I have a 2018 c 220d the sat nav seems to have a mind of it’s own cannot trust it to direct me I just paid for and installed an updated SD card and still no different. Has anyone any idea what the problem could be?

Welcome aboard Dave,not sure but maybe the sat nav is not seeing the sats,I am sure a member will turn up with a answer.

I had bought a card for £39 on ebay but it was useless then I found one with map updates included it cost £99 but turned out to be excellent,
Not sure but maybe a badly written card.

The way I read the op's question was that a three year old car/sat nav was not working correctly,and so he bought a ebay card in the hope it would fix the sat nav,what we seem to have is a cars sat nav which has maybe been updated free for three years suddenly losing it's way.

The GPS antenna could be faulty.

There should be an option in the SatNav menu to check how many satellites it can see. It should see at least 4-5 (though the minimum is 3).

Always bear in mind a good percentage of stuff on ebay is pirate Chinese crap. Just a word to the wise.

I see no mention from the OP that he bought the card on Ebay or how much he paid for it. Am I missing a post or two ?

Thanks I checked that and it never has less than 12 satellites showing it is strange how when you make a turn it just looses its way.

I bought the card from MB

How long have you owned the car?

Yep no problem got that ok.

 

[mercmancdi]

Not clear or might have missed something,,,,, did you get the updated maps as sat nav was wonky when you got the car or was it kinda ok but you wanted to update the maps. Or was sd missing when you got the car.

 

[Dave109694]

How long have you owned the car?

8 months I didn’t use the sat nav for a long while as covid restricted movement so I don’t know how long it has been faulty and the car is just out of MB warranty.

I am assuming your car Audio20 with the optional Garmin Map Pilot navigation on SD-Card?

Try pulling the fuse that protects the infotainment system, to reset the navigation processor.

Other than that, I'm afraid you'll need to take to a car to a specialist who will also have STAR diagnostic equipment (preferably not a franchised dealer, to keep costs down).

The other option is to use Waze or Google Maps via Apple CarPlay / Android Auto. If your car is the facelift model, then it will have Audio20 5.5 and these features can be enabled, if it's pre-facelift then it will have Audio20 5*1, that requires additional hardware to support Apple CarPlay / Android Auto.

Thank you so much for the advice, do you happen to know where the fuse is. Although my car is a facelift model with the 10” screen it does not have apple CarPlay this is why I need the sat nav to work. Do you think disconnecting the battery would achieve the same thing?

 

[markjay]

You'll need to Google for a fuse layout diagram for your W205, unfortunately I don't have that info.

The facelift had Apple CarPlay / Android Auto as an option (on the pre-facelift there was no option for this), but you'll need to check if this option was actually fitted to your car from the factory.

Run the VIN in a free online VIN Decoder such as Free online Mercedes-Benz VIN Decoder : MBDecoder, it will show the full list of options that were ordered with the car, then look for these options:

16U Apple CarPlay
17U Android Auto

If your car does not have these options, then they can be retrretrofitted. You can talk to forum-sponsors www.comandonline.co.uk about this, though I appreciate they are not near you (you're in Manchester and they are based near M3 J3).

OP , If you got the card from MB they must have used the Reg/VIN to make sure they sold you the correct card ? Can we assume MB sold OP the correct card ...? or am I being a bit Daft there ?
