As already presented, we are often far from cell phone coverage so it is not a viable option.The best alternatives are some type of streaming service from your phone. You just might have to alter your data plan a bit to make sure you either get unlimited for whatever streaming service you use, or a high enough data plan that you won't go over all the time.
The only thing is it is the old way of satellite radio, with a separate controller for it, rather than controlled via the head unit. IT is clutter.I may be missing the obvious but wouldn't something like this work?SiriusXM Onyx Plus with Vehicle Kit - Shop - SiriusXM Radio
I think you end up with control not on the head unit but off in some other box, like in the original days of satellite radio, I had a huge box on a bracket . . annoying.
