@RangerBill is referring to the Sync3 reindex process. You can reindex the iPod to Sync3 by going to media settings, then select reindex, unplug the iPod, then plug it back in and it will run the indexing process.
Also, have you tried voice commands? If there is an indexing issue, it may...
EDITEDā¦
When using the iPod menu, Iām guessing it is locking you out since itās connected to Sync3. Try using the Browse function from the Sync Audio screen. You may also be able to use voice commands to switch artists, find a specific track, shuffle all songs, etc.
Does this happen on both USB ports? If so, I would try to let the hardware reset by either pulling the appropriate fuses or disconnecting the battery for a short time. If you do disconnect the battery, youāll need to reset the auto down/up on the driver door window.
What version maps do you have? I know you said you are up to date. The latest maps are NA 2 25 which just came out about a month ago. No guarantee it will have what you want though.
If you donāt get anywhere with Grainger, give Zeigler Ford a try. I bought 2 warranties from them, all online with no issues. At the time, if you paid in full, they were giving an extra $250 discount. Just had to use āPAYINFULLā as a code during checkout.

Make sure you are on the latest version 3.4.23188. Anything older has built-in issues that develop over time.
And if all the fuses and wiring are good, you might try pulling the fuses (or disconnecting the battery) for a short time to let all the hardware completely reset.
What type of mp3 player and are you on Sync 3.4.23188? If on an earlier version of Sync, I would update to 23188 as it resolved a lot of issues with older versions.
If you are current on Sync and if it worked before and now suddenly doesnāt, assuming you made no changes to the settings/setup...
Some 2023 Explorers are part of yet another Ford recall, this one for a stalling issue. Maybe this is what you experienced, maybe notā¦. Worth checking out.
Guessing it would need to be programmed.
But before replacing it, have you tried pulling the Telematics fuse or disconnecting the battery to reset the hardware?
EDIT: The Telematics fuse is #9 in the Passenger Compartment Fuse Box.
I have the Topdon BT100. My battery was testing poorly (only a year old), recommending replacement. I was not having any issues, just the bad test reults.
I was about to return it for a warranty replacement and I actually removed the battery to take it back. I decided to test it disconnected...
