Back from the trip. The unit did OK except in IL. It took me down every country farm road in the area. Apparently, the data and algorithm can't differentiate between a paved farm road and a main highway. But we did get to the desired destination.

We did the unit swap recommended by one service rep. Instructions said the new/refurbished unit would come preregistered and with latest updates. It didn't. In fact, it wouldn't turn on.

Decided to play a bit so plugged it into the computer. It came up and I started the registration and update process.

No error messages. No connect/disconnect tones. The whole process looked normal until the end. Then the unit said the files were corrupt.

Garmin instructions are poor at best. But, after trying some more I broke out the powered USB hub.

Everything looked the same as before. Except the update took.

Most of the people I know don't own anything but laptops. Apparently Garmin's poor design hasn't kept up with the world.

Now to see if the battery is good.

I'll have to think for a long time before buying a other Garmin consumer product.
