Honestly, I wouldn't know. I can't find much information about the specifications.

Not positive, but uses WinCE 6. Do a Google search for MioPocket. However not sure it will work for your device. Maybe though.

Saw this regarding MioPocket and your device:

I changed the script to test if toolhelp.dll was needed before it copied it everywhere. That's fixed my problem with the NAVMAN MY75T.

I suspect what actually fixed it was just the checking process SupportsProcHandling(). My theory is that this command forced the toolhelp.dll to be loaded and allowed all the other proc handling code to work.

For Reference I changed the lines in mioautorun.mscr (auto.mscr for Navman devices) that copy toolhelp, to the following lines of code.

WriteFile(InstallLogFile, "MioAutoRun.mscr: Checking the System Supports process Handling...^NL^", TRUE)
WriteFile(InstallLogFile, "MioAutoRun.mscr: SupportsProcHandling = " & SupportsProcHandling() & " ...^NL^", TRUE)

If (SupportsProcHandling()=TRUE)
WriteFile(InstallLogFile, "MioAutoRun.mscr: INFO: The System Supports process Handling...^NL^", TRUE)
Else
WriteFile(InstallLogFile, "MioAutoRun.mscr: Warning: The System Does Not Support process Handling...^NL^", TRUE)

#Copy toolhelp.dll to \Windows so that the ProcExists commands in this script will work
If(SystemVersion("major") = 6)
WriteFile(InstallLogFile, "MioAutoRun.mscr: Copying CE6 version of toolhelp.dll to the system...^NL^", TRUE)
Copy(SystemFolder\"CE6\toolhelp.dll", "\Windows\toolhelp.dll", TRUE)
Else
WriteFile(InstallLogFile, "MioAutoRun.mscr: Copying toolhelp.dll to the system...^NL^", TRUE)
Copy(SystemFolder\"toolhelp.dll", "\Windows\toolhelp.dll")
EndIf
EndIf

If(SystemVersion("major") = 6)
#If CE6, replace all copies of toolhelp.dll with the CE6 version, since MortScript crashes with the pre-CE6 version
WriteFile(InstallLogFile, "MioAutoRun.mscr: Copying CE6 versions of toolhelp.dll to miopocket...^NL^", TRUE)
Copy(SystemFolder\"CE6\toolhelp.dll", ProgramsFolder\"toolhelp.dll", TRUE)
Copy(SystemFolder\"CE6\toolhelp.dll", ProgramsFolder\"MortScript\toolhelp.dll", TRUE)
Copy(SystemFolder\"CE6\toolhelp.dll", ScriptsFolder\"toolhelp.dll", TRUE)
Copy(SystemFolder\"CE6\toolhelp.dll", SystemFolder\"toolhelp.dll", TRUE)
Copy(SystemFolder\"CE6\toolhelp.dll", SystemFolder\"Extra\toolhelp.dll", TRUE)
If(FileExists(SkinFolder\"SystemInformation\MyApps\toolhelp.dll"))
Copy(SystemFolder\"CE6\toolhelp.dll", SkinFolder\"SystemInformation\MyApps\toolhelp.dll", TRUE)
EndIf
Else
#If not CE6, restore all copies of toolhelp.dll back to the CE4 version
#(in case you have both a CE5 and CE6 device using the same SD card)
WriteFile(InstallLogFile, "MioAutoRun.mscr: Copying CE4 versions of toolhelp.dll to miopocket...^NL^", TRUE)
Copy(SystemFolder\"CE4\toolhelp.dll", ProgramsFolder\"toolhelp.dll", TRUE)
Copy(SystemFolder\"CE4\toolhelp.dll", ProgramsFolder\"MortScript\toolhelp.dll", TRUE)
Copy(SystemFolder\"CE4\toolhelp.dll", ScriptsFolder\"toolhelp.dll", TRUE)
Copy(SystemFolder\"CE4\toolhelp.dll", SystemFolder\"toolhelp.dll", TRUE)
Copy(SystemFolder\"CE4\toolhelp.dll", SystemFolder\"Extra\toolhelp.dll", TRUE)
If(FileExists(SkinFolder\"SystemInformation\MyApps\toolhelp.dll"))
Copy(SystemFolder\"CE4\toolhelp.dll", SkinFolder\"SystemInformation\MyApps\toolhelp.dll", TRUE)
EndIf
EndIf

Did you install it as instructed?

Can you access the device with a PC as normal?

Did you make a full backup before starting?

This error can be caused by using the wrong toolhelp.dll, Buried away in the mioautorun\system folder are dll's, workout what WinCE version you have, then copy the toolhelp.dll from the system folder for WinCE 5 or the system\ce6 folder for WinCE 6, place this dll in the root directory where Mortscript.exe is and try again...
