That is correct, the GID version won't allow you to change the comports, because it will expect the GPS settings Icon to be activated and "manage GPS automatically selected"
please check if you have configured your device for GPS splitting using the GPS Settings icon from your "settings" in your device.
If all else fails, reset, re-install version 1.52 as that one is confirmed to work in another thread in this forum, search for TyTn.
We WILL get you ontrack, no-one is left behind :)
