Step 2

If your motorcycle has the factory Boom Audio system or is a CVO do not go any further without reading the steps below:

To locate your BIN code in your factory GT radio do the following:
  1. Power on your bike to accessory power
  2. When the "Warning" screen appears on your head unit you're going to cover the mute and power button (lower right hand corner of the screen) with your thumb until the service menu appears - it'll take 5 seconds or so.
  3. When the service menu appears, you're going to select: Audio --> EQ --> then select the "i" icon for information.
  4. At this point you'll see something on the screen such as: Current EQ version: 17_OFF.bin Load new EQ?
For this example, you'd load your BIN number as 017 into the Diamond Audio radio following the instructions below.

Before proceeding to the next step below, make sure to hit "No" on the screen.

To locate your BIN code in your factory GTS radio do the following:
  1. Hold your finger on the power/mute button while turning on ignition
  2. Hold the power/mute button until the head unit powers up into the service menu - it'll take about 10 seconds.
  3. When the service menu appears, release your finger
  4. Press Audio
  5. Press EQ
  6. Press the "i" button on the right hand side of the screen
  7. Then, your current BIN number will be displayed. It will say something like: Current EQ version: 178_OFF.bin. Load new EQ?
For this example, you'd load your BIN number as 178 into the Diamond Audio radio following the instructions below.

Before proceeding to the next step below, make sure to hit "No" on the screen.

Now, when you have your new Diamond MSHD14 plugged into the bike and powered up, do the following:
  1. Go to the main screen
  2. Select "Motorcycle Info" icon
  3. Press the Gear/Settings icon (also known as Setup)
  4. Press "Vehicle Settings"
  5. Press "Amp Settings"
  6. Press "Audio System"
  7. This is the step you'll enter your BIN number found above. Tap each number the number of times for each number. So, if you wanted the code 178, you'd tap the first box 1 time, the second box 7 times and the third box 8 times. Then, hit okay.
  8. Then it will ask you to confirm your selection and then select yes.

Step 5
