Went from a tomtom to this Navigon for the price : definitively a bargain for 50GBP (not on amazon) but really a shame that none of the POI can be updated manually. The only way to do it is to purchase a separate software, poiwarner, which finally adds to the overall cost... and doesn't make it a bargain anymore!
Everyday use needs some practice (not as good as tomtom which I'd been using for 5 years) especially since you can't really browse the different routes by roads, only by map... not very practical when you're not sure if it'll take you on a motorway or on a parallel B road...
Takes a long time to find a satellite (2-3 minutes, whereas it was instant on my old tomtom) which is really annoying too. I would have expected a much better GPS chip in a satnav which normally retails at the same price as the basic tomtom...
The safety cameras are a good option but certainly not as good as those I could easily update myself on the tomtom ( and not as complete: the navigon database only shows the fixed speed cameras whereas my tomtom used to show fixed and mobile ones, much more useful, especially when travelling in France)
You get what you pay for... Will certainly go back to Tomtom in a few months time ...
