FR-S BeSpoke Pioneer radio diagnostic screens
 

Hey does anyone know how to access the diagnostic screen on the BeSpoke audio system on the FR-S? That's usually the first step in getting things like custom boot images and such loaded in to the headunit. I haven't found anything in the owners manual or on Google for that matter. Anyone have an inside line at a dealership service center who could find this out?

Did you ever find out anything on this?

I need this 2

anything? I would like to change the boot image of the screen.

Hold the "Audio" button and flip the parking light on/off three times. I can't find where I saw this, but I confirmed this works.

Boot image on the FR-S is unchangeable. Just spoke to Scion. Still digging though, as I really want to change mine.

what exactly will this do?

Puts the head unit in diagnostic mode. As to why you'd want that, I don't know. I explored it and couldn't find anything useful.
