2004 H2 - What is This?

[Hummertime]

ah... finally a subject in my area of expertise. the onstar system is analog cellular which is a dying technology. mostly carriers only have it because they are required to by law, to service older customers who for whatever reasons have not updated to digital equipment. it seems to be the best service because of the roof mount antenna and full 3 watt power(handhelds limited to 6/10ths of a watt)capability. however,analog systems can only carry a limited number of calls and are not very secure. yes,they can be scanned very easily. ONSTAR IS NOT SATELITE PHONE,only gps is used to track vehicle location.

Bone stock but dreamin!
