So my Avic-Z1 was having issues locking up frequently.
Thought a Upgrade would at least not hurt anything.
Tried an update.
Was getting a consistent error.
Hearing the distinct noise of the Hard Drive clicking.
So after talking to Pioneer. And not relishing the removing the whole unit for some unknown time.
Thought I would go with a new hard drive.
New Hard Drive. Pay Garret Toomey by Pay Pal.
2 days later a new drive with a torx tool arrives.
15 minutes later old drive out, new drive in.
AVIC-Z1 updted to the latest maps, and Firmware.
System no longer locks up.
