I just installed 2.6.0 on my 2025 Touring with non-pro Surreal Sound.
1. I have a Samsung Galaxy S24 phone, and when I got in my car this morning, my phone said, "You are connected to Android Auto." Obviously, LUCID added some of the software necessary for Android Auto in the update. They are just waiting for Google's final approval.
2. I am not an Audiophile, but the sound of my non-pro Surreal Sound also sounds better now. The volume control is more linear, and it sounds like all the channels are coming out of the correct speakers now. I have not heard how this update was supposed to affect non-pro Surreal Sound, so I am unsure if my observations are real or an illusion.
