DIP SWITCH SETTINGS:

AFTERMARKET RADIO DIP SWITCH SETTINGS:

NOTE: For Atoto, Blaupunkt, Dual, Farenheit, Power Acoustik, Soundstream, and most off-brand radios, check the aftermarket radio's manual to see if the SWC buttons need to be programmed.

4-PIN SWC CABLE

Use the proper 3.5MM to 4-Pin SWC cable for the aftermarket radio you are using.

OPTION A is used for ALPINE, CLARION, JVC, and KENWOOD units (Blue/Yellow wire is attached) OPTION B is used for ATOTO, BLAUPUNKT, BOSS, DUAL, FARENHEIT, JENSEN, POWER ACOUSTIK, PIONEER, SONY, SOUNDSTREAM and Most Off-Brand Radios.

NOTE: Cap or insulate the 3.5mm plug or Blue/Yellow wire if not being used.

For aftermarket radios that have wires for SWC connections, cut off the 3.5mm plug on the Crux SWC Cable (option B) and connect the SWC wires as follows:

SHIELD to SWC Ground

Note that there are some radios that only have SWC1 and SWC2, in this case “shield” does not need to be connected.

SELECTING THE AUDIO SYSTEM:

If the vehicle is equipped with an amplified audio system, the SWRGM-47 has a built-in audio level adaptor that outputs the proper audio level from the aftermarket radio to the factory amplifier. To use this feature, plug in the male 8-pin connector on the SWRGM-47 harness to the GRAY female 8-pin connector on the SWRGM-47 module. The module is also labeled "Bose" and "Non Bose" to avoid confusion. (see picture below)

If the vehicle is NOT equipped with a factory amplified system, plug in the male 8-pin connector to the BLACK female 8-pin on the SWRGM-47 module.

BACKUP CAMERA TROUBLESHOOTING:

Problem: The aftermarket radio does not show the reverse camera image when the vehicle is in reverse.

NOTE: Some vehicles, the reverse camera image is first displayed on the radio display before appearing on the radio.

Solution: Connect the camera input and output wires together using the radio display harness.

1. Locate pins 5, 6, 7, and 8 on the Gray 20-pin harness situated at the rear of the radio display (refer to Figure 1).
2. Cut the wires connected to pins 5, 6, 7, and 8 near the connector, while ensuring sufficient wire length remains for potential reconnection if the original radio is reinstalled.
3. The loose, severed wires originating from the connector are not required. However, the remaining cut wires within the harness must be interconnected as follows (see Figure 2):
4. Join Pin 5 to Pin 7.
5. Then also join Pin 6 to Pin 8.
6. Establish a connection between the Reverse Camera output connector of the SWRGM-47 HAR and the Reverse Camera input on the aftermarket radio
