Is there a hack that will allow the stereo to adjust volume based on road noise or speed? I've read that you can adjust the navi voice volume based on speed, but what about music? Thanks.

Anyone know if this is possible or done already?

I'm not quite sure if this is what you're looking for...I just installed my F700 yesterday and I remembered seeing a setting for Dynamic volume? it had bars for the min and max speed. Not sure what it's for yet just starting to get ready to mod, making backups of my stock files now...

Speed increased volume only affects nav voice. No none hacks to affect music volume at this time.
