2. I haven't noticed this, but I'm confident they will address the legibility issues in a future update. Seems to be the most common complaint.
I hear you and I'm hopeful too, but in this case it wasn't just the legibility. It was the actual map itself. It was just much dimmer. Mostly due to the color scheme, I think. But like I said, it hadn't bothered me before. Not until I had been using TomTom for a while and then opened up Navigon immediately after. This was also on a fairly sunny day. A/B the two, if you can.
