Back from the dead, is this thread.

I'm getting a motorcycle GPS unit soon which will send voice navigation through A2DP. I wanted to be able to hear this, along with the music on my N900, using earplugs inside the helmet. So digging around, I came across a couple of things. The first is general directions.

The second is more specific.

I made it up to step 5 (running CSSU devel, had to install d-feet and pulsaudio-utils) but since I don't actually have the GPS unit yet, the rest will have to wait until later.

If anyone is still interested in this idea and wants to give it a try, I'd love to hear how it does.
