Upgrading the entertainment system
There were some things I wanted to be able to do on my GH that the factory entertainment system would not do. One of those things was running an app that played music and read text to me. I bought this product on Amazon called Vovoyager 4in1 AI box. It plugs into your usb-c data port in the front dash. All I had to do was plug it in and it worked. After starting and then rebooting one time (to adjust the screen resolution, which it did automatically) it worked perfect. I added wifi (I set up a mobile hotspot on my phone) and started downloading apps. It came with Netflix, YouTube and I downloaded Prime, YouTubeTV (which I subscribe to) and other apps. Disclaimer: in many states it is illegal to have video playing on the dash screen while driving. Use caution. This thing works like a charm! It basically turns your infotainment system into an Android tablet. You can also plug a thumb drive into it and play whatever you've put on the drive (your own mp3 mix) or even a portable ss hard drive with audio or video. This opens up your system to be what it should have been. If your want to go back to your Toyota screen it's easy enough, just unplug it or tap on a special spot on the screen and it will take you back. You have everything you need here though, maps, music, everything. All for less than $70.
