Some older el-cheapo GPSs had a built-in 100MPH limit to PREVENT you
from using them in planes. It isn't that the GPS engine couldn't do it,
they
just didn't want to take business away from their (then) $1000 units.

As I understand it, that mis-feature is pretty much gone from newer GPSs,
even
the cheapest ones.
