and WMA formats.
  • Compact 1-DIN Design: Single din radio is designed with a super-short chassis to make installation easy, even in vehicles with limited dash space, without compromising on performance.
  • Simple Sound Customization: Dedicated Direct EQ Keys let you adjust bass, treble, and balance settings on the Pioneer stereo to match your personal listening style.
  1. Open Bluetooth settings as in the steps above.
  2. Select [Connection].
  3. Find the registered device you want to remove and touch its delete control.

This is the better choice when other phones should stay paired, because it changes only the device you select.

Understand the three-device limit

The AVH-120BT can register up to three Bluetooth devices. If three are already paired and you try to add a fourth, the display shows [Memory Full]. The manual’s instruction is to delete a paired device before adding another, so the single-device route above is the usual fix. Clearing all memory also frees every slot at once.

Why the RESET button is not the same thing

The physical RESET button on the unit is a broader action. According to the owner’s manual, it returns settings and recorded contents to factory defaults, and some settings or contents may not reset. The manual also advises against pressing it while a device is connected.

For removing Bluetooth pairings, use the Bluetooth Memory Clear menu. Reserve RESET for cases where you want the receiver’s general settings reset as well.
