For owners of older Toyota 4Runner models looking to bring their in-car tech into the modern age, a head unit upgrade can make a world of difference. If you’ve been eyeing the features of the 2020 Toyota 4runner’s Entune 3.0 system, you might be surprised to learn that retrofitting it into earlier models is not only possible but also remarkably straightforward. This guide delves into a successful Entune 3.0 head unit retrofit, offering insights and details for those considering a similar upgrade for their vehicle.
One resourceful 4Runner enthusiast decided to take on this upgrade, sourcing a non-JBL navigation Entune 3.0 head unit from a salvage vehicle. Inspired by successful retrofits in Tacoma models, they explored the compatibility of the Entune 3.0 system with older 4Runners. Research indicated that Entune 3.0 head units across Toyota models share connector similarities. The crucial step was securing a compatible wiring harness to bridge the gap between the older Entune 2.0 connectors and the newer Entune 3.0 system.
To solve the connector challenge, they reached out to Auto Harness House, a specialist in custom automotive wiring solutions. The result was a custom-made, plug-and-play harness specifically designed for this retrofit. For around $190, the harness included the necessary connection for navigation functionality. A more budget-friendly option at $135 is available for those who don’t require navigation directly from the head unit.
For owners of 2012 and earlier 4Runner models, some additional components are needed due to connector differences compared to the 2014-2019 models. These include adapters for GPS, USB, and the backup camera. Specifically, for the backup camera, adapting the older connector involved splicing a 2014-2019 male connector end to the female end of the 2012 connector. A separate USB adapter is also necessary to accommodate the new connector used in Entune 3.0 head units.

Regarding XM radio, it was noted that pre-2014 4Runner models might have a different XM radio antenna. While an adapter was tested, it didn’t function with either the Entune 3.0 or 2.0 head units in this particular older model. However, this might not be an issue for 2014 and newer models as they share connector types with the Entune 3.0 system.
The installation process itself was reported to be relatively straightforward. Initial startup of the new head unit involved a GPS reset period of about 10 minutes. Bluetooth functionality also initialized within 10-15 minutes. Importantly, the backup camera integration through the custom harness worked seamlessly, and Android Auto became instantly available upon USB connection.

The upgrade to the 2020 Entune 3.0 head unit, with its appealing 8-inch screen, proved to be a significant improvement. The user highlighted that the sound quality was excellent, comparable to previous aftermarket and upgraded factory units. The modern look and enhanced features of the 2020 unit breathed new life into the older 4Runner’s interior.

It’s crucial to note that this retrofit is confirmed to work for non-JBL sound systems only. Owners of 4Runners with JBL systems may face different compatibility challenges and this specific guide may not be applicable.
In conclusion, upgrading to a 2020 Toyota 4Runner Entune 3.0 head unit is a viable and rewarding modification for owners of older models. With the right harness and adapters, a significant tech and aesthetic upgrade is within reach, bringing features like Android Auto and a larger touchscreen to older vehicles, enhancing the overall driving experience.
