This may be due to an incomplete installation of the SYNC map software. If possible, using the original USB that installed the update, reperform the update and verify the navigation voice prompts have returned. Multiple reboots are expected when this update is being performed. Verify the Installation Is Complete message displays in the touch screen. If the original USB is not available, go to website https://syncnavigation.com/ford/home or https://syncnavigation.com/lincoln/home to download the files once more for the affected vehicle. For further map update support, reference the FAQ section on these websites.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10205694-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10205694-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10205694","components":[{"id":"electrical","name":"Electrical
