GPS automatic volume lowering for directions
Wasn't sure where exactly to put this thread or what to title it but hopefully the right people find it. I am trying to find software (or the proper way to code something myself) so that when the GPS software on my carPC gives an audible direction, every other volume source (music, video, etc) is either muted or lowered. I would just like to know if there is already a solution that exists for this and if not, how I might go about creating one. Let me know if that makes sense as it would be really cool to implement this. I know I have seen it in OEM nav units so imagine it is theoretically possible.
BTW I am using Windows XP and two specific programs I want to control are iGo8 (navigation) and Windows Media Player (music) but I figure a solution should work for any software really.
