Nice job. i was also thinking of doing something similar.. i even started but then got bored with writing code

An idea for you, you can get arduinos to talk to android devices, plus there are now android based double din car stereos... you see where im gong?

Fast and the furious type computer display with whaterever type of input and graphical display your heart could dream of. Plus then you could run ozie explorer off the double din stereo too as its android.
