I am facing the same issue. In the Mercedes Benz store, the navigation shows as not compatible with my 2024 GLC 300 4matic, but under the system information, there is an option to view map data.

I found the hidden dealer menu and upon entering, navigation is listed as deactivated, so I know the car supports it.

I did notice that the Mercedes Benz store under navigation, there was supposed to be a software update in Sept of 2024 for it to be available, but in the hidden dealer menu, mine shows the last navigation update of Jun 2024.

Not sure if that is the issue, but something I have found so far.

 

Where did you find the hidden dealer menu?

 

Thanks for your reply. I have gotten as far as you have, actually a little further, but no resolve. I contacted the dealership and the head of the Service department had me bring my vehicle in so they could update the software. (I purchased a Certified Pre-Certified vehicle with low miles.). They did the software update and it took a few hours but the said it was doing everything it was supposed to do, but it was ultimately unsuccessful. I don't think software is the issue. The head of service is still trying very hard to help me and he said he has been in touch with a MB engineer and they want me to bring my vehicle so they can connect it to "Live Case", and take a look at the codes. I am assuming this is someone at the headquarters in the Atlanta area. I will report back on this forum once the engineer has a report for me. Fingers crossed that this can be resolved and I am happy to share my experience in hope that it will help you too. What a frustrating mystery!

 

My dealership (Mercedes-Benz of Easton) in Columbus, OH was successful at getting navigation working in my GLC 300 4matic. They mentioned having to reflash the computer which took 5-6 hours and then the car showed as compatible. Navigation is now working successfully and currently downloading the map data for the regions I specified.

 

I would like to activate navigation in my 2024 GLC300, but dont know how to access the “hidden” menu. Can anyone share the steps to access the menu?

Thanks in advance!

 

You should not have to access a hidden menu. You should be able to purchase this on your MB phone app. Go to the upper left corner and click on the image of a car, then go to Digital Extras and click on Navigation to add it and follow the steps. If you are unable to access this, I recommend contacting your dealer.

 

What version is your car - Basic, Exclusive or Pinnacle? It makes a difference.

 

Clearly I’m not all that bright as I’m unable to determine the version after careful review of the window sticker and a VIN look up across several sites. Based on that, I’m going to assume that mine is Basic, so that is most likely the issue with my ability to have navigation added. Buyer beware, I didn’t do my due diligence when purchasing. Love the vehicle though!

 

I have no idea what Basic, Exclusive, or Pinnacle is either. Never heard of that. Call your sales person.

 

Your welcome. That's a great coincidence that you are also in OC. You can call him if that's easier for you..Ask for Matt Moskal and tell him I told you he is an expert in problem solving now and that I suggested you contact him. He's a really nice guy and if he can't get this done for you I doubt anyone else can. Let us know how things turn out for you.
