Hi
So just to give you all an update, it is not my "head unit or device" at all as mentioned, it is the iGO Nextgen Software itself.
I tried heaps of adjustments and sys.txt settings with no effect i un installed it and tried a couple of other programs, Sygic latest build and HERE WeGO and both worked fine
I have successfully installed the latest Sygic Version without a hiccup and sound dims when i go over speed limit and other alerts pop up.
So goodbye to iGO Nextgen..........
