So Santa dropped off an XM kit for the Cobalt this Christmas. So I had a question for anyone who has installed one of these before. Is it worth it to get it professionally hardwired in, or should I do the DIY hookup to the FM antenna? I'm going to keep this car for a long time and I spend a lot of time in it, so I want it to be done right, but I also don't want to spend extra money if I don't have to.
Thanks for your opinions!
