The interface of this software is appalling. It is impossible to give numbers in the streets; addresses are incomplete. I did not understand how to enter the favorites. Yet these are the first things to do with a browser. So I quit the costs. I expected to find an alternative to GPS Navigation & Maps Skobbler has some flaws. Compared Gps Nav & Maps is not bad at all; we can take over immediately without asking any questions, and he led me safely, that's essential.
