Did you get that to work?
I followed the instruction posted on here to flash over the fx3.1 files (https://mega.nz/folder/zxk03JJT#o2b_QPi1_CyTaRTbtMe4zg) and am able to get the head unit running but there is no bluetooth firmware. when I go to update the firmware it shows nothing as installed. Also when I look at the device info in the windows explorer it shows up as 'avic-f700' not 'avic-f700bt'. It looks just like the one in imyeremy's picture - with the led BT indicator on the bottom left, I'm pretty sure it should work.
Any recommendations on how to add the BT files
