thanks djeman
I tried your last revision iGO_9.6.29.596752_dj4a
and it works ...

here are my steps for other Note4 users:

1- installed the app iGO_9.6.29.596752_dj4a ..... ran it .... it gives a massage ..... "insert the memory card"
2- in the externalSdCard, I put the iGO folder into >>> /Android/data/com.nng.igoprimoisr2013march24.javaclient/files
3- again I installed the app iGO_9.6.29.596752_dj4a
4- I modified sys.txt by adding :
[2d]
traffic_lights=1
use_flat3d=1

5- I deleted save file and device.nng ... from IGO folder ... if any.
6- run iGO app



I will try iGO_9.6.29.596752_dj4b and report back later.



djeman you are the man
