Nice build and nice video man, thanks! I'm actually thinking of building something like this myself. Based on the XU4 running Android also. Would you perhaps consider elaborating a bit in this topic on what hardware and software you used to get it all up and running? The video is great, but I find myself going through these topics after a couple of days or weeks, once I'm further down in my investigations. It helps so quickly see what items were used for a particular problem.
I didn't have the time to watch the entire movie yet, something I can hopefully do tonight. So I'm sorry if this answer has already been given in the video, but by now I think I've figured out most of the parts I'll need, but so far I haven't found any info of how people use it as a carkit; eg. connecting your phone through bluetooth, dialing numbers and answering calls through the carpc and using the microphone and the speakers connected to that.
Something like this:
Is the "carkit" part something that is already build into Android, or do I need to install separate software to do that?
Also, my experience with the Chinese android units in terms of audio quality is that the other party has a hard time understanding what I'm trying to say. Something a better microphone might improve, but some sort of DSP'ing on the microphone's end might improve. Does anyone know of an app that could do that?
