I rented a brand spanking new Camaro today, had 4.8 miles on it! It has what seems to be the free new car trial sub on it. Otherwise it costs 7 bucks extra. Which satellites are being used for reception? There was a few places today in Portland where I would normally get terrestrial signal and not lose contact but in this car I did. Any car I rent with sirius it sounds like the XM feed. The last few letters of every word sizzles like it's on fire. I've had both since 2006 and remember what each service sounded like. The sirius sound is soft but muddy and xm is crisp but metallic sounding. At least to my ears. Thanks for the info.
