Upgrading your car’s head unit can dramatically transform your driving experience, and the ATOTO A6 Pro is a popular choice for those seeking a smartphone-like interface in their vehicle. But did you know you can unlock even more potential by pairing it with a Bluetooth OBD2 tool like the AC-4450? This review delves into the benefits of combining these two devices, enhancing your car’s functionality and providing real-time diagnostics right on your dashboard.
The ATOTO A6 Pro, after a couple of months of use, proves to be a responsive and feature-rich car radio. Its crystal-clear touchscreen, boasting a 1024×600 resolution, remains vibrant even under direct sunlight, outperforming many standard car stereo displays. The sound quality is exceptional, delivering clear audio through JL Audio component speakers without any noticeable distortion, even at high volumes, in a setup without an external amplifier. The built-in 13-band equalizer offers presets and customizable settings, though custom preset saving is not available. Overall, the ATOTO A6 Pro operates smoothly, fulfilling its promises with consistent performance and regular firmware updates from ATOTO. It includes external GPS and WiFi antennas, supports factory Toyota reverse cameras and ATOTO dash cams, and integrates with steering wheel controls.
To fully utilize online features like Google Maps and app downloads, a WiFi hotspot from your smartphone is essential. Data consumption should be considered, especially for frequent app usage and navigation. The ATOTO A6 series offers various models, with the A6 Pro standing out for its superior screen and amplifier. While newer models feature capacitive buttons, some users have noted parallax issues. The physical buttons on the A6 Pro offer a classic feel and avoid this potential screen distortion.
The true power of the ATOTO A6 Pro extends beyond entertainment. With full access to the Google Play Store, you can install a wide range of apps, including the Torque app. This is where a Bluetooth OBD2 tool, such as the AC-4450, becomes invaluable. By connecting an AC-4450 or similar OBD2 dongle, you gain access to live vehicle data directly on your ATOTO screen. Monitor RPM, coolant and intake temperatures, O2 sensor readings, estimated MPG, and diagnose fault codes in real-time.
Voice activation is supported through Google Assistant, Alexa, and other apps, enhancing hands-free control, though response times may vary compared to dedicated smartphone assistants. While picture-in-picture might not be directly supported for simultaneous map and media control, steering wheel controls ensure easy adjustments without disrupting navigation.
For communication, the Android 6.0 Marshmallow OS supports call syncing and contact favorites. Third-party apps can further enhance functionality, but hands-free texting directly through the unit might require workarounds. “Headunit Reloaded” can enable Android Auto/Apple CarPlay, but performance may vary.
The ATOTO A6 Pro acts as a versatile Android device in your car. Install podcast apps, streaming services, and customize it to your needs. However, maximizing its diagnostic capabilities requires integrating an OBD2 Bluetooth dongle like the AC-4450.
Expanding Functionality with the Ac-4450 Bluetooth Obd2 Tool
Beyond the standard features, consider these additions to maximize your ATOTO A6 Pro experience:
- Bluetooth OBD2 Dongle (like AC-4450): Unlocks the Torque app for live vehicle diagnostics and performance monitoring.
- ATOTO Dash Camera: Records driving footage directly viewable on the radio, offering immediate evidence in case of accidents. The ATOTO 44P2 dashcam provides 1080P resolution and plug-and-play USB connectivity.
Installation and Wiring Essentials
While physical installation is generally straightforward with color-coded wiring, some aspects require attention, especially for steering wheel controls and rearview cameras.
Steering Wheel Controls:
Using the Metra 70-8814 harness simplifies wiring. Connect the ATOTO steering wheel control wires to the Toyota harness as follows, noting the crucial resistors:
- ATOTO Steering Wheel Control #+ to Toyota PURPLE AND WHITE (middle wire) with a 300-ohm resistor in series.
- ATOTO BLACK GROUND to Toyota White/Red stripe.
- ATOTO Steering Wheel Key + to Toyota Yellow/Black line with a 2000-ohm resistor in series.
Important Resistor Note: Resistors are essential for Toyota vehicles due to lower button resistances incompatible with the ATOTO. 300-ohm and 2000-ohm resistors are recommended, but values within the 200-10000 ohm range can work. Consult ATOTO support for vehicle-specific recommendations.
Rearview Camera Wiring:
Refer to online guides like the provided YouTube video for visual assistance. For factory rearview cameras, several wiring methods exist.
-
Retain Factory Mirror Display: Tap into the factory camera positive and negative wires and connect an RCA cable to the ATOTO backup camera input, maintaining the factory mirror display.
-
Disable Factory Mirror Display (Enhanced Clarity): For potentially improved picture quality on the ATOTO, disable the rearview mirror display. Use a PAC-39 to provide 6V power to the camera. Connect the camera wires to the ATOTO backup input. Run a wire alongside the RCA cable for reverse signal input to the ATOTO.
USB Connection:
Replace the factory AUX input with the flush mount USB connection for a cleaner look and enhanced connectivity. Connect this to the ATOTO’s “EZ-connect” USB port for data transfer and mirroring. A separate 2A quick charge USB port is also available.
Customer Support:
ATOTO customer support is generally responsive, though based in China, which may lead to slight communication delays and potential language nuances. Be prepared to clearly articulate your issues for efficient support.
Conclusion:
The ATOTO A6 Pro is a powerful and versatile car radio, significantly enhanced by integrating a Bluetooth OBD2 tool like the AC-4450. This combination provides not only entertainment and smartphone-like features but also valuable real-time vehicle diagnostics, empowering you with data and control over your car’s performance and health. Whether you’re a car enthusiast or simply seeking a smarter driving experience, the ATOTO A6 Pro and AC-4450 pairing offers a compelling upgrade.
