The Nexus 7, a powerful yet compact tablet, offers a unique opportunity to enhance your in-car experience when paired with an OBD2 scanner and Android Auto functionality. This setup unlocks a world of possibilities, from advanced diagnostics to navigation and entertainment, all powered by your trusty Nexus 7.
While Android 5.0 (Lollipop) and later natively support USB Audio, earlier versions might require custom ROMs or kernels. This process can be complex and may void your warranty, so proceed with caution if you lack experience. Alternative audio solutions are recommended for less tech-savvy users.
The true power of this setup lies in utilizing car-specific applications. Torque, for example, connects to a Bluetooth OBD2 scanner (available for around $15) plugged into your car’s OBD2 port, typically located under the driver’s side dash. This provides real-time engine diagnostics, fuel economy data, and even GPS tracking.
Beyond diagnostics, your Nexus 7 transforms into a robust navigation system. Apps like Google Maps and Navigation leverage the tablet’s GPS hardware, enhanced by a WiFi connection. While some tablets boast 3G or 4G connectivity, WiFi tethering from your smartphone offers a reliable alternative for high-quality GPS, music streaming, voice search, and notifications.
For those familiar with rooting and custom ROMs, WiFi tethering is likely a familiar concept. Utilizing your phone’s data connection provides a stable internet connection for the Nexus 7, ensuring seamless functionality for various apps. A mobile hotspot serves as another viable option if your data plan allows.
Streamlining the setup process further, NFC tags offer a convenient solution. These programmable tags automate tasks with a simple tap. Imagine tapping a tag on your car’s dashboard to activate your phone’s WiFi hotspot, then tapping another tag on the Nexus 7 mount to launch GPS, Bluetooth, and a car docking app like AutoMate. This eliminates the hassle of manually configuring settings before each drive.
In conclusion, combining an Android Auto compatible head unit, an OBD2 scanner, and a Nexus 7 unlocks a plethora of features for your car. From real-time diagnostics and navigation to entertainment and streamlined automation, this setup empowers you to transform your driving experience. By leveraging the flexibility of Android and the power of the Nexus 7, you can create a personalized and connected in-car environment tailored to your specific needs.
