Crown Victoria Electrical and Navigation Issues

My 2005 Ford Crown Victoria with a gasoline engine has a stored error, general electrical malfunction, and the navigation is dead. I think the control unit programming is bad. Any ideas?

Sounds like ECU problems. Any recent work done on the car before this started? Battery been disconnected or replaced?

No recent work or battery changes. Could a voltage spike corrupt the control module? Can I reset the ECU without special tools?

Voltage spike could do it, but unlikely without other issues. Resetting without tools is a gamble. The software bug theory is likely correct given the symptoms. Best bet is a shop visit.

Thanks. I have an appointment with a shop to fix it. It should cost around 240€. Thanks for the help.
