There is an unknown Nav company called Desnav here is their website [Only registered and activated users can see links. ].
They succeeded as marketing compared to Sygic and NNG, they have their own software which isn't good as Sygic or igo but they cover almost all operating systems Android (they have their app on play store) for wince 4.2, 5.0 and 6.0 as well.

What I like about these guys is that they did what NNG and Sygic can't do as follow:

1-Updated maps Naviteq 2016 Q3 or Q4.
2-Run their software on any aftermarket Chinese devices (If you contacted Sygic or NNG they will ask you to talk to your underground Chinese nav manufacturer or check boring naviextras).
3-They give 7 days trail serial for wince or Android so you can test their software.
4-They cover all world maps.

What I don't like, is that their software is very poor and basic.

Finally, NNG and Sygic people if you are here can you please do like Desnav and I assure you will make a good revenue out of it.
