I've had my Z140 now for 2 years and it's worked perfectly until now.  On Friday, I got into the car and started it up and it booted up to what seemed to be normal.  Then it got to the screen where I have to select 'OK' to the use of navi warning.  I selected ok and it just stuck on the screen for awhile then turned black.  If I select 'mode' it takes me to the audio page and the radio works and my iPhone works if it is plugged in.  However, bluetooth and sirius no longer work.  Also if you go to the Home screen none of the touch buttons work (so I can't get into settings) and it goes to a black screen again shortly.  I just select mode again and I can play audio.  The system will also shutdown on me and restart every 30 minutes while driving.

 

I unplugged the battery, have ripped out the entire unit and unplugged everything and replugged it in, checked all the wires (seem to all still be connected), and reset everything to factory settings.  Still no luck.....

 

I have not used any hacks besides the parking brake bypass.

 

Has anyone had this issue before or have any ideas?

 

Thank you!
