dunno... I'm basically waiting for the announced trial of it.
Most people I know that have had navigation units for the cars and most of the german online community claim that navigon builds the better units and software for quite a while ago, while TomTom WAS better years ago, so I tend to believe that.
All tests reviews today claim that its works very good, half the people are even surprised about its performance, claiming it outperforms their didicated devices by accuracy, GPS fix time (greetings from a-gps) and especially the programs speed. The iPhone is definitely no slouch performance-wise, and even 2G and 3G iPhone easily outperforms dedicated devices when calculating alternate routes using this software. This has been confirmed by people I personally know this afternoon, so my hopes are high
I'm highly likely to buy this app during next week when I have read more tests/thoughts.
