So I got the LX model of the 2016 Honda Civic which has the 7 inch screen but did not include serious XM radio. I would really love to add it into my current radio and not have the Xm receiver docked somewhere else in my car. Has anyone added XM to their vehicle yet through the factory radio? I assume it can be done seeing that some models come with them, but my local Honda dealer told me the only thing I could do is add a receiver.
