Great report Craig, I know that route well so I was able to understand what you were describing. Actually I would have got off IH 10 in Columbus because it has one of my favorite courthouses. Correctly setup, would it have stuck with 10?
Will this device learn updated information? It's a toy (sorry, TOOL) I'd love to have but I worry that it will age badly. Speaking of "love to have", can it be pulled off that stalk to make it less accessable to smash and grab types?
