crankz Posted June 9, 2015 Report Share Posted June 9, 2015 Hi, i also own a MRZ99 Unit. I bricked mine, cuz i tried to replace PRG0 and PRG1 (And BOOT Folder <-- this bricked mine, to a Splash-Screen Bootloop )However, you can enter Test-Mode by holding the NAV Button (left japanese button in the middle) and pressing right --> left --> right --> left --> right --> left and then release the NAV Button. Unit will restart in Testmode. But be careful! Good Luck Quote Link to post Share on other sites
Nismospirit Posted June 15, 2015 Report Share Posted June 15, 2015 What would the chances be of a member having some back up files of the PRG0 and PRG1 for any of the MRZ series on this forum? Thanks Quote Link to post Share on other sites

dzo Posted November 13, 2016 Report Share Posted November 13, 2016 If anybody is still interested, here's a testmode key for the mrz99. Unzip it and put TESTMODE.KEY in the root of an sd card or usb drive. This gets you into technical mode so there are more settings than if you use the key combination. testmode_mrz99.zip Quote Link to post Share on other sites
Wazza99 Posted November 29, 2016 Report Share Posted November 29, 2016 AVIC MRZ99 - Does anyone have any ideas on how to release the front cover to access disc and SD slots. I press the eject button but the unit just beeps a few times and nothing happens. There is no disc in or card in at present. I would like to try and mod the language as suggested but can't access the SD slot to get started. Quote Link to post Share on other sites

Распакуйте его и поместите TESTMODE.KEY в корень SD-карты или USB-накопителя. Это приводит вас в технический режим, поэтому есть больше настроек, чем при использовании комбинации клавиш. testmode_mrz99.zip Привет!
