Has anyone else noticed just how terrible XM sounds when compared to Sirius. I have both Tuner's added to my F90bt. I couldn't believe just how horrible and compressed XM sound's. The only reason I added the XM tuner is I wanted the song and artist title on the display at the same time. DEI makes the Sirius tuner. And anyone familiar with DEI would probably agree they should have never left the car alarm market. So I purchased the Pioneer GEX 920 XM tuner with no worries. I was so let down with it's performance. It sounds like total garbage, only 7 channels actually have there own station logo
