Trafic Electrical Fault and Navigation Failure

Whoa, sounds like a proper headache! I had something similar happen with my Trafic. Electrical gremlins are the worst! Was anything done to the van recently? Like, did you change the battery or mess with any of the electrics before this started happening? It could be something simple that's throwing everything off.

No, I haven't done any electrical modifications or replaced the battery recently. The issue arose spontaneously. Could you elaborate on your experience? What were the symptoms, and what steps did you take to resolve the problem?

Right, so mine was a bit of a nightmare. Dash lit up like a Christmas tree, and the engine was acting weird. Turned out the ECU needed a proper reset. Honestly, with all those symptoms you're having, especially the navigation system going kaput, it's pointing to some serious software craziness. Best bet is to take it to a workshop with the right gear to reprogram the control unit. It's not something you can easily fix yourself unless you're a wizard with these things.

I appreciate your advice. Based on your recommendation and the complexity, I'll schedule an appointment with a qualified workshop to have the control unit reprogrammed. Thanks again for sharing your experience and providing valuable guidance.
