Hi All,

I am new MB, CLA user. After reading your posts I have searched around and found this interesting solution on some other forums:

Just sharing some information about my 5F0.919.866.C SD card with everyone. I can reading the CID using (cat /sys/block/mmcblk0/device/cid), and I get:

09 4150 4D49425354 10 73C41437 0 0CC 00

Breaking down the fields I have:

Manufacturer ID: 09 h (assigned by SD card association)
OEM/Application ID: 4150 h (Assigned by the SD-3C LLC)
Product Name: 4D49425354 h
Product Revision: 10 h
Product Serial Number: 73C41437h
Manufacturing Date: 0CC h

Date: 12/2012
Name: MIBST

USing (cat /sys/block/mmcblk0/size), it returns 16152576

So Size of my card = 16152576 x 512 = 8270118912 bytes

Using Gparted, I can confirm it reads the following info:

Cylinders 1005 Heads 255 Sectors/track 63

Total sectors: 16152576
Sector size: 512

Existing partitions:

File System: unallocated
Size: 4.00 MiB
First sector: 0
Last sector: 8191
Total sectors: 8192

Files System: fat32
Size: 7.70GiB
First sector: 8192
Last sector: 16152575
Total sectors: 16144385


As I mentioned earlier this appears to be a special SD card in that it actually holds more than the usual 8GB. If I compare this with aa TDK 8GB SDCARD you can buy off the shelf.

Name: SD08G, but printed on the back is SD-K08G
/sys/block/mmcblk0/device/cid: 2750485344303847307ceecef300b900
/sys/block/mmcblk0/size: 15564800 (7969177600 bytes)

Cylinders 968 Heads 255 Sectors/track 63

Total sectors: 15564800
Sector size 512


I don't have or know of any tools to read/check the 'protected area' of the card. Not sure where else to look apart from using VCDS cable when it arrives.

If this works, we just need to cat the information from original Garmin card.
There are cards with writable CID on the market.
