c300 2016 Pre wiring nav meaning?

Hello,

Trying to see if anyone can help me, just previously bought my c300 2016 and when i bought it, it stated that it was pre wiring navigation does that mean all i need to do is insert the navigation sd card ? When I press on the navigation button on my card it states insert sd card.... If anyone has some answer I would appreciate it.


Thanks,
Lidia Benzo

Sure... "pre-wired" means there is a SD Card slot in the console that will fit a Garmin Nav Card.

You can buy the Nav Card here: https://www.ebay.com/itm/2015-2017-M...0AAOSwbF1bkR6m

As farbbrisd1 stated, pre-wiring means that your car has all the hardware (and software) needed for the Nav system but it still needs the Nav data to come from a valid Nav SD card. When your car has the Nav pre-wiring option, you can look up the car's VIN decode and it will have the Audio 20 prewiring codes (522 + 355 in your case I think) in the VIN decode.

From what I researched any C-Class built before 08/2017 requires A2139069903 (looks to be the same as the ebay item that farbbrisd1 shared). You should be able to find deals for at or less than $60 from a reputable seller if you search a bit. Since there are few different models and variants of SD cards and the compatibility varies, it is good to check with the seller on Ebay w.r.t. compatibility by sharing your VIN number before the purchase.

There have been few sellers who sell fakes which fail at the time of activation. A given Nav SD card gets paired with the head unit at the time of activation, and cannot be used on another car after that. Each SD card has a unique CID (Card ID) as well which is part of this signature and pairing/activation.

Some good info about various Nav/Multimedia options and their codes listed here.

Actually - V8.1 for about $60 from a "reputable" eBay seller is smart-enough deal. I have bought maybe 15 cards from same seller - and they have always been straightforward - and the reason I recommended them.

I agree, there are lot of fakes. $75 is not a bad deal, if the seller is reputable.

I bought my SD Card (MB Entry SD card nav which is different from Garmin Pro Pilot) that was compatible with the MY2019 widescreen C-Class from a different seller for $60. I found the seller to be quite reputable based on reviews (5000+ overall ratings and no negative rating over the last one year). https://www.ebay.com/usr/newbdeals However, it looks like this seller is not selling any SD cards currently that work with pre-2018 cars. All of this seller's items are under $65 or so I believe when I checked last time.

C300 NAVIGATION

Hoping you can help.
I just purchased a 2019 C300. The console does have a slot for Nav. but the card was missing. I have purchased a few cards that were not the correct cards but I believe I have the correct card now. I have researches lots of sites on how to load the card and work the Nav nd I cant get it to work.
Do you or anyone have experience on how to get this working...its been very frustrating.

Thank you

If you have Nav Pre-Wiring - when buying a Ebay Nav Card ALWAYS message the Seller with your VIN# so the Vendor can confirm the right MB Part# for your MB.

Scott - sorry you can't add Nav Card if you don't have Nav Pre-Wiring - you have CarPlay/Android-Auto right ?

Greatly appreciate the response. Yes I do have car play. Can Nav Pre Wire be added if you have
-gps antenna-sd card slot-506 Nav capable radio. So strange all those parts exist except for what probably amounts to a harness wire.

I have an SD card slot. I do not have the prewiring. It just means that if I have the built in nav, I can manually download the maps from MB. Actually I think I can use it to play music also. I haven’t tried that.
