List Of Tools Needed

  • ¼ inch ratchet with a 7mm socket and extension.
  • Flat blade pocket screwdriver
  • Trim tool kit (inexpensive and recommended to prevent damage to trim parts)

Removing The Radio

  1. Park the truck on a level surface and set the parking brake.
  2. Turn the ignition key to the “Run” position, but do not start the truck.
  3. Move the column gear shifter as far down as it will go. This will make it easier to remove the radio trim bezel.
  4. Grab the upper right corner of the trim bezel and pull gently until it releases.
  5. Continue pulling around the trim bezel until it is completely free. Use a plastic trim tool to assist, if needed.
  6. Disconnect the power outlet and traction light connectors along the bottom of the trim bezel. Use a small flat blade screwdriver to release the tabs on the connectors.
  7. On four-wheel drive vehicles only, disconnect the transfer case control knob on the left side of the trim bezel.
  8. Pull the trim bezel out completely and set aside.
  9. Move the gearshift lever back into the “Park” position and remove the ignition key.
  10. Remove the (2) 7mm screws on the climate control head with the ratchet and extension. Move the control head down, but leave it connected.
  11. Remove the (4) 7mm screws on the radio head unit with the ratchet and extension.
  12. Slide the radio out and disconnect all connectors from the back of the radio head unit.

Installing The Radio

Follow the removal steps in the reverse order to install the replacement radio head unit.

Verify that the radio and navigation system are functioning correctly after installation.
