Has anyone researched the possibilty of writing code to dynamically adjust music volume based on GPS speed of vehicle. I must say, that is the one thing i miss from my stock radio.

the unit already does it for navigation prompts... one would think we could tap into the volume function and write a script that monitors the GPS speed.. and maybe can have guidelines for % change of volume per MPH?

I'd like to have that also

No one knows? I also really like this option. Its very annoying to in/decrease the volume while driving...

There is no way of doing this unless someone reverse engineers Pioneer's software(Not the iGo), as that is what controls everything but the iGo software.
