Hi Jon, Welcome - I did this http://www.z4-forum.com/forum/viewtopic.php?f=29&t=56746 - so yes, you can easily emulate all of the original functionality of the screen with an Arduino.
and........ favourited! This would have been well useful when i dismantled the screen housing
The android pc is going to be a 6" Phone/tablet (Phablet.. I dislike that word) Which will have a sim card in it it will have my music on it gps and so on. I have also ordered the OBD USB-OTG cable so I can modify comfort options get diagnostic read outs and view running data and sensor read outs I have a few other plans for it but will see if they work first
Dan I am off to work and will read your thread when I am there but I am imagining I am going to have a problem powering the phone and using USB-OTG at the same time will work it out but not sure if i'll need a manual switch in the cabin to switch between data read out and charging and it looks at first glance like the inbuilt ignition based motor might not work but will read properly at lunch.
Cheers
Jon
