Programming the SWI-X to control the new aftermarket head unit: First check that the IR remote that was supplied with the new head unit works properly. If the remote does not properly control the head unit, the interface cannot be programmed. Weak batteries in the remote may cause programming errors, even if the remote seems to operate the stereo properly.

The SW1.X must be programmed with a version number before you can access these programming steps. If it is not already programmed with a version number, go to step A in the previous section.

1) Turn on the ignition to supply power to the SWI-X. The SWI-X will flash the right LED (x) amount of times telling you what 'Version Number' it is programmed with. If the 'Version Number' is 10 or greater, the left LED will flash for the tens place and the right LED will flash for the ones place. If the LED does not flash, you will have to go to step A in the previous section.

If you are programming for Version 4 do steps 2.0 to 2.4. All other versions go to step 3.

2.0) Press the 'Program Mode' button to enter Heater/Air control programming mode. Release the program button when left LED light comes on. 2.1) Press and hold the TEMP UP steering wheel function button. When the left LED turns off release the steering wheel button.

2.2) The left LED will turn on again, press and hold the TEMP DOWN steering wheel function button. When the left LED turns off release the steering wheel button.

2.3) If the vehicle has FAN UP and FAN DOWN buttons, repeat steps 2.1 and 2.2 above but substitute the TEMP buttons with FAN UP and FAN DOWN buttons. After the fourth button for the Heater/Air controls is programmed, the left LED will flash once and then stay on to indicate it is ready to "learn" the radio functions. Go to step 4.

2.4) If the vehicle does not have FAN speed buttons, press the "Program Mode" button on the SWI-X. This will cause the interface to move to the radio function program mode. The left LED will flash once and then stay on to indicate it is ready to "learn" the radio functions. Go to step 4.

3) Press the 'Program Mode' button to enter radio command programming mode. Release the program button when left LED light comes on.

4) Within 10 seconds, press and hold one of the steering wheel function buttons. Continue to hold the steering wheel button until the left LED turns off. Release the steering wheel button and the right LED will turn on.

5) Hold the stereo's IR remote control 3-4" from the 'IR input' port on the side of the SWI-X and press the corresponding function button. Continue to hold the remote's button until the right LED turns off. Release the button and the left LED will turn on. Note: If the IR remote does not have a function that the steering wheel button has, you may assign any other IR command to that steering wheel button.

6) Repeat steps 4 and 5 until all radio steering wheel functions are programmed.

7) When programming is complete, wait 7 seconds and both LED's will flash 3 times. This indicates an automatic program exit. Do not stop more than 7 seconds while programming or there will be an automatic program exit and you will have to start over at step number 1 above. Do not turn off ignition before the automatic exit or you will be required to start over at step 1 above.

Testing the SWl-X

Test the SWI-X by holding it's IR LED (Blue LED on the end of 4' lead) close to the stereo and verify that it works properly. Experiment with various locations for the IR LED. Try along the top front and lor bottom of the stereo as well as it's sides. You can also try behind the dome light lens. The IR LED can be replaced with most common IR LED, like Radio Shack's # 276-143. The longest lead of the IR LED connects to the red wire of the 4' cable and the short lead of the IR LED connects to the black wire of the 4' cable.

¹The SWI-X will only work with remotes that use a J8 kHz to 40 kHz carrier frequency. Please consult with the owner's manual or manufacture of the device to determine if the remote is compatible with the SWI-X. Please check Version Chart for known units that are not compatible with the SW1-X. 

²Because of the different types of serial data baud rates from the steering whee/ buttons and the different types of IR remote data pattern, some stereos may respond very well, while others may not. You may try programming in 'Extended /R Mode' or in 'Standard IR Mode'. This mayor may not help in response from the stereo,
