I downloaded that version of nextgen iGO Navigation 9.18.27.693527 - 14.mar.2017. skin Pongo
Everything seem to be perfect but I have only one problem: I start the navigation and the programme still "...looking for GPS connection..." even if I see that it found 4 or 5 satellites.
Finally the programme close by itself.
I installed on 7" in internal memory android tablet 4.4.2 JB made in china.
Please help.
