Saeidf Posted August 2, 2023 Report Share Posted August 2, 2023 Hi Everyone, Apologies in advance if the posting is in the incorrect place. I recently Imported a JDM Landcruiser to Canada and the car comes with a Pioneer Carrozzeria AVIC-MRZ007 (picture for reference). The unit is obviously a Japan-Only product and hence it only comes with a japanese UI. Searching the web I found a procedure to change the language file in test mode on the MRZ07/09. However, applying this procedure the MRZ-007 seems different as accessing TestMode requires pressing a Righ and Left Track botton which the MRZ007 does not come with. I tried contacting Pioneer Japan for help but they just kind of shooed me off saying they will not allow me to access the test/service mode. Can somebody who has experience with this unit guide me in the right direction please? I would prefer to just keep the head unit and use it as is rather than replace it with another. Any help would be incredibly appreciated. Quote Link to post Share on other sites
RonS Posted August 3, 2023 Report Share Posted August 3, 2023 I have no experience with this unit or the process to convert to another language. However I assume that TestMode must be triggered by hard buttons since it must be able to get into Testmode while/before the unit boots. So - did you try pressing - and + while booting? I don't know about those other hard buttons since I don't recognize the symbols. If that doesn't work, I'm sorry I have no other ideas. Sooner or later someone who has done this will see your question and give a definitive answer. Quote Link to post Share on other sites
