Will your harness be able to make the hifi recode possible?
You need to establish first of all which HU you have.
You may have this headunit
Can you confirm if you have this headunit?
I reckon its to do with your HU and if you have headunit like the one in the link above, then you cannot code it to hi-fi.
Your other option would be to change your HU to 'professional' OEM headunit.
