I wanted it for PDA. I got it working, here's how!
1. Connect to your computer using Windows Mobile Device Center.
2. Select "WindowsCE" from My Computer and go to ResidentFlash.
3. Open "autorun.inf" and change it to "/Windows/explorer.exe" (without quotes or spaces) and save it to your desktop.
4. Copy it to ResidentFlash and select 'Copy and Replace'.
5. Delete the "DShell" folder, it is not needed.
6. Copy MioPocket to a NON-SHDC SD card. Copy just MioAutoRun.exe, MioAutoRun.mscr, MortScript.exe, and the folders Media and MioAutoRun.
7. Disconnect GPS and power on. It should go straight to the Windows CE Desktop. Cool!
8. Insert your MioPocket SD card now.
9. Go to "My Device" and tap "SDMMC". Then, select MortScript.exe. It should say something along the lines of "extensions registered". Now select MioAutoRun.mscr.
10. MioPocket installation will now start! Follow all the steps, then your device will reboot. Now, you have a MioPocket Nextar!
