PROGRAMMING THE INTERFACE AND CLIMATE DISPLAY
Programming the interface:
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 7390 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.
Refer to “Steering Wheel Control Settings” for customizing the buttons, if so desired.
If the interface fails to function, refer to Resetting the interface.
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.
1. Secure the climate control assembly to the dash in reverse order of disassembly using the
factory screws.
2. Secure the radio assembly to the dash using the factory screws.
3. Reassemble the dash in reverse order of disassembly to complete the installation.
