Can you explain what you're trying to accomplish? Are you installing an aftermarket head unit? ThunderBolt ? 2
I have been looking for it as well, looks like I will just do the $15 2day pass to TIS and download it all. I am trying to retrofit a 2012 prius 2 radio into a 2010 prius 2. I thought with just power and spk plugs connected it would wk. I get no audio out at all, of a supposedly brand new radio that was a take out for a nav sys install.
Were you ever able to figure this out? I am trying to do the same. No audio out and no steering buttons with stock wires.
