Hi RonS, please forgive me for acting in an unpleasant manner and in doing so inadvertently broken rules of this forum.

Hello there, any one please?

Hi, I have AVIC-HRZ900 on my car. I would want to change its menu texts from Japanese into English. I know the map may be a challenge to change to another country, but at least I wish that its menu can be readable. I've read somewhere in this forum that some users have successfuly converted their MRZ99 into English. Do you guys know how to put HRZ900 into test mode? I wish to try the method performed on MRZ99. Has anyone been able to convert their HRZ900 into English? Would you please share your method? Thanks in advance. rdvb
