Gutted by "BLAUPUNKT"

Since I am professionally Telekom ST as a suppressor on the road, about 250km runterradle day, I am dependent on NAVI's, every manufacturer I've already had, cheap, expensive, manufacturers, whose names could not even write, each has its advantages, its drawbacks but in the whole they were doing their work, used to operate at everyone, but what can one expect from a high-tech device from the Far East for about 100.- for already. I thought me, taking something "better, more expensive, where a household name draufsteht- BLAUPUNKT costs, even far more than the other. In Amazon purchases, came as usual immediately! Unpacked, looks so very high, turned on, the first major Disappointment: display resolution that each one cheap mobile phone has a beautiful picture, jerky, scandalizes all sides, the route guidance is a mess, routes are calculated to shake the head, for example, if I see a road exit, it does not say: Please repent, but it will calculate a new route with more than 20km! I come through villages by (UNWARRANTED !!!) that no one knows, and above all it should not have been. Well, maybe there is an update, plugged in to the PC, a 2-hour procedure durchbemacht the PC recognizes it, (Am I really in a good mood, how is that a layperson do ???) Update of over 4 hours downloaded, installed, Switched, Hung! no longer works !! Around the Blaupunkt page no service available! Back to Amazon- Easy (thanks to Amazon). Well, what I thought, Monday device, try it again, saw indeed from high quality, come new device, again gone through exactly the same, to update no function and no service available !! Back to Amazon, I'm sorry, but it's too expensive! I find it just a pity his name sells Blaupunkt so cheap, sold such inferior equipment, it seems white, so they have all the NAVI service on the website or hidden away! My favorite is probably then again TOMTOM ...... Too bad, I was always so proud of Blaupunkt .....
