AVIC-MRZ99 Custom Firmware / Testmode
in Hacks/Mods
Posted
Hi..I have a AVIC-MRZ05 trying to see firstly if the language change you described above for MRZ99 will work for mine. I have got to testmode but am not sure how to back up USER file..could not find reference on here how to do this. next question is I looked in USER and seem to have both PRG0 and PRG1..(I attach some photo's. I also see from other posts that pasting new file may be an issue....If you could help with step by step process on what I need to do that would be great. I have copied the zip file you have link to on SD card already..(though did not seem to show on screen when I put it is SD slot...my be when I am in testmode it will be seen..but not sure how to retrieve it from SD card and paste it on system....If anyone has done this on AVIC-MRZO5 it would be great to know it can be done and step by step process. many thanks
