The mountable gadget I'd like to see

[Tom_imp]

Reading through the phone mounting thread made me think of what I'd actually like to see on a built-in display along with the usual stuff like speed, tach, time, and mileage. I'd like a compass/barometer/altimeter enabled display or device. I'd like it in the car/truck too. Those items would be very useful. I do have a cheap compass mounted for navigation. I can't imagine looking down at a phone constantly. I've seen that cause a crash. I hope none of your are mounting anything on the tank.
