The overall impression is good. The unit makes a solid impression. The operation is self-explanatory. The price / performance ratio based on device maps / updates and live mode is acceptable. In other providers have to pay to each option.
As I come to the Navigon world from another world, I am quite disappointed with the Card details but. The maps of TomTom are quite spartan. The 3D representation very computerized and not detailed. Preliminary information on points of interest such as gas stations and parking lots of the same are not visible in the map, but only in a navigation mode in the system tray. But it has not always the navigation mode, and does not need him always.
That could Navigon (live) better and here is at TomTom certainly room for improvement!
Let's see what TomTom there still delivers, for the Go 600 we have a lifetime to expect updates.
