Your GPS tells you to turn left and turn right but can you really trust that seemingly smart, polite woman, talking to you from that little box strapped to your dashboard?

I don’t know about you, but GPS Sally is constantly getting me lost and she keeps recalculating… recalculating… recalculating

I’m reminded of a news program on TV about three women who used their GPS while visiting Death Valley National Park. It was a day trip so they only packed a few bottles of water with them and very little food. They had no paper maps of the area and nobody knew that they were going to visit the park.

Following the directions of their GPS, they were guided to an unused part of the park, well off of the main road and as they continued driving and circling around and around, day became night and they ran out of gas.

There was no cell phone signal. The next day the temperature rose to a whopping 100°F.

As I was watching the program it brought back my own memories of a drive through Death Valley National Park when we mis-timed sundown (not too calculated for this traveller right?). Let me tell you, it was pitch black on the road with no street lights and then a sand storm started. We were so scared but at least we had headlights, gas, we knew where we were and where we were going….

But back to our original story…

They managed to miraculously survive out in the desert by finding water and shelter in an unused trailer before finally being rescued 3 days later.

There are lots of GPS horror stories out there…just do a Google search and you’ll see pages and pages of them.

Don’t trust your GPS blindly.

I like to know where I’m going before leaving the house.

I can’t stress this enough but you should always make sure that your GPS, be it a portable unit or one built directly into your car, has the most up-to-date maps loaded into the software.

Navigation.com is a handy site where you can find all recent map updates for all car manufacturers in one location.

If I’m going on a road trip or driving somewhere unfamiliar near home, I prefer to plot out my route ahead of time, using AAA / CAA triptiks and/or maps.

With highlighter in hand I mark the most direct route and use my GPS while driving to confirm that I’m on the right track.

If you don’t belong to an auto club, you can also print out maps and directions from various websites such as Google Maps or Yahoo Maps. I get a map of the entire region, then local area maps with turn by turn directions.

A good idea is to also have a compass in your car.

Isn’t there an app for that?

There all kinds of map and navigational apps available for your cell phone. I think they are great for when you are in a major city and have a vague idea of the area. But if you are on a road trip, in my opinion, you are using 1 form of technology as a backup for another form of technology. What if they are both wrong? What if they conflict? Which is right? What if you don’t have satellite signal, or run out of power….

Sometimes, it’s best to rock it old-school with plain old pen and paper.
