You've got a garmin? then it's time to practice. For you next few rides, create a gpx file (tons of sites let you do that) and load it into your garmin, then follow it. You'll work it out in few rides. Ask questions here if you can't.
I use a gpx for all my audaxes and it works fine. I like to have the route sheets handy as well, so they are clipped to my top bar bag. Before leaving each control, I check to remind myself how far to the next one, and where/what it is. I've also highlighted them on the routesheet before I laminate.
Good shout, tried it once and it didn't work so I went back to my errant ways. Wasn't doing an Audax then though, just following my nose...
