I have used this map in Baja and to me its a must! To be able to see the available "roads" that are near the race course is very cool and may help you figure out some creative pit strategies or assist you in getting parts to a down race vehicle!
I have yet to use this card. But if it is like any of the other PCI software there will be nothing but a two thumbs up. I will commit again after we spend time at the 1000.
