So, I have a 2017 Explorer, LTD, fully optioned. I also have an unlocked iPhone 7Plus, iPod nano and iPod Classic. 70% of the time they work fine with Sync. 30% of the time they will not be recognized, I will not get voice recognition, my screens will not recognize any other media beside Am, Fm, or Sirius. I've taken my Explorer to 3 different dealers. In two of the cases the service advisor sat in the vehicle and observed the issues cited above. In all three I provided videos of the symptoms as they occurred. Once dropping off the vehicles, the technicians have not subsequently been able to obtain an error code. I've been told that unless they do there is nothing that can be done. Ditto with on-line contact. Now I'm told that my iPhone 7 Plus is not compatible with Sync (Unlocked, Model MN4E2LL/A, with a Straight Talk Sim, Carrier Code TFW.290). Apparently, Sync does not abide with unlocked phones or the sim cards that it might use. It's funny that the MyFordTouch in my 2012 (traded in late last year) was just fine with every device. So, Fords online assistance and the dealers tell me that my word, the video's demonstration and the service advisor's written service order mean nothing if the technician can not generate an error code. 'Take your car and shove it.' Sorry, that's the way it goes. 8600 miles with a Sync system that, intermittently does not recognize previously recognized media in the same vehicle, that doesn't sync some of the phone contacts, that sometimes doesn't respond to voice commands. No wonder they launched the Challenger: Sometimes the launch temperatures were above freezing. I guess that explosion didn't happen. In so many ways, this 'new' explorer really stinks. But, if the technicians can't smell it, it don't. Any solutions or recommendations would be appreciated (just not 'try another dealership' or 'live with it'. Thanks.
