Very good product that matches the descriptions of the notices and presentations on specialized sites and builder. Excellent value for money. I use this GPS alternately in two vehicles. On one, no major problems (see below for some small flaws), on the other vehicle equipped with a thermal windshield very powerful, I have a big concern (see end). All functions are dynamic and very pleasant. The 5-inch screen is superb, very well contrasted in virtually all circumstances. The touch is very pleasant. The suction mount highly efficient, easy to implement, and holds very well. The route planning is very simple, and the re-routing is very fast, on the order of 2 to 3 seconds. The alert visually and audibly overspeed is very useful (though sometimes false reports are generated). The Live services are generally effective. Searching for information via Google is very useful when moving into unfamiliar places.
Some small flaws: The livery mapping, and even free upgrade "art" downloaded after purchase and the first connection is not completely up to date. The synthesized voice Text To Speech is too metallic, not important enough. The indication of instantaneous velocity is sometimes erratic or whimsical (causing false alarms overspeed). I found some errors on the HD Traffic reports of plugs and circulation disorders.
By cons, much more serious, the GPS receiver does not pierce the athermal windscreen seriousness and location of losses are common and very troublesome. The only solution I found is to place the GPS high on the windshield, near the rearview mirror and as close as possible to the non-thermal portion of the windshield, but the positioning is not ideal. I was advised to use a re-radiating antenna RA-60, but it costs 85 euros, or more than a third of the price of GPS !!!
