Navman MOVE75 Unlock and (install) iGO

This work enables you to unlock Navman MOVE75 and install iGO on it.

How to unlock a stock device

Browse to Program Files → Navman. Then either:

Replace AppStartupSec.exe with Total Commander (AppStartupSec.exe.tc), or
Modify appstartupsec.ini to run your apps

How to run iGo on this device

This device goes far and beyond not to allow running iGO, so to work around this issue, MortScript was employed.

This is likely a vendor restriction.

To work around the issue,

Copy all files to the device.
Copy iGo packages to (device root)\IGO\ . So iGo must be in (device root)\IGO\Navi.exe
Append your (device root)\IGO\sys.txt with data from (device root)\IGO\sys_required_params.txt

This step is required to mitigate bugs

Startup sequences comparison

Normal startup: Bootloader → ??? → AppStartupSec.exe → (multiple applications including) Navman
Quick unlock: Bootloader → ??? → ~~AppStartupSec.exe~~ Total Commander
Unlocked startup (this repo): Bootloader → ??? → AppStartupSec.exe → (multiple applications including) ~~Navman~~ MortScript Autorun → MortScript (custom autorun.mscr) → modified iGo initialisation sequence → iGo

Known issues

[worked-around] iGO does not run from the first time.
- MortScript workaround applied.
[replaced] The device does NOT work with PowerM. Fails at line 216. No known fix, but a MortScript workaround was applied.
[worked-around through PowerOff] The device will NOT sleep (suspend, hibernate) properly, as the device will fail to jump back into iGO. This is because iGO is being launched from MortScript, which the system does NOT go after sleep as required for the proper functioning.
- Therefore, step 3 is required to mitigate the issue.
- MortScript workaround for PowerOff applied.
