Hi all,

I wonder if anyone can help me with this query i have a Garmin i3 with micro SD city nav v8 uk. i am trying make a back up copy of this using a Micro sd card reader i have copied the files from the original to a new Micro SD card but when i insert it into the i3 it says please use the provided PC software to load maps containing turn by turn route info. The Garmin i3 does not come with any uploading software. there are only 3 files on the orginal card they are the voice files and gmapsupp image file and gmapsupp unl. any one know how it is possible for me to make a back of these to work i my I3.?
One more thing has anyone purchased the Spain + Portugal card, if so does extend into the french Basque country ie biarritz or does it end at the Border.?
I tried to contact garmin but they just said check the website which is of no use at all i ask as i know the uk card has a lot of northern france.

Many thanks in advance

Kev

You can only restore your backup back to the original transflash card it came from. Keep this safe on your hard drive or even better on CD/DVD and if you delete or corupt the original card you can at least re-instate it.

There is a security area on the card that you can't read(or delete) that must tie in the with data put on to it by Garmin

I hope this helps

the 's' of sd stand for 'secure' and, for once, it actually is!

Has anyone using Linux (or Cygwin) tried backing up their microSD card using the 'dd' command? I was wondering whether this would also cause the security information not seen by the file system to be backed up. I would try myself, but I don't have a reader yet, or indeed another microSD card. It would be nice to know that I can perform a full restore to another card, should the original one fail.

Call me a cynic, but I reckon you're actually attempting to copy for profit, rather than back-up.

Don't get me wrong - if you crack it - I'm in!

Sorry to tell you that you can not copy an Sd card, you can back up data to put back on the same card, but it will not work if copied to a blanc card.

From SD Copyright Protection

The card's control circuitry allows data to be read and written (in its The protection area) only when appropriate external devices are detected. A check-out (copying) from a PC to the SD Memory Card is restricted to 3 copies in compliance with the SDMI specification. All SD-Audio products comply with SDMI.

The SD Memory Card copyright protection function has the following features:

Access to the SD Memory Card must be enabled by authentication between devices

A random number is generated each time there is mutual authentication and exchange of security information

(2) Before the content is stored in the SD Memory Card, the personal computer will check whether the card is legitimate, and the card will check whether the personal computer software is a legitimate application. When mutual validation has been confirmed, the content will be encrypted in accordance with the key on each card and the key associated with the content.

(3) Simultaneously, the encrypted content information will be stored on the card.

(4) In the same way, before the semiconductor player reads the content from the card, the player will check whether the card is legitimate and the card will check whether the player is a legitimate device. When mutual validation has been confirmed, the player will acquire the key for decryption.

(5) Simultaneously, the encrypted content information will be read from the card, decrypted by the semiconductor device, and replayed legitimately.

Since this procedure is not possible with anything other than a legitimate personal computer, memory card and semiconductor player, the result is that illegal behavior can be prevented.

Also

The main body of content that was encrypted and stored in the data area can be copied freely to another card, but, since the copyrighted information of the content stored in the protected area cannot be copied to another card, this means it cannot be reproduced or copied dishonestly.

Moreover, even if a dishonest copy of the copyrighted information stored in the protected area could be made in some way, this information is still protected because it has been encrypted in accordance with the key that is unique to each card so that it cannot be decrypted.

If a particular SD device were to be hacked, and this access procedure were to be analyzed, there is still a key revocation system that will invalidate the key of the SD compliant device that has been hacked by altering the keys of future cards
