Just stream me the weather, traffic, text msgs & some news stories that a TTS can read out to me.

SiriusXM is half way there. It supplies weather and traffic as a data service.

I knew about traffic from way back when the service was new, and found out Sirius Marine Weather a few years ago, but recently rented a car that also had Sirius-delivered weather and traffic alerts.

It was very useful as I was deeply off the grid (no radio stations at all during the day and AM skywave only at night), and the car alerted me to nearby lightning and thunderstorms that I couldn't see because of the terrain.
