Diamond Audio MSHDHU9813RG Installation Guide | 1998-2013 Road Glide

Please follow these installation tips when you're ready to install your new 
Diamond Audio MSHDHU9813RG radio
in your 1998-2013 Harley-Davidson® Road Glide.


Tools Needed:
  • ½ inch wrench
  • T25 torx bit
  • 3/16-inch allen
  • Zip ties
  • Cutters
  • Fender cover
Step 1

Remove the outer fairing:
  • Cover the front fender with a fender cover.
  • Use a ½ inch wrench to remove the nuts that secure the turn signals from the inside of the forks.
  • Depress the tab and remove the turn signal wiring harness from each light.
  • Remove the six T25 bolts that secure the inner fairing.
    • 1 set towards the top of the inner fairing.
    • 1 set in the middle along the outside edge of the inner fairing.
    • 1 set at the bottom along the outside of the inner fairing.
  • Lift up and out on the outer fairing.
  • Unplug the headlight harness and set the outer fairing to the side.
Step 2

Removing the factory radio:
  • Disconnect all wiring harnesses from the back of the radio.
  • Remove the four 3/16 inch allen screws that secure the radio.
  • Remove the radio towards the gas tank.
Step 3

Installing your new Diamond Audio MSHDHU9813RG radio:
  • Insert the radio into the inner fairing.
  • Ensure that the four factory mounting holes are lined up and secure with the four 3/16th inch allen bolts.
  • Connect the harness to the back of the radio.
  • Insert the harness, swivel the locking tab until it clicks and locks into place.
  • Connect the AM/FM antenna to the radio.
  • Connect the provided microphone to the radio.
    • We recommend mounting the provided microphone to the top in the inner fairing just behind the windshield. This will give you the ability to use hands free calling and the placement will reduce wind noise as much as possible.
  • You have the option to mount the pre-connected USB where you prefer.
    • One recommend location inside the storage cubby on the right side of the inner fairing. This will require drilling a 1-inch hole in the back side of the cubby large enough to pass the USB wire through.
    • The USB wire comes with a grommet that will secure the USB in the hole.
Step 4

Test the function of the radio:
  • Turn the ignition to accessory and allow the unit to fully power on.
  • Select a local AM/FM station and check sound output on each speaker.
  • Connect your phone to the USB and check either Apple CarPlay or Android Auto function.
    • If you are using wired Apple CarPlay or Android Auto, please ensure that you are using a factory cable (the one from the phone manufacturer) or an Anker brand cable.
  • Check your handlebar controls to ensure proper function.
Step 5

Replacing the outer fairing:
  • Secure any loose wire with zip ties.
  • Connect the headlight harness.
  • Place the outer fairing back on the motorcycle ensuring that it is hanging on the factory support bracket.
  • Replace the six T25 bolts that secure the inner and outer fairing.
    • 1 set towards the top of the inner fairing.
    • 1 set in the middle along the outside edge of the inner fairing.
    • 1 set at the bottom along the outside of the inner fairing.
  • Reconnect the wiring harnesses for the turn signals.
  • Use a ½ inch wrench to replace the nuts that secure the turn signals from the inside of the forks.

Congratulations on installing your new
Diamond Audio Radio!
