Not sure about the RDS, but it definately messes up the Sirius. You can no longer change presets on the tomtom screen. They are aware of the problem but haven't released a fix yet. I downgraded to v6 again. I can't even get TomTom Home to show the v7 software anymore. I think they pulled it.
I read that there maybe some issues with the RDS and Sirius on the version 7 update. Is this true? I have the update sitting here and new mpas too but dont want to take the plunge until I understand what is broken in this update. I have the AV2210p, with 6.554 still...
