Looks like Phatnoise might be reading this website as I got a quick response.
"I spoke to our technician, Sylas. Unfortunately, your PhatBox will not boot up in our development environment and cannot be repaired. We apologize for being unable to assist you. We do not stock or distribute Audi/VW Edition PhatBoxes or PhatBox parts. If you would like to have your PhatBox returned, please email your shipping address to stseng@harman.com."
Since Phatnoise nor Harman support this product, does anyone know where to go for repairs?
