BMW 6 GPS Navigation Problems, Dead Antenna Issue?

Hey there! I faced something really similar with my 2014 BMW 5 diesel last year. I've got some experience working on cars, but navigation systems aren't my forte. My symptoms were exactly like yours, super slow navigation and GPS signal drops. Took it to my regular workshop, and they found a faulty GPS antenna. The fix was straightforward, they replaced the antenna, and everything's been working perfectly since. Total bill was around 200 Euro. Just to help better, what error code are you getting? Also, have you noticed if the issues get worse in certain weather conditions? Hope you get this sorted soon! If you need any other details about my experience with the BMW 5 or 7 series, just let me know.

Thanks for sharing your experience! My car has 138074 KM on the clock, and the symptoms match what you described perfectly. The error code is 65892, and I've noticed it gets particularly bad during cloudy weather. Did your mechanic mention anything about checking the wiring harness before replacing the antenna? Trying to get an idea of what to expect when I take it in for service. The navigation was fine during my last service about 3000 KM ago, but it's been getting progressively worse. Just want to make sure I'm not missing anything obvious before heading to the workshop.

Hey again! Yeah, I totally remember when my BMW 5 had these issues. Mine had about 145000 KM when the problems started, so pretty similar to yours. And yes, that weather connection you mentioned rings a bell! My navigation would go crazy during overcast days too. Actually, funny you asked about the wiring harness, my mechanic did check it first. They found some slight corrosion on the connections, but cleaning them didn't solve the problem. They also ran a full diagnostic test before replacing the antenna just to be sure. Since you mentioned it was fine 3000 KM ago and got worse gradually, it sounds exactly like my situation. Mine also deteriorated over time, started with occasional glitches and ended up barely working at all. The error code you're getting (65892) is different from what I had (mine was 65890), but they're in the same family of GPS-related issues according to my mechanic. The antenna replacement sorted everything out perfectly, and I haven't had a single problem in the past year. Just make sure your workshop does a full system check before replacing parts. Sometimes these symptoms can be misleading, but in our cases, it seems pretty straightforward. Let me know how it goes when you get it checked out!

Thanks so much for all the detailed info! Really helpful to hear about your experience, especially since our cars are so similar. It's actually quite reassuring that your situation was so close to mine, same gradual decline and weather-related issues. That's interesting about the error codes being related. I'll definitely make sure to mention to my mechanic about checking the wiring harness and connections first. No point replacing the antenna if there's corrosion causing the problem, right? I've booked it in for next week, and I'll make sure they do that full system check you mentioned. Think I'm feeling a lot more confident now about what to expect. Hopefully it'll be as straightforward as your repair was! Really appreciate you taking the time to share all this info. Would it be okay if I let you know how it turns out after the workshop looks at it?
