I recently tried to update my z140BH to the new 4.6 firmware but ran into a problem. After the update was finished I cycled my ignition, screen went black and the unit never power back up. Now im getting no sign of life from the unit. I really don't know what to do at this point. Any help is apprectiated!

I'm wondering if there is a service mode, a sequence of button presses/holds, or a way to boot from an external source.

Yes - search for TestMode. But the HU must be functional and you need to be able to insert an SD.

Any way of resetting the unit?  I have the same issue.  Disconnected HU, battery, removed and reinstalled... nothing.

 

Does anyone here know what to do at this point?
