Recently when I turn the car on the audio system goes to the source page. The sound system goes to the last one that I used, typically Sirus XM. In order to go to the serous screen I need to touch the serous button. For several years it did not operate this way, it would go directly to the Sirius screen. I don't know if a setting accidentally got changed or why this is occurring now. It is not a big deal but it is annoying. I have tried rebooting the system and have looked for a setting that might be causing this but neither has any effect.
