Problems with navigation system and audio in BMW 3 Series 2007 - looking for solutions and experiences

Hey guys, I have a problem with my 2007 BMW 3 Series - gasoline engine. Somehow my navigation system and the audio system are completely out of order. I already suspected that it could be the MOST bus (I did a ring break diagnosis and so on). Have any of you experienced something similar and can give me a few tips? I would be particularly interested to know how this was solved in your workshop and what your experiences were. Thanks in advance!

Hello, I can well understand the annoyance, I had a similar problem with my 2005 BMW 5 Series. Now I'm not a professional, I only have average experience with cars, but my visit to the garage helped quite a bit. It turned out that the plugs on the control units were broken. The repair cost me 152 euros and since then everything has been working perfectly again. So it could be that you have the same problem. But can you give a little more detail about your vehicle, such as the specific model and mileage? Maybe then I can help you more precisely.

Hi, thanks for the helpful tip. My BMW is a 3 Series model and the mileage is 198412 km. The last time I went to the garage for an inspection was 2 months ago, but everything was still okay then. I'll keep your experience in mind and take it to the garage. Maybe it really is the plugs. Thank you!

Hello again! With such a high mileage, it can happen that one or the other electronic system goes haywire. In your model, the MOST bus is responsible for communication between the multimedia-related control units. So if the navigation and audio systems fail, this is an indication of this. You also wrote that you carried out a ring breakage diagnosis. Did you discover a defective component? In my workshop, they checked this with a special tester and found the fault. But it could also be a simple thing like a loose plug, as I have already experienced. In any case, I would recommend having it checked at the garage. But I'm really glad that my tip has helped you. I hope the problem is solved quickly - good luck!

Hello, thanks again for the quick reply. As you suspected, I was unable to discover a defective component during the ring breakage diagnosis. It would be really nice if the problem was just a loose connector. Your tip gave me an interesting insight into possible causes, which I will definitely keep in mind during my workshop visit. Nice to know I'm not alone with a problem like this. I'll get back to you when everything is OK. See you then and thank you!
