I know this has been posted before, and probably a lot, but I did some searching on the forums and through Google and couldn't find any of the posts I've seen in years past.
I recently put my CarPC back together and updated RR, kept the DFX4.0 skin, but one setting that I no longer have is the lower music volume/mute when the GPS (IG4) is talking. I remember there being some code to place in the exectbl.ini for this. So I need that code, and I forget which instance of the ini file do I put it into. The skin one, or the one in the root RR directory?
