I have a relative who is an engineer with Sirius/XM. He got me started listening to Sirius about 10 years ago and I'd hate to be without it.
Got my wife a newer vehicle a year or so ago and it has XM and we too experienced signal issues - something I've never really had with my XM. I asked said relative about it and he said reception issues are common with XM, especially when traveling East/West or the reverse. Something to do with the location of the XM satellite. The Sirius satellite is apparently in a location in orbit that results in very few reception issues. Whodathunk that they'd still use 2 different signals and satellites so many years after the merger.
My recommendation is to ditch the in-dash XM receiver and get an add-on portable under the Sirius plan.
