Are the GPS settings hard-coded in these ROMs?

[x99percent]

I have been trying, without success, to configure my external bluetooth GPS. Why? Well, because it works MUCH better than the internal GPS on my phone.

The problem is that the settings in "External GPS" on the "Hardware" tab will not accept any changes. No matter what I try setting them to, they always revert back to COM4 and Baud rate = (None).

I have tried selecting "GPS" and "no GPS" when building a ROM in the kitchen. I have also tried 5060 and 5067 ROMs.


Is this stuff hard-coded into the ROMs? If so, WHY? I should be able to configure my phone to use an external GPS even if I have cooked a ROM that enables the internal GPS.
