PROGRAMMING THE AXDIS-GMLN30
For the steps below, the L.E.D. located inside the interface can only be seen while active. The
interface does not need to be opened to see the L.E.D.
• Start the vehicle.
• Connect the AXDIS-GMLN30 harness to the wiring harness in the vehicle.
• The L.E.D. will initially turn on solid Green, then turn off for a few seconds while it auto
detects the radio installed.
• The L.E.D. will then flash Red up to (18) times indicating which radio is connected to the interface,
and then turn off for a couple of seconds. Pay close attention to how many Red flashes there
are. This will help in troubleshooting, if need be. Refer to the L.E.D. feedback section for more
information.
• After a couple seconds the L.E.D. will turn on solid Red while the interface auto detects
the vehicle. The radio will shut off at this point. This process should take 5 to 30 seconds.
• Once the vehicle has been auto detected by the interface, the L.E.D. will turn on solid
Green, and the radio will come back on, indicating programming was successful.
• Test all functions of the installation for proper operation, before reassembling the dash. If
the interface fails to function, refer to Resetting the AXDIS-GMLN30.
Note: The L.E.D. will turn on solid Green for a moment, and then turn off under normal
operation after the key has been cycled.

STEERING WHEEL CONTROL SETTINGS
L.E.D. feedback
The (18) Red L.E.D. flashes represent what brand radio the AXDIS-GMLN30 believes it is
connected to. Each flash represents a different radio manufacturer. For example, if you are
installing a JVC radio, the AXDIS-GMLN30 will flash (5) times. Following is a legend that
dictates which manufacturer corresponds to which flash.
L.E.D. feedback legend
* Note: If the AXDIS-GMLN30 flashes Red (7) times, and you do not have an Alpine radio connected
to it, that means the AXDIS-GMLN30 does not detect a radio connected it. Verify that the 3.5mm
jack is connected to the correct steering wheel jack/wire in the radio.
** Note: Part number AXSWCH-PAR is required (sold separately). Also, the Parrot radio must be
updated to rev. 2.1.4 or higher through www.parrot.com.
† Note: If you have a Clarion radio and the steering wheel controls do not work, change the radio
type to the other Clarion radio type; same for Eclipse. The following section explains how to do this.
‡ Note: If you have a Kenwood radio and the L.E.D. feedback comes back as showing as a JVC radio,
change the radio type to a Kenwood. The following section explains how to do this.
1 flash - Eclipse (Type 1) †
2 flashes - Kenwood ‡
3 flashes - Clarion (Type 1) †
4 flashes - Sony / Dual
5 flashes - JVC
6 flashes - Pioneer / Jensen
7 flashes - Alpine *
8 flashes - Visteon
9 flashes - Valor
10 flashes - Clarion (Type 2) †
11 flashes - Metra OE
12 flashes - Eclipse (Type 2) †
13 flashes - LG
14 flashes - Parrot **
15 flashes - XITE
16 flashes - Philips

Changing radio type
If the LED flashes do not match the radio you have connected, you must manually program
the AXDIS-GMLN30 to tell it what radio it is connected to.
1. After (3) seconds of turning the key on, press and hold the Volume-Down button on the
steering wheel until the L.E.D. in the AXDIS-GMLN30 goes solid.
2. Release the Volume-Down button; the L.E.D. will go out indicating we are now in Changing
Radio Type mode.
3. Refer to the Radio Legend to know which radio number you would like to have
programmed.
4. Press and hold the Volume-Up button until the L.E.D. goes solid, and then release. Repeat
this step for the desired radio number you have selected.
5. Once the desired radio number has been selected, press and hold the Volume-Down button
on the steering wheel until the L.E.D. goes solid. The L.E.D. will remain on for about (3)
seconds while it stores the new radio information.
6. Once the L.E.D. goes off, the Changing Radio Type mode will then end. You can now test the
steering control wheel controls.
Note: If at any time the user fails to press any button for a period longer than (10) seconds,
this process will abort.
Attention: The Axxess Updater App can also be used to program the following (3) sub-sections as
well, pending that the interface has been initialized and programmed.

Remapping the steering wheel control buttons
Let’s say you have AXDIS-GMLN30 initialized and you want to change the button assignment
for the steering wheel control buttons. For example, you would like Seek-Up to become
Mute. Follow the steps below to remap the steering wheel control buttons:
1. Ensure the AXDIS-GMLN30 is visible so you can see the L.E.D. flashes to confirm button
recognition.
Tip:
Turning the radio off is recommended.
2. Within the first twenty seconds of turning the ignition on, press and hold the Volume-Up
button on the steering wheel until the L.E.D. goes solid.
3. Release the Volume-Up button, the L.E.D. will then go out; The Volume-Up button has now
been programmed.
4. Follow the list in the Button Assignment Legend to reference the order in which the steering
wheel control buttons need to be programmed.
Note:
If the next function on the list is not on the steering wheel, press the Volume-Up
button for (1) second until the L.E.D. comes on, and then release the Volume-Up button. This
will tell the AXDIS-GMLN30 that this function is not available and it will move on to the next
function.
5. To complete the remapping process, press and hold the Volume-Up button on the steering
wheel until the L.E.D. in the AXDIS-GMLN30 goes out.

Dual assignment instructions (long button press)
The AXDIS-GMLN30 has the capability to assign (2) functions to a single button, except Volume-
Up and Volume-Down. Follow the steps below to program the button(s) to your liking .
Note: Seek-Up and Seek-Down come pre-programmed as Preset-Up and Preset-Down
for a long button press.
1. Turn on the ignition but do not start the vehicle.
2. Press and hold down the steering wheel control button that you want to assign a long press
function to for about (10) seconds, or until the L.E.D. flashes rapidly. At this point release the
button; the L.E.D. will then go solid.
3. Press and release the Volume-Up button the number of times corresponding to the new button
number selected. Refer to the Dual Assignment Legend. The L.E.D. will flash rapidly while the
Volume-Up button is being pressed, and then go back to a solid L.E.D. once released. Go to the
next step once the Volume-Up button has been pressed the desired number of times.
Caution: If more than (10) seconds elapses between pressing the Volume-Up button, this
procedure will abort, and the L.E.D. will go out.
4. To store the long press button in memory, press the button that you assigned a long press
button to (the button held down in Step 2). The L.E.D. will now go off indicating the new
information has been stored.
Note: These steps must be repeated for each button you would like to assign a dual
purpose feature to. To reset a button back to its default state, repeat Step 1, and then
press the Volume-Down button. The L.E.D. will go out, and the long press mapping for
that button will be erased.
