I've only had one dropout since I upgraded from 70.00.100 NA N to 352. Easy enough to do the upgrade yourself. I kept having regular multiple dropouts before upgrading. I had let my trial expire because I was tired of said dropouts. I only renewed it cause they lured me back with 12 months for $60.New version out: 352
According to J32 a new firmware version corrects the Sirius issue. Don't know if dealers have the the new version.
