Summary: OK, it works well. But- they stopped updating the maps in 2008 (as near as I can tell) and it doesn't work intuitively. ViaMichelin does have a good website, though. The TomTom will get to a map in maybe two clicks, the ViaMichelin is more like six. It does have a wide screen, a built-in stylus, a really sturdy mount, high quality charger, etc. It doesn't support text-to-speech so it's "Turn left" not "Turn left on Main Street".
Summary: As for what I do not like about this product: This product has a user interface that takes some getting use to. More so than a Magellan, Garmin, or TomTom brands that I have used. The unit does not allow for misspelling of streets or locations and cannot run a search for names that are similar. At times, it can take to long to search the information stored on the memory chip.
Summary: I've had a TomTom before and this unit, for the money, is as good. The navigation in the menus are a little different but like any it takes a few times and then you remember the sequence to do different things. What I did not like was the AC and DC plug. It is identical to the Motorala plug and so I thought I could use my cell phone to charge car and wall charge to charge the GPS while on the road and trip.
