How To Connect Bluetooth To Alpine Radio

Not no long ago, USB and AUX were the popular modes for connecting your phone to the car stereo.

But not anymore.

Bluetooth is now the preferred connectivity mode for car stereo connectivity, and for good reasons.

Not only is it more convenient than the USB and AUX connections but also allows you to make hands-free calls while driving.

In the past, Bluetooth technology had some reliability issues. But they’re all sorted now as the standard has matured enough.

How To Connect Bluetooth To Alpine Radio

As convenient as Bluetooth is, pairing your device for the first time can be a little lengthy.

That is why we’ll discuss the Bluetooth pairing procedure for some of the popular alpine car stereos.

How to Connect Bluetooth to Alpine CDE-172BT and UTE-73BT

  • Press and hold the ‘sleep’ button to put the radio in standby mode. It’s located in the bottom-left corner.
  • Now press and hold the ‘setup’ button.
  • You’ll get different options, with the first one being ‘Bluetooth’.
  • Press the volume knob to select this option.
  • Now, turn the knob until you see the ‘Pairing’ option on the screen. Press the knob again.
  • Turn the knob again and select the ‘Set Device’ option.
  • Now your car radio is available to be paired with other devices.
  • Open up your phone and turn on the Bluetooth. You should be able to see your radio model number in the nearby devices list.

  • Now you can use your car radio for music streaming and hands-free calling.

How to Delete Bluetooth Device From Alpine CDE-172BT

Some car radios allow you to store a limited number of paired devices. So in case you want to pair a new device with the car radio, you’ll have to delete one of the already-paired devices. Here’s how you can do it:

  • When in the Bluetooth menu, turn the knob until you see the ‘BT INITIAL‘ option on the screen. Select this option by pressing the knob.
  • This option will be ‘no’ by default. Turn the knob to change it to ‘Yes’.
  • It will completely wipe the Bluetooth memory, and now your paired device list will be blank.
