I don't have the official dock, but I do have the Jsaux dock. Maybe I'm lucky but I haven't had any of these issues, the worst I had was audio came out of the Deck rather than TV after I put the deck to sleep, docked, then woke it. But a quick setting change and back to normal.
It gets the number that's ringing and compares it to a database it downloaded. It's not doing anything with your sensitive data.

I find it easier. It's also safer, backing out of a space you're more likely to hit someone walking or driving past. If you find reversing in to a space hard then maybe you shouldn't be driving a giant metal death machine.
Big fan of Mighty Car Mods. Been going since the mid 2000s, but still don't do any BS, just good car videos. From long Top Gear Special style videos like Kei to the City down to quick and small videos like How to change your steering wheel.
