It shows the blank screen when connected to the USB, I have not tried to install it in my car as I was expecting to see something on the screen to confirm the program was loaded and everything was functioning. I am not sure which MPGuino version I am using I downloaded it in December and pasted it into Arduino software and uploaded it. (it shows it as sketch 081213a ?) it said done after about 30secs when I uploaded it - the message at the bottom of the screen says Binary sketch size 14194 bytes of 14336 byte maximum. When I reloaded it again just now I no longer get a blank screen but arrows pointing left? But it does not flick through the screens when I push the buttons as described in the installation text.
Thanks
Terry
