Guida all'installazione

Precauzioni di sicurezza

Before beginning any installation, always disconnect the negative terminal of your vehicle's battery to prevent electrical shorts and damage.

This image shows the compact black Crux SOCGM-17 interface module, which is central to retaining factory features.

Collegamenti elettrici

The Crux SOCGM-17 includes all necessary harnesses for integration. Match the wires from the aftermarket radio harness to the corresponding wires on the Crux interface harness. Use appropriate connectors (e.g., splice connectors, solder and heat shrink) for secure and reliable connections.

This image displays the multi-colored wiring harness included with the Crux SOCGM-17, featuring a gray vehicle connector on one end and individual wires for connecting to an aftermarket radio on the other.

Connect the main vehicle harness from the Crux interface to the vehicle's factory wiring.
Connect the aftermarket radio harness to your new head unit.
Ensure all speaker wires, power wires (constant 12V, accessory 12V), ground, and illumination wires are correctly matched and connected.
Some wires, such as amplifier turn-on, parking brake sense, or steering wheel control connections, may require specific routing or additional connections depending on your aftermarket radio and vehicle configuration. Consult your aftermarket radio's manual for these specific connections.

Passaggi finali

Once all wiring connections are made and secured, carefully mount the aftermarket radio into the dashboard. Reconnect the negative terminal of the vehicle's battery.

Prova

Turn on the vehicle's ignition and power on the aftermarket radio. Verify that the radio functions correctly, including audio output, power on/off with ignition, and the retention of factory chimes. Test all vehicle functions that rely on the factory radio, such as door chimes, seatbelt warnings, and turn signal sounds.

Caratteristiche di funzionamento

Potenza accessoria trattenuta (RAP)

The SOCGM-17 provides a 12-volt accessory output that includes Retained Accessory Power (RAP). This feature keeps the aftermarket radio powered after the vehicle's ignition is turned off, until the driver's door is opened or the OEM timer ends, whichever occurs first.

Factory Chimes

This interface retains factory safety and warning chimes, ensuring that important vehicle alerts are still audible after the installation of an aftermarket radio.

Uscita di illuminazione

The module provides an illumination output, allowing the aftermarket radio's lighting to synchronize with the vehicle's dashboard illumination.

Risoluzione dei problemi

Nessuna alimentazione alla radio: Check all power and ground connections. Ensure the vehicle's battery is fully charged and properly connected. Verify the accessory wire is receiving power when the ignition is on.
Nessun suono: Confirm all speaker wires are correctly connected and not shorted. Check the amplifier turn-on wire if your vehicle has a factory amplified system. Ensure the aftermarket radio's volume is up and not muted.
Chimes Not Working: Double-check the connections related to the chime module. Ensure the interface module is receiving proper power.
Comandi al volante non funzionanti: If your aftermarket radio supports steering wheel controls and you have connected the appropriate wires, refer to your radio's manual for programming instructions.
