What is the current status on cracking the new Z series units? Has anyone accomplished anything substantial?

The modding community for the F series was pretty successful, I'm surprised nothing has been going on with this series.

It's sad that Pioneer releases these units with such blatant user interface design flaws. Such as having to change to map mode, press OK, and wait for the VR dictionary to update before being able to use voice recognition, every time the unit reboots. That takes a full minute of your time and attention and completely defeats the purpose of VR on short drives.
