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

Thanks to tonyfussell

The code test what version of windows CE is in the device 4 or 6?And copy some files?Im gonna use the MioPocket to unlock the Gps?Where im gonna use your code?Thanks for your help.

I PMed you.

MioPocket installation instructions [Please Register or Login to download file]

When i try to install, he do the install but when reboot show application error application MortScript.exe encountered a serious error and must shut down

Which version of miopocket did you install?

MioPocket 4.0 Release 68

Did you install it as instructed?

Can you access the device with a PC as normal?

Did you make a full backup before starting?

Yes, he do the install but when reboot show the message "application error application MortScript.exe encountered a serious error and must shut down".I can acess the device normal with the pc.

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...

Where i can see my version of windows ce?I found 2 toolhelp.dll one in ce6 folder and other in the ce4 folder. ce5 folder dont have any. I test with 2 toolhelp.dll and didnt work.
