Welcome to the forum.

edf, Yes this is where that particular mod was introduced, nomad (the software developer), first muted the idea here and most of the development/testing was done by forum members.

Look here in the POISon thread (re; POI-Sound), it has all you need to mod your map disc and mod the OS to accept the sound alerts.

P.S there is a pre modded version of the OS in the thread somewhere, but it has other mods as well, (sky,pointers and splash), so download and use if you like (or not).

You will have to do the other mods yourself as you will need a copy of the 2009-1 map dvd (or cd).
