I have a 2017, F250 and the voice commands on navigation will get garbled up and then become to low to hear and can not be turned up to a level to hear or understand. Ford dealership has had vehicle numerous times and replaced the module 4 times as well as the center speaker. The code says to replace module every time. Now it is giving a code that doesn't exist they tell me. The radio had be resynced and rebooted several times. Anyone had a similar issue and how was it resolved?
