Would have been nice to see some mapping visual options improved (better / clearer zooming rather than the smudged mapping lines they currently offer, not just a new (updated) interface
However, Navigon do make some nice units, have some innovative features, and usually well priced - be interesting to see what Garmin now do to them...
