I have theory about drop-outs on SiriusXM and other streaming services. I'm starting to wonder if it has to do with the wifi to cellular handoff. I have strong wifi in the garage which lasts until a couple hundred feet outside my driveway. Streaming services work great the moment I get into the car. Then, when it needs to switch over to cellular, there is often a lengthy period (30 seconds) of silence as the system figures it out. Then, it's fine again. As a possible solution, I turned off wifi within the car itself and the problem seems to have gone away. I will continue to monitor this. Meanwhile, I hope a future update makes this handoff more seamless, like on a phone.
