Is this just a fact of life with GPS computers? Or am I missing something?
Part of the TBT glitches are frequently due to map data base issues. I suspect that ALL on-line based maps have inaccuracies of what they think exists in an intersection or section of road and what is actually existing. Thus the units can get confused.
As well and the nature of GPS is there's a built in delay from when the unit can calculate position from the satellites to what it shows you on screen. Many comments have been written about folks trying to navigate a round-about or a series of frequent turns in a city, where the unit cannot keep up with whats happening in real time. This happens in car units as well, as BTW.
