I was just reviewing my XM renewal compairing it to Sirius, one important differance is major city road reports, it comes standard on XM, $4 per month extra on Sirius. Those reports were very handy on my cross country last summer. This service made me stick with XM.
I will be selling an autocom easi7 with 12 adaptor and power plug for $85 shipped, it has been used about 10 hrs, I don't like all the wires coming out of my helmet, it just bothers me. I'm going with a set of small speaker and amp. The only thing with my easi7 is the passenger plug was clipped off to lessen the bulky extra wire.
sorry if this appears to be a hijacking, I just thought it would be a good place to make this reasonable offer.
