So if you need help from an area that does not have cell service, you really have a problem. Remember early commercials where they showed it bouncing signal from satelite, back when cell phones were very few or did not exist. Also XM no longer, if they ever did, use the SATCOMM system. If GM really cared they'd convert the system to something more modern and fix no signal issues for XM and Nav.
