This Navi I am very satisfied. Have previously a Blaupunkt Navi had, whose service was not quite as easy and intuitive. The survey was not as good as Garmin. The Garmin Navi offers an intuitive operation, there are many useful settings available, (certainly the Blaupunkt, but somewhat more complicated), the volume is ever clearer and louder than the Blaupunkt, the graphics are a bit clearer and the brightness can also be Set slightly finer. The Blaupunkt Navi may also be a very good navigation, but personally I'm better with the Garmin cope. It is also slightly more expensive. Even in the apartment I had to turn on the Garmin Navis already after 15 seconds 6 satellite, which Blaupunkt has sought since longer and only densely found the satellite at the window. Those looking for a cheap and good Navi, is certainly well served with the Garmin. I would buy me immediately. Half a star less because the software update does not work, although I. Garmin E-Mailadr bin. After 1/2 update comes: Error during update. Have the cause is not found.
