I have the file for the 2.2 update for NAV. I am wondering if there is a file for the current 1.0 system, just in case I need to downgrade, or if the update bricks my system for some unlucky reason. Did someone post a 1.0 file earlier? I scanned through the 9 pages of posts but didn't see it.

I misunderstood the question. No, i don't think i've seen the file for the previous version.

Oh, and I saw this asked before somewhere, but never saw an answer... is there anywhere to download v. 1.0 of the sync 3 software? I would hate to try installing 2.2 without having a back up of the original system. I did a search for v1.0 online but didn't see it anywhere...

Someone posted some links to the updates earlier in this thread. The zip files contain two updates. Loaded the first update, then cleared the flash drive and copied the second update and loaded it. Carplay is working flawlessly so far.

Thank you all for the incredibly useful information. I was able to successfully install the GJ7Z-19A387-B that i ordered from Walt Sweney. Just wanted to add a tip to replacing the module. I had ordered the trim tools as well and struggled for a bit. i was able to remove the bottom portion, but could not get the top to release. then it dawned on me that the back side had the little shelf area, and is accessible from behind. Simply remove the side console trim, then pull back the trim behind the module. you can then press the release tab on top and it will pop right out. Attaching a few pictures.
