IPhone 6, iOS 8.0.2, constant dropped Bluetooth... a solution

Question

After reading many, many, many postings here on Apple Support and all over the web about the iPhone 6 and iOS 8.0.2 and how Bluetooth connections in the car are being dropped all the time for all different makes and models of cars, I figured I'd post my "adventure" and how I solved the problem.  This was posted as a reply to another posting, but I figured I'd start a new thread so people can find it easier.
Here's the posting and solution:
I had the same exact problem with my iPhone 6, running iOS 8.0.2, when connecting to my 2014 Ford Fusion with the My Ford Touch (MFT) system.  Calls would "drop" after about 10 to 15 seconds.  Only it wasn't the call that was dropping, but rather the Bluetooth connection crapping out. 
I found the answer (which I will list at the bottom of this posting), but first here are the many things I tried BEFORE I found out the answer:
1) updated 2014 Ford Fusion MyFordTouch with latest firmware upgrade from Ford (v.3.7).
2) Unpaired and deleted iPhone 6 from MyFordTouch
3) Deleted SYNC from Bluetooth in iPhone 6
4) Reset Network Settings in iPhone 6
5) Did Master Reset to MyFordTouch system.
6) Added iPhone 6 back into MyFordTouch
7) Successfully paired iPhone 6 with MyFordTouch
8) STILL dropped calls after ALL that.
The answer I arrived at after chatting online with Apple Support Reresentative ("Emmy").   I backed up my iPhone 6 to iTunes (even though I don't normally like to use iTunes), then used iTunes to do a RESTORE to my iPhone 6., which effectively downloaded a virgin copy of iOS 8.02 to my computer and then iTunes applied it to my phone.  This RESTORE function completely WIPED my phone clean (so I had to make sure I did a backup otherwise I'd have lost everything).
AFTER the restore of iOS 8.0.2, the iPhone started to walk through the setup.  BUT here is the IMPORTANT part.  THIS TIME, I said, "Set Up as NEW Phone" instead of "restore from iCloud backup" (like I had been doing).  I skipped the signing in with my Apple ID and all the rest and got to the Home screen.
Then I went out to the Ford Fusion and paired the iPhone 6 to the car.
This time NO dropped calls at all.  Worked perfectly. I spoke with a friend for over 5 minutes and the call sounded great.
THEN, Emmy (support rep) said to do an "Erase All Content and Settings" and to do it OFFLINE (meaning NOT to connect to iTunes).  So, iPhone 6 was wiped again.  This time when it came up, I *DID* do a "Restore from iCloud Backup" and restored the phone.
After the restore, I shut the phone off.  Went to car.  Deleted the pairing from previously on the My Ford Touch system.   Then took key out, opened door, and closed it (thereby "rebooting" My Ford Touch).    THEN I powered up my iPhone 6.
Paired to Ford.  Pair to iPhone.
And.... it WORKED.  And continues to work.
So... I'm not exactly sure why this worked.  The only thing I can figure is perhaps the iTunes RESTORE that I did, wiped everything and left a clean iOS 8.0.2 and then when I did the restore from iCloud it laid on only what was not already on the iPhone in a newer state.
After you read all the above, and after I typed this, I realize that this is a LOT to do just to get back Bluetooth functionality.
I'm thinking that Apple should release an 8.0.3 or an 8.1 update that will address all this for people that don't have over 3 hours to do what I did above to restore functionality.
I've seen other posts and this is happening to ALL car makes and models, not just Ford.
Hope this helped some people.

Even easier than what I wrote originally.    Just do a RESET ALL SETTINGS .  I was originally only trying the "reset network settings" but didn't try reset ALL settings.   This has helped 5 of my friends regain their Bluetooth connectivity with a variety of autos.   But remember two things: 1) back up data on your phone before trying this and 2) don't forget to delete the bluetooth original pairing from your car.
