We got to see a rare treat on the video taken from inside T4 truck 528. For a brief second they showed the ERTF Rallye Raid GPS Screen. The screen has quite a bit of info. I have attached a screen cap and a quick breakdown of the information shown. There is a lot of "masked" data since the course book should be what guides the competitor, but it will "activate" when within a predetermined distance. This is how Robby knew they missed a waypoint on stage 3 and had to go backwards on course to pick it up. The data is stored in the GPS and then downloaded and checked at the end of the stage. For further reading I have attached the manual to the GPS unit. Good stuff.
