Does the Onstar system require an antenna and does anyone know what it looks like?
Nope, that's the XM antenna. OnStar does reqire an antenna so far as I know. I googled OnStar antenna under an image search and came up with a page with a Subaru that has one on it. I tried to grab the pic and post it over here, but the file is too large. It kinda looks like a little... er... manhood.Frosty said:http://www.solsticeforum.com/photopost/showphoto.php?photo=443&sort=2&cat=3017&page=1
Check out the picture in the above link; the black pimple in the middle of the trunk is the antenna.
Now that would be über ugly.NytLyt said:On several new GM products, they have a combination XM/OnStar antenna. It has the flat base of the XM with a short riser of the OnStar. The Solstice may use one of those so you would have a sharkfin in place of the pimple.
