I do have Map&Guide8 / Travelbook 3.5.
Itīs just perfect. It even has speech-nagvigation. With several plug-ins you can even see the fixed radar-traps or gas stations or McDonals/Burgerking on your map. The buttons are big enough for touchscreen-usage.
I think itīs the best that we can get for europe.
But the price is, because of the great amount of features, very high...
If you really want a good navigation software in your car you should get Travelbook. I think the only problem is your screen, cause even my 6,4" screen is pretty small for this software.
Hope I could help
