Hi, thank you for all that help. Appreciate you took the time.
So I tried all that as your wrote. No success. I also followed your method and searched for other Control4 files for this model and others. Nothing worked.
Actually the proper MRX720 Control4 file was in c4z format, not as c4i. I was unable to take out the MRX720 codes from the c4z file. Do you have any means for that ?

Thank you for all the help you provide.
