Some of you may know that i’ve been working on a little something for the Toyota Touch (& Go) head unit. I’ve now successfully managed to get it all working and set up perfectly to my liking. After many hours of fiddling and tweaking with wires I’ve got it working. Spent hours fiddling, went through 3 methods and 4 pcs! Blew a couple of fuses, and broke my reverse camera cable in the process, but now have a fully integrated Telemetry data input into the head unit. This makes use of a hidden input on the Toyota touch which isn't enabled by default. The ‘VTR’ Input, which is basically a video composite RCA input. So this is what i’ve done and now have running…. Integrated 3 RCA panel inputs into my glove box along with a 12v ignition power supply…. A Mini Android PC in the glove box to input into the head unit. This Android pc will be replaced with a far smaller one which I am still waiting to arrive. I’ve used this one for testing as it is available in the UK. The one that’s coming from China is smaller, lighter and much cheaper. But takes several weeks to get here it would seem. I’d already tried another one from China but because of the android version it would not run Bluetooth or communicate with the car. I’ve got a little more tweaking to do with the Android box to make it more streamline but the PC now boots up, and opens up the Torque App into a dashboard automatically. Giving full engine telemetry on the screen. Including Oil Temp and Boost Pressure (If FI) along with any other data that is available from the GT86 ECU. And there is a lot! The data can be in the form of dials, graphs or numbers. Many of you know the Android Torque Pro app so anything you can do that, can pretty much be outputted to the head unit now. http://www.youtube.com/watch?v=xzwS9bIv97A Sorry for the poor video, this was done using my iPhone wedged in the passenger head rest late at night. But gives a general idea. And because it is technically just an android PC anything else you can do on android can also be done on the head unit. Angry Birds, Browser, films, music, pictures etc. This is still early development and I plan to keep on working on it to make it as possible and integrated as possible. The limitation at the moment are…. Only form of input is via Keyboard or Mouse. Slow boot-up time, I am promising settings and removing unwanted start up services to speed up boot. Only audio input is via the Front Jack Input or red and white RCA input. Audio can be played using the android pc, or inputted into the front jack from iPhone or iPod etc. But when in the ‘VTR’ Source you can’t use Bluetooth or iPod connection. And you can’t have the telemetry showing whilst listening to the radio etc. But I am working on a method so that apple users will hopefully be able to ‘air play’ to the android pc via WiFi or Bluetooth. I have this half working. Small text is difficult to read due to the 480p resolution. But setting all text to large is fine, and once in the torque app it’s not a problem. The install process is very fiddly and complicated. But I will hopefully be making some wiring looms which allow an effective ‘plug and play’ solution. I will also be putting together an install guide for those who want to attempt it themselves. I need to tidy my install up, get some decent pictures and then i’ll get together a guide. Currently the software requires a bit of tweaking and setting up to work smoothly. But again i’ll add this all into the guide.
