I've been pondering for a fair while now on getting an Android system displayed up on the Sat Nav screen and ultimately be controllable by the existing Sat Nav and steering wheel buttons. In theory it's doable. I had a PC displaying up on the screen until last year when the PC had a hard drive failure. I took the PC out to fix and just never got round to it. I achieved that by putting the VGA output from the PC into a scan converter and getting an RGB with separate synch signal (RGBS) out. This is what the Sat Nav uses as its input. Here you can see the CarPC application (MediateICE) running on the Sat Nav screen. To the right of the screen you can see a Sony stalk that I use to use as the main means of controlling the PC. I could do essentially everything from the stalk, select any button on the screen, go back, press select, next song/vid, previous song/vid etc. This software gave me Music, Video, Weather and Navigation using PC Navigator. I also made a plugin for Windows Mobile, basically back in the days when I had a Windows Mobile phone I was able to display that on the screen too. This was great as it meant I could get Tomtom software running on the phone an displaying on the screen. Anyways by the time the hard drive failed in the PC I had got board of this setup which was now like 5 years old. So this caused a lack of motivation which meant I never actually got round to fixing the dead hard drive. What did intend to do though is plan on having an Android system running on the screen instead. This would be more challenging as I would need to be more inventive in how I implemented controlling the Android device. Anyways it wasn't until this week when Rob (aka Rhardley) in this http://h-tune.co.uk/club/threads/4473/ mentioned that he wanted to display Android track info on the LCD screen that I got off my back side and started looking into my Android project. So I came back from work the other day and got stuck into. First aim as proof of concept was to get my Samsung Galaxy S3 displayed on the screen. I'd already previously ordered the bits that I needed to do this. I had a Galaxy S3 MHL Micro USB 11pin to HDTV HDMI Adapter and a HDMI to VGA converter. So the theory was that I should able to go from Galaxy S3 into HDMI adaptor into VGA adaptor into the existing scan converter (to give RGBS) I plugged it all in and hey presto Android on Honda Sat Nav screen So now that I know that I can display the screen I can start thinking about control.
