The user may even be on this site. Anyway I loved this shot and thought it would be great to see how others are using their tablet. I will be posting one of my own this weekend.
I've got J1850 going over Bluetooth (and my 10Hz GPS) so I can get RPM, gear, turn signals, etc. I'll have the instrument cluster done when I have some free time. For now, I just save all the data to KMZ files to review in Google Earth.
One reason I got the N810 was the transflective screen.
(The speakers are from my DockNRock - I still need to do some wiring and shielding from vibration and 75mph insects).
