I would be ripping my car apart if it was at least 40F not the 9F it is now
40F is shorts weather in Chicago
Since i have a 2010 i heard that there might be a chance that i might have 2 coax wire going to the onstar
like in this item

when i look at it i seem like that bluetooth piece is just a antenna covering a coax plug.
not sure it it will work but i would like to upgrade the onstar to a newer one, i think the new one have bluetooth in the mylink radio now.
