Iphone 15 will no longer sync.

[reinman68]

I have a 2021 Badlands. My phone used to sync as soon as I got in my Bronco, no problem. About two weeks ago it stopped connecting, I can't even manually connect it. The only thing that worked was deleting it from the dash and then reconnecting it. But that only works until the next time I drive my Bronco. Any ideas?

I would consider that a blessing! However, the update to your phone or Sync is not in rythm.

Can you let us know some more information?

It’s like you never upgraded the Sync software from the factory installed version

For ‘21-‘24, this is latest Sync:

SYNC 3.4 23188 (available Sept 2023)
