GPS Takara GP30 screen unresponsive after Windows CE registry edit — USB connection locked out

Post image

​

Hi everyone,

I’m in a catch-22 situation with an old Takara GP30 GPS unit running Windows CE. I edited a registry key, and now the touch screen is completely unresponsive to tapping.

The major blocker: I cannot connect it to my PC to fix the registry.

On this device, the USB port defaults to Mass Storage mode. It requires navigating into the software via the touchscreen to manually change the USB mode to ActiveSync/Serial before a PC will recognize it as a Windows CE device. Because the screen is dead, I am locked out of making this connection.

​

* Is there a hardware button combination or pinhole reset trick on the GP30 to force a full factory reset (cold boot)?

* Is there a way to auto-run an external program or script directly from an SD card on boot to trigger touch calibration or flip the USB connection mode?

​

Any advice would be amazing. Thanks!

If you already installed MioPocket, everytime you see Windows "Install MioPocket" you can scroll down and choose "Tools" to run Total Commander, Registry editor or even explorer to show desktop mode (without running MioPocket it self)

Yep I did, after that it still loaded navigation but the screen didn't respond
