First, my apologies....
I recently bought a c300 4Matic from Carvana. Using mbdecoder and doing a little research I have listed codes 506 & 355 as included options. Build date 6/2018.
As many have no doubtedly asked, I'm in search of a way to activate my navigation. I have the big red navigation icon on the main screen, NAV1 as a toggle and also
Navigation in the driver info screen. However, when I access it says I need an SD card. There is none in the slot.
I can go to the dealer near me and ask but I thought I'd get the skinny here first.
I've looked all over Ebay and Amazon but can''t seem to find one compatible.
Carvana has been of little assistance BTW, any insight would be great!
Thanks to all that take the time to respond, I appreciate it!

I think this one on Amazon is compatible. Seems like a handful of options, but this was the cheapest I saw. For the price, buy, try out, if it doesn’t work, free return.
