Not so.  There has been a written form for Navajo for the last
few decades (at least).  It uses the Roman alphabet but the mapping
of sound-to-character is not the same as for English.  Vowels aren't 
even a, e, i, o, and u, which certainly doesn't help speakers of English
trying to form syllables.

To my eye, it more closely resembles modem noise on an ASCII terminal 
than anything else, but it does exist.  (no, I can't read it)

Navajo code talkers spoke with Navajo words, but not with Navajo 
meanings.  Parts of speech that should be nouns became adjectives,
etc.  Navajo Elders who heard the code talkers commented "It
sounds like Navaho, but it doesn't make any _sense_!".
