Update. My radio is working now. Huge thumbs up for Tesla and my local service center!
I sent a text last night through the Tesla app about my service appointment this Saturday, asking if they could re-send the latest update. I was already on 48.30 but figured maybe it was a glitchy install. I was sent the update this morning, installed 48.30 again...but no fix. Texted that it still wasn’t working. They replied back saying its a known firmware issue, is supposed to be resolved in the next firmware 48.35 but that they would try to fix it temporarily remotely. Got a call 10 min later saying they fixed it remotely but that a permanent fix will be in the next firmware update. I went out to the car and it’s working. I noticed I was also missing the “stations” tab. When it wasn’t working it only showed favorites and direct tune.
