sorry if I post it in the wrong section but I wasnt sure where to post otherwise for a H series...



Does anyone know how to get into test mode for AVIC-HRZ099? I would like to see if it is possible to do a similar language hack like the MRZ99 units.


Many thanks!




Hi guys, any success on this unit?

Why can't I see any replies

There weren't any replies. Probably because no one who has seen your question knows the answer.

Did you try searching for the answer?  Try http://avic411.com/index.php?/topic/39638-avic-mrz99-custom-firmware-testmode/&do=findComment&comment=341665

BTW, I have no knowledge of how to convert Japanese units so I won't be of any help
