I'm on the west side of jacksonville florida and I also have a tom-tom. You need to go to look up new point of interest, hit the next arrow and you will see latitude and longitude. From there enter in the cordinance and hit done. It will give you driving directions to your location, when you get close go to recalculate rout, on the right side of the screen you can see the cordinance, touch the screen on them and it will ask you to configure them, change it to minutes or what ever the cache is measured in than it will show you the numbers your after as you walk around. If you need more help I'll be more than glad to help you.
