Aloha,
On a AVIC - X930BT
I am in a similar boat.
Ran shortfuse and installed 2017 USA Maps without a glitch. Just make sure you follow the directions.
Went to BlueTooth settings and updated to 3.32 from 3.22 without a hiccup.
1. AS Gooby389 inquired please point us in the direction of the STICKY for removing the NAG screen. I have Pioneer_T1000-25818 loaded on a card ready to go would I use a file in this repository to remove it ?
2. Also for BlueTooth how to from 3.32 to 4.6 to 6.0 and is it worth it to upgrade the version ?
3. Screen mirroring VIDEO from Iphone 6( running iOs11.2
