I've had it for a month now and it's working flawlessly. I have like all the info needed on single 7" screen (position, lap, speed, gear, current lap, last lap, best lap, lap diff, fuel left, fuel last lap, fuel est. laps, fuel avg/lap, tires temp/status/block, car behind, car in front, throttle and brake pedal, rev leds, lights and motor status), so pretty crowded, but it's still manageble. The only thing that doesn't work, but it's no big deal, is best lap time. It only counts current session. Must admitt tho, haven't driven for almost two weeks, but for me, it's either HUD Dash or VDash.
Edit : Oh, and gear flashes when overreving.
