Navigation system problems and possible audio system restrictions in the 2017 Mercedes GLA Class

Hi, I had a similar problem with my 2015 Mercedes GLA class, so only two years older than yours. My car knowledge is somewhat limited, I would say I have a low level of experience. At my garage they found out that the cable connection between the control unit and the display was faulty. They said it was a bad connection. Had to replace the cable connection, the whole thing cost me 165 euros. But to be able to help you better, I would need a bit more information about your car. Have you noticed if the sat nav system suddenly cuts out or are there any other symptoms? Any information could be useful.

Hello and thank you for your feedback. The garage checked everything on my GLA during the last service (at 91336 km) and there were no abnormalities. It's just that the sat nav sometimes fails, sometimes while I'm driving. There are no other particular symptoms, it just doesn't always work. I then have to restart the car and then it works again. Totally strange. What do you think?

Hi, thanks for the additional information. It's definitely an unusual problem you're having. I can imagine how annoying it must be when the sat nav just cuts out all of a sudden. I had a similar situation when my sat nav would occasionally just cut out. The solution in my case was a software update. The garage updated the car's operating system and since then I have had no further problems with my sat nav. I would therefore advise you to first check whether your software is up to date. If that doesn't work, it could of course be that it's actually a hardware problem, such as a faulty cable or a broken connection. In this case, you should definitely take your car to a garage at the next opportunity so that the experts can take a look at it. Hopefully they can solve the problem quickly and inexpensively. Good luck and let us know what it was!

Hi, thanks for the tip. I hadn't actually thought that it might be a software problem. I'll call the garage tomorrow and see if they can do an update. If that doesn't help, I'll have to have the cable checked. I hope it's nothing too expensive. I'll definitely keep you posted on what comes of it. Thanks again!
