A very good product. The interface is intuitive, easy to read the screen. The route calculation (and recalculation if changes "live") are fast. Contrary to what I read on some sites, captures the GPS signal without additional antenna and it very well, everywhere. Good sound quality. The doc does not specify for displaying radar, I can find the info on specialized forums ... so go to options and click on the [i] information for the option s Active since banned in some countries. The battery has a good battery life (but useless for cars with a cigarette lighter). The map set is updated and well supplied, the latest radar, practical and tourist information. Many editable parameters, additions of custom points, blocked roads etc ... SD card so easily bidouillable for connoisseurs. Brief excellent all view!
