I stumbled upon this and was very interested. Even more when you guys started rooting it. Not trying to be rude, but unfortunately this just seems to be old, outdated and slow consumer grade hardware.
Another question I'm asking myself: Where is the difference between one of these random chinese headunits and this avinusa model? Seems to me they are just reselling for a higher price.
I was really excited for this to work because I have the old CHAMP2 headunit but seeing the thread linked above the aspect ratio is completely off.
Anyway, I basically just wanted to give you guys the link to the thread and wish you the best of luck to make something useful out of this
