Greetings, new guy here, great site!
Been thinking about a D3 for my Saab 9-3 and have been poking around this site for a bit. My Saab came equipped with OnStar but I have since disconnected the service. Curious if I installed a D3 if I would be able to use the OnStar antenna to facilitate the D3's GPS? This option seems a lot less painful than installing a new antenna. I've installed a car stereo or two in my day, this one just looks a little more advanced w/GPS, etc.
Thanks.
