Oh, my TomTom works but it's nearly useless for two reasons:
2) The map view does not show enough detail in rural areas when zoomed out. Roads don't show up, road names don't show up. Yes, they are there if you zoom in but they disappear again when you zoom out to see what those roads connect to. Actually, this is a big problem in urban areas also.
True... the only thing really detailed is lane guidance. A Garmin that I could also load my Topo maps into would be perfect.... well... I do that anyway but it would be nice to be in the dash instead.
