Wow that looks really straightforward. Thanks! Maybe I'll get a chance to try it later this week or this weekend. If you try it first, let me know!

According to the docs, you have to issue these commands to get the dev board to route from the I2S connector:

SET CONTROL AUDIO INTERNAL I2S EVENT 32
SET CONTROL EXTCODEC PRE 30 18 0200918000008A1037000100008000000FF07C7C787C7C78 30 04 25C01400 30 0a 28C00000000000008000 30 03 330F00 30 05 3F00800F00 30 04 6500A200
RESET

In the meantime, I'm having a devil of a time trying to find out how to get high-ASCII characters to appear on the car stereo screen. I can't find the bluetooth specification information for how to handle non-ASCII characters in the strings sent up in the AVRCP metadata.
