Some of them don’t speak any Spanish at all. Some speak Indian languages only.

Yes, you are right, most inland natives speak a language other than spanish although some spanish words have found their way in there.

In this case though I can understand enough "spanglish" the official border language. This woman had a distinct accent and didn't know words for things associated with technology.

There was a lot of pointing at "ese cosa". "Los cosas" BTW were the cable decoder box, remote and coaxial cable. It appears the woman did not know how to link everything together.
