BMW 1 Series Nav Dead, Transport Mode Causing Issues?

Hey there! I can relate, had a similar issue with my 2012 BMW 3 Series (coming from a 5 Series before). I have some experience working with cars, mainly basic maintenance and troubleshooting. Since your issue sounds really similar to what I faced, I'd suggest getting it checked at the dealership. In my case, it turned out to be a software-related problem that they fixed under warranty since the car was still new. It was a quick fix, they just needed to deactivate the transport mode and do a system reset. Before I can give more specific advice, could you share: How long has this been happening? Are there any other warning lights on? Did this start after any recent work or battery disconnection?

Thanks for the input! Mine's been regularly serviced (last one at 41200 KM), and these issues just started showing up last week. No other warning lights, but I've noticed the battery seems a bit weak during cold starts. Haven't had any recent work done besides routine maintenance. I heard disconnecting the battery for a few minutes might help reset things, but I'm a bit hesitant to try without getting some expert opinions first. Has anyone tried this fix specifically for navigation/electrical issues?

Hey again! Looking at your latest update about the battery, this actually rings some major bells for me. My 3 Series had very similar symptoms, weak cold starts were definitely one of the first signs before the electrical gremlins started showing up. In my experience, while disconnecting the battery can sometimes help, it's really just a temporary fix if there's an underlying issue. I actually tried that trick myself before going to the dealer, it worked for about two days, then all the problems came right back. Given what you're describing, especially with the weak cold starts, I'm pretty confident you're dealing with a battery that's on its way out. These BMWs are pretty sensitive to battery health, when the voltage starts dropping, they throw all sorts of weird electrical issues, including nav system failures. My advice would be to get the battery tested first. When I finally got mine checked, it was operating at about 70% capacity, which was enough to cause all those symptoms. Got a new battery installed, and like magic, all the electrical issues disappeared. Just make sure if you do replace the battery, get it properly registered to the car's computer system. I learned that one the hard way, these BMW batteries need to be "introduced" to the car's systems to work properly. Trust me, it's worth getting this done right the first time!

Thanks so much for all this detailed information! This definitely makes me feel better about the whole situation. You've pretty much convinced me that the battery is the likely culprit, especially since the symptoms match up so closely with what you experienced. I'll skip the battery disconnect attempt and just go straight for a proper battery test. Didn't know about the battery registration requirement, that's super helpful info! Will make sure to have that done properly when I get the new battery. Really appreciate you taking the time to share your experience. It's saved me from potentially wasting time with temporary fixes. I'll get this sorted at a proper shop and hopefully be back to normal soon. Thanks again for all your help!
