I get load errors when playing from USB and have done for years, so that issue isn't specific to streaming.
I have gotten those load errors from USB as well - and was able in one case to determine that one track seemed to be the problem. Even though it played fine elsewhere. So out of an abundance of caution, I acquired the same track from a different source, copied it to the USB and at least that load error did not recur.
However, there have been others. So now I travel with multiple USB sticks dedicated for music only and at some point will get around to acquiring a decent large-enough drive to consolidate the collection of sticks and ideally that will be that. Except then I suppose it would be good to have 2-3 of those larger drives in that case (working, spare and reference).
Streaming, or steaming, as it may more aptly be called lately, seems to choke at random intervals now. Which is to say always at least once during a road trip (no signal is what I'd like to think always causes it, but...) and now more as well in the local areas for no particularly evident reason.
Realized I've pretty much written off streaming audio management along with the lack of browser functionality and a few other things that hopefully will be addressed by the 6th or 7th iteration of whatever the "light years ahead" Nav release will be, and, tangentially, maybe by some of the interior refresh updates referenced by other senior management earlier this year. I distinctly recall references to an in-car hotspot *and* dashcam functionality, so, same church, different pew perhaps.
