ADJUSTMENTS

Chime level adjustment:

1. With the vehicle on, turn it off and leave the keys in ignition. Open the driver’s door; chimes

will be heard.

2. Wait 10 seconds, and then with a small ﬂat-blade screwdriver, turn the potentiometer

clockwise to raise the chime level; counterclockwise to lower the chime level.

3. When the chime is at a desired level, remove the keys from the ignition. This will lock the

chime volume at its current level.

OnStar level adjustment:

1. Press the OnStar button to activate it.

2. While OnStar is speaking, press the VOLUME-UP or VOLUME-DOWN button on the steering

wheel to raise or lower the OnStar level.

3. If the vehicle doesn’t come equipped with steering wheel controls, locate the Black/Yellow

wire on the 3028 harness.

4. While OnStar is speaking, tap the Black/Yellow wire to ground. Once the OnStar level is set,

it will stay at that level until the Black/Yellow wire is tapped to ground again.

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.

1. Start 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 (21) 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.

3. 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.

4. 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.

Programming the climate display:

5. Ensure that the vehicle is still running.

6. Adjust the fan speed on the climate control all the way up, then all the way down.

7. Test all functions of the installation for proper operation, before reassembling the dash.

8. If the interface fails to function, refer to the Troubleshooting section.

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.
