I have spent a year waiting for someone to say they have either managed to load Z1 North America Image onto the JAPANESE HRZ 09

So far no one seems to either confim that the z1 firmeware works or it does indeed brick this unit.

 

Here is what I have discovered:

 

1. The AVIC HRZ 09 is very similar to the AVIC Z1

 

 

1. The System Test Disc doe indeed work on this unit
