The SD slot in the console appears to take an extremely large card that I first used more than 20 years ago. Does anyone know the specs for the SD Memory card and any capacity limits? I couldn't find the information in the online user manual. My SA said "what's an SD Memory card?" He knows about cars and sells many, but knows very little about the embedded software.

my guess its a regular size SD, if not it would say mini or micro.

I have a 128GB SDXC UHS-I Sandisk card that I use in a camera. I'm wondering if it will work. I don't want to just shove it into a slot and watch it blow.

Regular size card

Should work fine. Since its for music files, Id buy the cheapest card with the largest capacity. You can buy a 256g card for less than 150 bucks which should store 100's of CD's without compression. If you use MP3s at highest quality you can have thousands of songs! In a car, the best rate MP3 bit rate is more than plenty good.

I use a 64GB SDXC card with no issue. It's loaded up with FLAC, AAC, MP3, MP4 files. The E300 plays them all - The lossless files sound pretty nice.

I agree with the others, a standard SD card will work...I'm using a USB powered 500GB portable hard drive which I keep in the center console.

Check the COMAND manual for data carrier (CD-R[W], DVD-R[W], SD, or USB) limits. There should be a section like the following (from the X253 COMAND manual):
I'm away from home and can't check the COMAND manual for my wife's E300, and I couldn't find a PDF online.

I'm guessing they stayed with a standard SD card as micros are ridiculously small & easily lost. Most micro cards come with an adaptor that makes them standard.


I think any format & any size card is fine (in later models that is).

Good to hear your car plays flac files. Mine does not. It lists in the manual it does not support flac. I wonder how yours can?

An annoying quirk with media (SD or USB). I initially used MP3s that had (scrambled) tags mostly reversed artist song or album. I used a tag editor to correct these tags but they will just not update when the source is reused. Instead the system insists on reading the cached data!
Does anyone know how to clear the cache, I've swapped cards, drives, added files - nothing works!


Okay I figured it out!!!

Because most MP3 tags either have no Album information of if they do it's incorrect I decided to delete this tag by delete! The album tag is the third line on the display, the fix was not to delete but use a line of spaces on each track. This then deleted the cached data & gets rid of it! Maybe this will help someone else who is pedantic or nit-picking as I am!

In the user manual, only these formats were listed, and it does not include FLAC.
MP3
WMA
AAC formats

Does W213 really support FLAC?

I think the problem has to do with it contacting GraceNote Servers to get music info from your card. If it gets a (wrong) hit there is nothing you can do about it. No editing the tag helps. I've tried doing this as well. I've even contacted them to ask this same question. The media player is engineered wrong. It should be... Read tags first contact server second.

About playing flac... Some w213's can, some can't. It goes by VIN number. Don't shoot the messenger. My car can't (has upgraded audio in it - is that the Performance Package?), my current W213 loaner can (is a basic package car, no upgrades.). Don't shoot the messenger, just exposing Mercedes practices.
