We had an occasion to be attending a wedding at Pensacola Beach and directions from Nuvi was to drive out of the lot behind our B&B, turn Right for 6 blocks, Left for 4 blocks, another Left for 6 blocks, then Left again 3 1/2 blocks & turn Left onto a causeway.
In fact, GPS Nuvi had us making a rather large rectangle to take the very next Left our of our B&B parking area (1/2 block from our starting point!).
I became almost violent when hubby attempted to repeat the directions later the same day!
We are still married but..........
We have a Garmin Nuvi. The darn thing seems to have a random route generator. It will generate a different route to the same location each time you fire it up.
For instance, there is a nice, simple, fast way to get from I75 in Georgia to Tallahassee, FL (and we do this a lot) - the Georgia Florida Pkwy - GA 300. But she (our Nuvi is named “Jill” after the voice she uses) will go any route BUT GA 300. These roads are typically over two lane 55 mph roads. The traffic is light, but what there is does not want to go 55mph. It either goes much faster or much slower.
I find this sort of thing entertaining when I am by myself or with just my wife and we have no schedule putting demands on us. I am never lost if my wife is with me because I am exactly where I want to be. But with kids, and/or if you are planning to go to work and school the next day..
Mostly I find GPS to be useful for “terminal phase” of a trip. You get close to where you are going, then use her for the final directions.
But I think I am going to print the directions to and from Tallahassee, laminate them, and stash them in the car.
