2018 headunit customization
 

i recently purchased a 2018 brz ts and was wondering if there was anyway to change the startup screen and wallpaper to something other then the default one. i know it was doable in the older headunits but i havent been able to find any info on how to do it with the new ones.

I'd be happy if you could just startup with no audio... And I haven't found a way to modify the startup screen either....
