So the system SD card for the head unit in my car (Vitz '10) was missing, I searched PW and found the correct system files to use and got my unit to go past the initial screen.
But now the unit is asking for two new types of inputs. First one i have no idea about and the second one is the ERC code. Can anyone who is experienced with these systems suggest what I can do? Each headunit has a unique code on the erc screen which i cannot figure out.
I have searched online but only found people selling the codes for $25+ so there is definitely some way to get these codes. Also going to an audio shop is a last resort for me as I want to try and figure this out for myself first.
I would really appreciate any help as I'm sure a lot of other people may be facing the same problem who will need info on how to get the codes.
Attached are images of the two screens which ask for codes.
