Why Not Built In GPS
I agree that it would have been great to have an internal GPS receiver. Or, if nothing else, offer it as an option that can install inside the radio. Similar to the CTCSS and pre-amp option of the BC760 era. Certainly it would add to the cost, but the GPS receiver itself isn't that expensive. As far as receiving GPS signals, I think having an external GPS antenna plug would have solved that, since it would allow an external GPS antenna to be used.
