If you ask them to, Martin and Dennis will go over the instruction styles you're likely to see before the Mini-Rally starts. Here's the event info:

Things that are good to have in the car are listed below. However, nothing but a single writing instrument is really essential:

Pencil, pen, clipboard, a watch that times to the second, calculator, and a GPS unit if you have one (indicating upcoming roads, and the compass direction that you're travelling in.)

The maplight on the STi is adequate to read by, but will put some glare on the windshield. Cover it or turn it off at stop signs when it's dark.

KWRC SNATR's are really this simplest entry point to the sport. THey usually even include a break after one hour on the road, and kids riding in the back would probably be fine.
