I have had XM for close to a year and was exicted when they announced back in Feb or MArch that all music stations were going commercial free. Well big friggin deal they still plug for other stations and what not on them, just no mortgage commercials or anything like that. All in all coverage has been great, sound quality has been top notch as well. As stated above I have to agree driving down the highway at 70+ MPH with windows down i seriously doubt you would notice or care if something was a 128 or 320 Mp3 quality stream.
The addition of the traffic stations has been of no interest to me at all I just never tune to them. The 4 sporting stations are all great ESPN, ESPNews, FoxSPorts, and Sporting News radio all kick ass. College football is here and I get Pac-10 ACC and Big Ten games each Saturday but am left traveling to a friends to watch the NFL games on DirecTV (no NFL for cable or XM users
)
When I first got my unit I was looking into either, but just so happened to purchase a Pioneer head unit to put in my '96 Taurus and it was XM ready, so that is the route I took and honestly cannot say I have been upset or regret it one bit. Let me listen to Sirius for a bit and maybe I would find a reason to bash or hate on XM but as it stands right now I am happy with what I have
