CONNECTION GUIDE

INSTALLATION PROCESS

1. Take the module and attach the 16-pin patch lead connector for steering wheel control retention, then make the required connections to the aftermarket head unit..
   Different stereo brands might use different ways to connect, like a 3.5mm jack, an SWC IR wire, or two wired inputs (KEY1 and KEY2). If you’re unsure, check your stereo’s manual for details, or look for labels on the stereo cables.
2. Connect the 18-pin connector for power and steering wheel controls from the vehicle.
3. Connect the ISO to the head unit or Aerpro head unit specific harness.
4. Plug in the car-specific leads from the main interface harness to the matching connectors in your vehicle.
   Deepening on the vehicle not all connectors from the factory head unit will be used.
5. If your interface has extra leads connect them to the back of the aftermarket head unit’s specific harness.**
6. Attach the antenna adapter to the vehicle’s existing antenna port from the back of the factory head unit. ..
7. If you’re interface has reverse camera retention, connect the yellow male RCA cable from the interface to the female RCA port on the rear of the aftermarket head unit. **
8. If you’re aftermarket head unit requires a DAB antenna, plug the DAB antenna connector the head unit.
9. After connecting all cables and extra parts, make sure to test the stereo and the steering wheel controls before putting

SETTING THE DIPSWITCHES
This interface includes a set of dipswitches. Consult the dipswitch selection guide to select the appropriate configuration. To activate a dipswitch, press it downward into the ‘ON’ position. Refer to the diagram for an example of the ‘AERPRO’ dipswitch configuration.

BUTTON REMAPPING

BUTTON REMAPPING
The steering wheel buttons listed offer the flexibility of being re-configured or assigned dual functions. The availability of these buttons depends on the specific vehicle to which the interface is being installed and if the aftermarket radio supports them.
In addition to button remapping, we offer the option to assign dual functions to each button on the steering wheel. This means that every button can be programmed to execute both a short press command and a long press command.
You can also add your own bespoke configuration. Button configuration can be done by PC, MAC and smart phone via the USB port.
Button Remapping instructions can be found in a separate guide on our website (https://aerpro.com/remapper).

DIPSWITCH 5 & 6
Dipswitch 5 & 6 are reserved for vehicle specific configuration.

KEY1 and KEY2	KEY1 and KEY2 are specifically tailored for analog learning mode-style radios. Our SWC module is designed with a resistor chain that precisely matches the required resistance for seamless compatibility with this type of head unit.
KEY1 and KEY2 EXTEND	This mode extends every button press to 2 seconds during the learning process. However, with roily wheel-designed steering wheel buttons, holding for 2 seconds isn’t feasible. Our KEY1 and KEY2 extend feature addresses this by automatically prolonging each press, simplifying head unit programming even in such scenarios. Extend mode is not intended for normal use, it is only used in the teaching process.
ANALOG SINGLE WIRE and ANALOG SINGLE WIRE EXTEND	This function operates similarly to KEY1 and KEY2 but transmits all unique values through the IR SWC single wire. This is crucial for compatibility with learning-style head units featuring only one learning input wire. To ensure compatibility, we’ve incorporated this feature into our steering wheel control interface, ensuring seamless operation across various head unit setups. The Analog Extend mode functions identically to its counterpart within the KEY1 and KEY2 system but transmits through a single wire.
