Marea electrical malfunction
Summary of the thread
A 2006 Fiat Marea is experiencing a general electrical malfunction, with the navigation system not working and an error indicating an implausible programming of the control unit. This issue is likely due to a glitch in the car's control unit software. The suggested solution is to visit a workshop for a software reset or reprogramming of the control unit, as it requires specialized knowledge and tools.

I haven't done any troubleshooting myself, as the 'implausible programming' diagnosis suggests it requires specialized software knowledge. I wanted to gather more information before going to a workshop. Did you have the same software malfunction diagnosed, and how was it resolved?

Yes, the diagnosis was similar. In my case, it was also a control unit issue leading to electrical problems. Given the complexity and the need for specific software, I would suggest you visit a workshop. They can perform a software reset or, if necessary, reprogram the control unit. It is like asking a doctor: He will check your blood before making a diagnosis.

I own a Marea as well, and your symptoms sound familiar. It's like your car's brain has a glitch. Have you tried any troubleshooting steps yourself, or directly consulted with a workshop?
