Missing ECUs in TAL-Matrix

[samak89]

Hello, I was wondering if someone can help me. I am thinking of updating my headunit from id4 to id5 so that I can get Apple CarPlay .. My question is …once the headunit flash has completed, there will be a black screen displaying a message saying “No Signal”.  I am aware that you have to code in the values for APIX/COLOR/MODE using launcher pro to fix this. Will I be able to code in these values without any issues or will VO be locked which will prevent me from coding it? Thanks !
