Thanks for your comments. I know the responsibility lies with me. And I'm willing to give it a try.
My thinking tells me that NNG should not have different exe files for all different multimedia devices as long as they are on WinCE. (Exes on Android, İos etc are different for sure). ZENEC on this thread shows 9.19.584533 and mine shows 9.18.23.572746. As long as one is not interested in playing around with modifications, ux and system.ini files etc the exe should be the same. If this is true, if I keep the whole navigation folder intact and change only the exe file from this thread (backing up the original one first off course) it should work. Am I wrong to think that?
One more question if I may,
Again from the old Avic411 times I remember we were able to change the speedcam warning sound alert5!.wav in the audio folders. I couldn't find this in the nextgen software. Does anyone know how to do this?
Many thanks.
