Would be nice if it was reliable

Positives:
-The Unit is nice, thoughtful and pleasant to use.
-It Makes me go through small roads that other devices have refused to offer me.
-the information system plugs is a real plus. It allows me to choose my morning commute according to the place where are the caps. This is my only reason to turn on this device regularly, with the speed camera warnings (I have a built-in GPS in my car)

The Bad:
-The updates are slow catastrophe, despite my very fast internet connection (effective rate of 3 MW).
-an update me planted the GPS, I had to call the support
-re-upd after 3 months: the computer does not recognize the gps or can not load the driver
-the support site is VERY confused, find where we can ask the question is already an achievement.
It is sometimes a French redirected to another page in English ...
-trajets sometimes stupid: eg he tells me 20 minutes to get there, at the crossroads I take a path other than that specified, it recalculates ... and he tells me I have left only 17 minutes! That means he offered me a suboptimal way out.

Conclusion: Compared to a Garmin I possess for the bike and riding it Tomtom is more modern and simpler (as long as we do not connect it to a PC), but the updated system is really unreliable and made him lose 2 stars.
