Problems with the navigation system in the Citroen Jumper Diesel 2016: looking for solutions and advice

Hey, I had a similar problem with my 2014 Citroen Berlingo. I can't really claim to be a car professional, I don't have much experience, but I'll do my best to help you. In my case, it was the CAN-BUS or MOST bus that was damaged. They replaced the part in the workshop and got everything working again. It cost me about 235 euros. To help you more precisely, could you provide some more information about your vehicle? Or have you perhaps already been able to rule out some sources of error yourself?

Hey, thanks for the tip. Sounds like a possible cause. Mine is now at 164774 KM on it. I went through the last service 2 months ago, so it shouldn't be a problem with general maintenance. I haven't actually made any modifications to the electronics. Your repair sounds like a possible solution. Thanks for sharing your experience!

Hey, no problem, I'm glad if I can help. Maintenance isn't always the answer to everything, sometimes problems occur that you can't predict, especially with systems as complex as navigation systems. Like mine, many factors could be responsible for the failure, including age of the vehicle, mileage, weather conditions and many more. In my case, the garage read the fault memory and found the broken CAN-BUS/MOST bus. As I said, this was a costly affair. But if it solves the problem and gets you back on the road, it's worth every penny. Maybe it's the same problem with you. I hope this helps you and gets you closer to a solution. Good luck with the Jumper, buddy!

Hey, thank you very much for the detailed answer! It helped me a lot and I really appreciate you sharing your experience and knowledge with me. Yes, you are right. With such complex systems like navigation devices, there can be a whole range of factors that can lead to problems. Your words have helped me to see the problem from a broader perspective. I think I'll take it to a garage and point out to them what you've said. Hopefully they will be able to solve the problem. Thanks again for the help mate!
