I have a TOM TOM One. I recently drove from New England to Florida. I got around the "via issue" of only making one change by cutting the trip into segments. But is there a way of changing the Route TT chooses by putting via a Route number instead of choosing a location along the route? I wanted to take Route 301 around Balt/DC but it was difficult because TT kept trying to connect me back to ( 95 at different points along 301.
