What you should have done was invest in a GPS navigation device.

Though it is not recommended you mount a large until on a motor cycle or riding lawnmower.
GPS navigation works using a series of satellites (generally 24-32) that are in orbit around our planet. The satellites radiate a constant signal, much like your spouse does when you miss a turn.

This is not just on the highway either, you could be anywhere where there's sky and your GPS will work.

These generally offer a lot of mapping programs you won't get with the standard handheld unit- In other words, more bells and whistles.
Accuracy is the main attraction to a GPS lifestyle. (And yes, it IS a lifestyle babe) Updating your GPS navigation system is very important.

Where to put your GPS shouldn't be a problem either. They generally come with a window mount bracket that is specially made for the unit its self. That's might nice of them to do so. Just make sure that you don't mount it somewhere that will obstruct your vision. Your trip will be a lot shorter if you take out a drive-thru window before you even get out of the state.

You will not only find the shortest route from point A to B, but you will be able to do so with the confidence of someone who knows where they are going.
