Take original gopal menu.exe in root of My Flash Disk on device, rename to mnavdce.EXE.
Go to My Flash Disk/Navigation, rename mnavdce.EXE to mnavdceorig.EXE
Move newly renamed mnavdce.EXE from root of My Flash Disk to navigation folder.
To get sound and power Settings, etc to load at boot (which they must), go to My Flash Disk/Navigation and rename (already renamed from menu.exe and moved from root to ../navigation folder) mnavdce.exe to mnavdce.NOexe.
In same folder (/navigation) rename audiomanager.exe to mnavdce.exe.
Rename mnavdce.NOexe to audiomanager.exe.
Reboot.
Reasons for all the renaming, etc:
Gopal is hardwired to run menu.exe (from root of My Flash Disk) and audiomanager.exe from ../navigation folder.
Now both (original) menu.exe (now moved and renamed to audiomanager.exe) which loads the power/sound settings) and the new GPS Menu (in root of My Flash Disk) automatically start.
In Task Manager, they will show under their new aliases.
It is necessary for the original GoPal menu.exe (now called audiomanager.exe) to run at startup (which in turn triggers other modules and settings to start).
Then use any shell/menu you like as long as it can be named 'menu.exe' to trigger it...located in the root of My Flash Disk.
To run GoPal Settings (FM Receiver, Power Settings, etc), setup a shortcut (Button 3) to run My Flash Disk\navigation\multimedia\GoPalSettings\GoPalSettings_np.exe
