My father in law got one late last year.
He lives in Galveston, about a 4 hour drive to Austin. He used his GPS unit to guide him to our house. It took him almost 6 hours. It had him going all kinds of out of the way.
I don't remember which one he has, but before I buy one I'll make sure it's not the same one he has.
