SD Card SatNav Replacement

Hey guys,

Recently acquired C200 AMG 2021 model with SD missing.
Can you recommend correct SD and where to get this please?
I've searched for compatible SD online to no avail and local MB garage is asking for over £650 for replacement which I don't have.

Thank you.

The SD card is for Garmin map pilot, which is much more basic than the MBUX hard drive navigation. Each SD card becomes locked to the head unit after it's inserted, so people only sell new ones.

The size of your center screen will determine which NTG version SD card you need. If it is the larger w205 screen (not standard in some markets on newer models) you need an NTG 5.5 card. If it is the smaller screen, you need an NTG 5 card.


NTG 5


NTG 5.5

Since you have a 2021 AMG, you likely have NTG5.5. Unfortunately, these cards are much harder to come by than NTG 5. Search online for "NTG 5.5 navigation card + your region." You may find many results priced at $100, but be careful, many listing say UPGRADE and will not add maps if they are missing in the first place.
