Macro 27

Mac27 routing to the area of your destination, then use the customer code to look up the Mac19 routing into your destination.

 

The fuel route, macro 27 is the shortest distance. Macro 15 gives you the shortest time. ALWAYS check the routing against the RMCA! I use mapquest and Google Earth as well to double-check the macro 19 instructions, and of late have been using the maps app on my Android smart phone as well. Looking at the satellite view of the area helps you put the local instructions into context, as well as see potential problems before they become disasters.

Don't ever just blindly follow GPS turn-by-turn instructions either, without bouncing them against all of the above. Those databases are only as good as the programmer that entered the data.

If you find the macro 19 instructions to be incorrect, or are the first lucky driver to go somewhere- YOU can fix things! Put your changes into macro 28!!

 

Yeah it does some lame things sometimes. Run over to the mountains for fuel instead of going across the plains, take the northern interstate and then drop down through 200 miles of goat trail instead of taking the southern route with only 50 miles of goat trail (in the winter), get 146 gallons and run over 1400 miles to the next fuel stop, from Laredo TX run I-35 south for 100+ miles.

It seems to work better if you are heading on the route you want to take as opposed to parked and pointing in the wrong direction.

 

its still your responsibility to look at the paper atlas for restricted routes
