I'm posting this in case anyone has experienced a similar issue, and since I have a possible resolution that is working so far. During the past few months, in my 2017 Fusion SE 2.0L with 28k miles, various interior controls stopped working intermittently: climate control buttons, touch screen, seat memory, window switches, audio controls. Sometimes whichever control was out would came back right away after restarting the car, other times the problem would persist for up to a day. This would happen a few times a month no matter who was driving. The issue became more urgent when my wife couldn't turn on the defrost/air-conditioning during a rainy drive despite repeatedly stopping & starting the car. First part of trying to resolve was getting the battery checked at Batteries Plus; they determined the battery was only allowing 70% capacity charge and had sulfated due to too many short trips, so I replaced the battery (they offered to try and overcharge it back closer to original capacity, but I didn't want to make more trips back and forth and keep this as a troubleshooting variable). Problem came back a week later, again with my wife driving. Took it to dealer for warranty service, where they found numerous codes (non-check-engine-light worthy(?)) and "re-initialized" the car for the new battery but otherwise were unable to reproduce the problem(s); they got the codes cleared and could not make it produce new ones in a (likely short) test drive. Problem with CC/seat buttons came back as soon as my wife drove the car again. More troubleshooting at home, eliminated the position of the steering wheel as a factor, then determined it has something to do with wife's seat position (memory setting 2), which is up and forward for a 5'4" person instead of down and back for 6'1" person. Took the door apart and cleaned the connectors, but reproduced the CC button problem again afterwards, so it (probably) wasn't the memory switch or door wiring. Finally determined that lowering the seat an inch from position 2 would make the problem go away, so it was something with the wiring under the driver seat itself. Wiggle/bend/pull wires didn't make it occur, so (hopefully) no broken wires. Unplugged and re-plugged all the connectors (there are a lot) under the seat, and the problem is no longer reproducible with seat raised, and has not occurred for a week now despite various attempts and driving with the seat all over the place. Fingers crossed it was just an intermittently faulty pin connection to whatever module is mounted under the seat (although the battery issue might also have contributed, these newer models want a battery in "good" condition). I did find a link online describing similar issue, but no resolution given: http://www.carproblemzoo.com/ford/fusion/front-seat-power-adjust-problems.php

Its worth a try. FWIW, there is no official support for Windows phones, but Sync3 works pretty well with my Nokia 1020. Pandora doesn't autoload from the car menu, but if I start it on the phone it displays on the car screen and plays just fine. Text and phone commands and music via bt work fine too.

There is a USB input to the stereo, so possibly a USB to line adapter would work through the microphone plug-in. There are a number of them available.
