[aprssig] could we

[William McKeehan]

I did a quick Google search for "OnStar Technology" and found this article:
http://www.edmunds.com/news/innovations/articles/43031/article.html which
gives a basic overview of how it works. It mentions that they use Satellite an
cellular communications.

The Technology & Hardware FAQ page at onstar.com
(http://onstar.com/us_english/jsp/faq/not_faq_main.jsp?topPage=not_faq_techhardware.jsp&id=5&title=Technology+%26amp%3B+Hardware)
gives some more details.

Hope this helps.
