Features & Benefits

Complete Vehicle-Specific Upgrade Kit for Ford Everest 2015-2022 and Ranger 2015-2021: The AX9129CT includes all components required for a complete installation across the Ford Everest (2015-2022) and Ranger (2015-2021) without additional accessory sourcing. The vehicle-specific installation kit covers the fascia, Infodaptor interface, vehicle-specific harness, USB/AUX/HDMI input panel mount, antenna adaptor, and patch lead requirements of these Ford platforms.

Infodaptor Interface Included: The vehicle-specific installation kit includes an Infodaptor interface module that provides the integration between the new head unit and the vehicle's factory electronics architecture in the Everest and Ranger platforms. The Infodaptor allows the aftermarket head unit to communicate correctly with the vehicle's factory wiring and control systems, enabling vehicle feature retention as part of a complete installation.

Vehicle-Specific Harness Included: The vehicle-specific harness is matched to the factory wiring connector layout of the Everest and Ranger, providing a plug-and-play wiring interface between the factory vehicle loom and the new head unit without requiring cutting or splicing of the factory wiring.

USB/AUX/HDMI Input Panel Mount Included: The vehicle-specific installation kit includes a USB/AUX/HDMI input panel mount that provides accessible connection points within the vehicle's interior, retaining or providing USB, AUX, and HDMI input functionality at the dash panel level after the new head unit is installed.

Antenna Adaptor Included: The vehicle-specific installation kit includes an antenna adaptor to ensure the factory antenna connection from the Everest and Ranger interfaces correctly with the head unit's antenna input, maintaining full AM and FM signal performance after installation.

Black Fascia Kit for Everest and Ranger Dashboard Integration: The included black fascia kit is designed specifically for the Ford Everest (2015-2022) and Ranger (2015-2021) dashboard profile, providing a clean, factory-fit finish around the 6.8" head unit that integrates with the interior trim of these Ford models.

6.8" Capacitive Touchscreen at 1024x600: The 6.8" capacitive touchscreen delivers a large, responsive display with 1024x600 resolution for clear navigation of maps, media, and settings, well suited to the dashboard opening of the Everest and Ranger.

Wireless and Wired Apple CarPlay and Android Auto: Both Apple CarPlay and Android Auto operate wirelessly for hands-free smartphone integration, or via wired USB connection for simultaneous charging. On first wireless connection, a one-time pairing via Bluetooth and Wi-Fi is required before subsequent connections become automatic.

Bluetooth V5 with HFP 1.6 HD Voice: Bluetooth V5 supports A2DP high-quality audio streaming, AVRCP media control, PBAP phonebook access, and HFP 1.6 HD Voice quality hands-free calling. Both an internal microphone and an external microphone with mount are included, allowing the external microphone to be positioned optimally in the cabin.

13-Band Graphic EQ with Time Alignment: The 13-band EQ covers 32Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 10kHz, 12kHz, 14kHz, and 16kHz for precise acoustic tuning, complemented by time alignment and a subwoofer low-pass filter for a complete onboard tuning toolkit.

4V 6-Channel RCA Preouts: Six RCA preamp channels at 4V covering front, rear, and subwoofer outputs allow external amplifiers to be added to the system with a high-output, low-noise signal. Subwoofer level control is also provided directly from the head unit.

720P AHD Surface Mount Camera Included: The included 720P AHD surface mount camera uses a Sony 225 1/3" CMOS sensor, a 150-degree lens angle, optional parking guidelines, and an IP67 waterproof rating. It can be mounted as a front, rear, or reverse camera and connects to the head unit via the included 6-metre RCA cable with in-line reverse trigger wire.

Dual AHD 720P Camera Inputs: Two independent AHD 720P-compatible camera inputs allow the included surface mount camera and a second camera to be connected simultaneously, supporting configurations such as front and reverse or reverse and towing cameras.

6-Colour Button Illumination: The key illumination is selectable across six colours including red, yellow, green, blue, purple, and white, allowing the button lighting to be matched to the Everest and Ranger interior.

AM/FM Tuner with RDS: FM tuning covers 87.5-108.0MHz with 18 presets, and AM covers 522-1710kHz with 12 presets, with RDS support for station and track information display.

Frequently Asked Questions

What is the Infodaptor interface included in the AX9129CT?

The Infodaptor is a vehicle-specific interface module included in the AX9129CT installation kit that provides integration between the aftermarket head unit and the factory electronics architecture of the Ford Everest and Ranger. It works in conjunction with the vehicle-specific harness to allow the head unit to interface correctly with the vehicle's factory wiring and control systems, enabling vehicle feature retention as part of a complete installation.

What does the USB/AUX/HDMI input panel mount provide?

The USB/AUX/HDMI input panel mount is a vehicle-specific accessory included in the installation kit that provides accessible USB, AUX, and HDMI connection points within the Ford Everest and Ranger dashboard area after the new head unit is installed. This retains or provides convenient input access points at the dash panel level without requiring the occupant to reach behind the head unit directly for device connections.

Does the AX9129CT retain the factory Ford Everest and Ranger steering wheel controls?

Yes. The vehicle-specific installation kit includes a universal SWC patch lead that connects to the head unit's SWC input, allowing the factory steering wheel audio controls to operate with the new head unit after installation and calibration. The Infodaptor interface and vehicle-specific harness support the integration of steering wheel control functions across these platforms.

How does the AX9129CT differ from the AX9129K for the Ford Everest and Ranger?

Both the AX9129CT and AX9129K are complete head unit upgrade kits for overlapping Ford Everest and Ranger date ranges, sharing the same head unit specification and 720P AHD surface mount camera. The AX9129CT includes a significantly more complex installation kit with an Infodaptor interface, vehicle-specific harness, and USB/AUX/HDMI input panel mount suited to the later Everest and Ranger models with more integrated factory infotainment architecture. Use the Aerpro What Fits Your Car Guide at aerpro.com to confirm which kit is correct for your specific vehicle and build date before purchase.

Can external amplifiers be connected to the AX9129CT?

Yes. The head unit provides 4V 6-channel RCA preouts covering front, rear, and subwoofer channels, allowing external amplifiers to be connected for higher output power or a dedicated subwoofer channel. The 4V output voltage provides a strong, low-noise signal compatible with most aftermarket car audio amplifiers. Subwoofer level control is also available directly from the head unit for convenient bass adjustment without accessing the amplifier directly.
