After countless days trying to activate my navigation on my 2015 Explorer Limited, much help from the FORScan team (Thank you again for pointing me in the right direction), and numerous communications with a Youtuber, I have found a problem and solution. If you update your SYNC to version 3.10, as you know, you cannot reverse this. You also will lose your navigation (and I lost my 911 assist too). The patches to put it back all reference version 3.08. I have found a file from xda developers that repairs the navigation installation with SYNC version 3.10. I have followed all other steps (install navipatch, wallpaper, master reset, etc...), and then I found and installed this file. My navigation works. I love it. If you updated to 3.10, install your navipatch like normal (I think...you can experiment), reprogram your APIM with FORScan, master reset, install this file, and master reset again. You may not need to do this twice, I dunno. I only know it worked for me.

I updated to 3.10 version and I had no problems - I just had to re sync my I phone. And as the first post says, when you are complete, it says 3.7 done successfully. However, when you report the update to Ford and review your history, it does say it is 3.10 version. One thing I've noticed is that it seems if your Sync 2 was updated to 3.10 by Ford then those seem to cause this issue. One solution has been for many to go back to Sync 2 version 3.08 and enable navigation and then upgrade to Riochim's version of Sync 2 ver. 3.10 - IF YOU WANT TO. Not much difference from 3.08. Sync 2 MyFord Touch Navigation. I had trouble getting my sync 2 downgraded from 3.10 to 3.08 so I thought I would do a step by step outline to do. Pioneer Ford shows you how to use your Settings to Customize your car equipped with Sync with MyFord Touch.As always, feel free to call Pioneer Ford with any. The system reboots, and then an installation progress bar displays on the touch screen. This segment may take up to 20 minutes. You may see some variation in this segment, depending on your system. At the completion of this part of the process, a “Restarting System” message displays on the touch screen. A reboot will occur during this process.

Many, many thanks to FORScan, XDA developers, and the guy on Youtube that FORScan team pointed me to (sorry, I don't remember your name at the moment).
