To improve my understanding of the phenomenon, it would be highly beneficial if you could share a full screenshot (Do not crop it). Visual representations carry a greater impact than written descriptions.

Please remember that this is a public forum, so when attaching a screenshot, please avoid including any personal credentials such as IP addresses, card details, email IDs, Apple IDs, IMEI numbers, serial numbers, phone numbers, order IDs, or any identifiable location information if you are sharing a map.

With the limited information that you have provided, It is hard to even guess the problems faced by you.

Please get in touch with the car delaer and ensure that your Ford Sync 4 system has the latest software update. Sometimes, compatibility issues arise when the car's software/firmware is outdated.

If the issue still persists, download the FordPass app from the App Store if you haven't already. Some features of Sync 4 might require this app for full functionality.
