I just bought a 2006 Honda Accord which has XM capabilities. I signed up for the 3 month trial and am deciding whether I want to keep it. I have had a Sirius subscription now for 5 years and am currently using a Stiletto 2, which I love. I had a pioneer cd player in my old car which I had my Stiletto 2 playing through with a sirius antenna. I think the reception was better before with the Sirius in the old car than the XM in the new car. Don't know if Sirius gets better reception where I live or if the factory installed antennas that Honda uses aren't as good as the ones you buy from Sirius. What do you think?
