In my android radio version, I didn’t see anything like “R0..” When I choose version of canbus “raise” -> psa/Citroen -> I have only models of car and I get C4L. Everything works like steering wheel buttons but I have problems with resetting displays and appearing diagnosis.
on the screen where you select the RAISE>PSA/Citroen is there an app update button on the top right corner? (mine has which is where I was able to update can.apk)
