thanks to somniac, i got a bit further on my u310bt, (not using condi hackmode stuff... i just want switchable nav between igo and stock.)
I suspect NEventWatcher.exe may be lockign the comport.
I was able to do a basic test with a mortscript to do a simple reg change followed by a reboot to "remap" the comport and take it away from stock nav. If i intercept HMIManager after the hack and load igo8, it works and sees comport on 4. However, if i do that, none of the control overlays/daemons have loaded yet. So then I intercept something further downstream - like navi.exe, and i see the av controls/overlays, but then igo8 doesnt completely load up (crashes i think with access violation).

currentport = RegRead("HKLM", "\Drivers\BuiltIn\GPS_HWCOM", "Index")
If (currentport = 2)
RegWriteDWord("HKLM", "\Drivers\BuiltIn\GPS_HWCOM", "Index", 4)
Reset
EndIf
Run("\Storage Card\iGO8\iGO8.exe")
perhaps i need to intercept further upstream or maybe different exe friend of hmimanager
