Gps + alp

Sounds like BRD is saying it most likely will perform as if there were no pre-defined speed limit, like Savvy does I'd guess.

That is right. If you have GPS enabled but your GPS mouse is unpluged/or GPS signal is not locked - your ALP will behave as if your GPS setting is disabled. If your antenna is plugged in and GPS signal is locked ALP will use speed reading that it gets from GPS whatever it may be.
