ANY MODIFICATION ON HARD DISK MAY ALTER MMCS CAPABILITY TO LOAD DATA. DO IT ON YOUR OWN RISK.

The tools needed:
I would try to update my navi using a copy from another disk.
The tools needed to unlock the hard disk are below:
1. One screwdriver
2. One torx size 8 (see img)
3. One IDE adapter from small form to regular IDE (see here and here - both sides) if you use a desktop PC. For laptops, it connects directly.
4. The unlockhd program from iso file (the package is available here or here). You have to write it on CD and boot from it. NO OTHER HDD SHOULD BE ATTACHED EXCEPT THE MMCS' ONE.
5. The unlock key: B2BAB3BCB0DFACBEB1BBBEDFB1ADD2CDC9CEBAB2DFB19E8996DFAA8C9A8DDFDF - for loader version 261EM (or B2BAB3BCB0DFACBEB1BBBEDFB1ADD2CDC9CEAAB2DFB19E8996DFAA8C9A8DDFDF for 261UM)
6. One computer with IDE bus.

Procedure
1. To find out what loader version you have:
    a) hold SET+NAVI for about 5 seconds to enter "Service Mode" menu
    b) press Version Indication
    c) note somewhere the Loader version. The key calculation algorithm is presented below. For example, for 261UM version, the key is B2BAB3BCB0DFACBEB1BBBEDFB1ADD2CDC9CEAAB2DFB19E8996DFAA8C9A8DDFDF (I bolded the difference between 261EM)
2. Flip the screen (push OPEN button in the lower left corner), pull the HDD plastic cover, gently.
3. Unscrew the two screws which holds the hdd. Use the torx. Pull out the hdd.
4. Connect it to IDE bus and power supply.
5. Start the computer, boot from CD, and pick option 3: "Boot linux with locking/unlocking utilities"
6. Wait for root@Xbox-HDM:/1 prompt
7. type unlockhd -p <KEY> (Ex. unlockhd -p B2BAB3BCB0DFACBEB1BBBEDFB1ADD2CDC9CEAAB2DFB19E8996DFAA8C9A8DDFDF). Double check if necessary
8. The key depends from unit to unit. See below.
9. If the operation is successful, running fdisk -l command will show the partitions (very similar as below). (thanks rcpax

)
10. Now you may turn off the computer. The disk is unlocked. You may use it with a Windows computer as a regular disk.

Key computing algorithm
Thanks to brian360, the string sniffed when MMCS negotiate with the hdd is
    BAB2 BCB3 DFB0 BEAC BBB1 DFBE ADB1 CDD2 CEC9 B2AA B1DF 899E DF96 8CAA 8D9A DFDF

The password is 32 bytes long but transferred at 16 -sixteen-bit words, so the MSB of each byte is high. It turns out that if you invert all of the bits of the password you get this:
    454D 434C 204F 4153 444E 2041 524E 322D 3136 4D55 4E20 7661 2069 7355 7265 2020
Decoded ASCII is:
    "EMCL OASDN ARN2-16MUN va isUre "
After swapping the byte ordering around you get:
    4D45 4C43 4F20 5341 4E44 4120 4E52 2D32 3631 554D 204E 6176 6920 5573 6572 2020
which in ASCII is: "MELCO SANDA NR-261UM Navi User "

MELCO - Mitsubishi Electronics Company
SANDA - the company's Sanda Works facility
NR-261UM - loader ID

The password used with the 'unlockhd' command was actually byte swapped, so if you try it, use this as your password:

b2bab3bcb0dfacbeb1bbbedfb1add2cdc9ceaab2dfb19e8996dfaa8c9a8ddfdf

An excel sheet to exemplify the algorithm is available on PM. It requires Analysis ToolPak from Excel Addins.
The disk is locked again when you insert it in MMCS unit.

I just put all this stuff together to be easier to understand. Thanks brian360, otaku, GPSeek, oly_57mpg and all the others I could omit.

Respects dude.... thanks for the share.

-edit-: Just saw this:

9. If the operation is successful, running fdisk -l command will (??) the partitions (very similar as below).

I think a word is missing.

Good luck and keep us updated. Hope get my hands on the updated files too.

You are right, I corrected. The missing word was "show"

Thanks

Greetings! My name is Igor, and I live in Germany. I have brought Outlander II of USA. Now I have some problems in which I hope, that you can help me... Whether Probably on MMCS to remember European maps? Whether probably to change Fahrenheits, miles and gallons to kilometers, litres and Celsius? Whether to remove protection of zone DVD? You do not know, who could make it to me for money?
If it is possible, I know some potential clients!
Thanks!!!!!

Hello Igor! I'm Lukasz from Poland. I've also imported 07 XLS Outlander from USA :) I think we have the same problem!!!

Navigation is to USA Only, i've found MMSC from EU Outlander and now i'm waiting for delivery. I've spended hours on finding how to upgrade MAPS to Europe...even Mitsubishi Service in Poland doesn't know how to do it. You can order an upgrade DVD, but it costs about 600 EURO, and you dont have warranty that Your maps will be upgraded to EU!!! :(

You can change Miles to KM and FH to Celcius in MMSC Options, this is not a problem. Just Press SET - SYSTEM - UNITS :)

I have problem how to change Clock Time!!!! This is terrible, there's no such thing like "adjust time/clock" !!!!! Only i can change Time Zone, and DayTime.

Maybe rdenis can help us!!!!!!

I can send you a clone image from my disk (Outlander '07 Europe). The operation needs an extra ATA notebook disk, not SATA (just to be sure you don't screw yours with incompatible data).
Disconnect the battery for about 30 minutes, restore that new disk from clone, put it inside MMCS, reconnect battery, restart the unit and see if everything is ok. If you are satisfied, overwrite the original disk (is a little bit more special that an ordinary notebook disk - automotive grade - so in real life you should use that one) and use it. If don't, put the original hard drive back as it was before.

ATTENTION
After placing a disk inside MMCS, it will be locked with the same pass. To use it further, you need to unlock it.

PS
To unlock the DVD there are 2 ways:
1. Rewrite firmware in DVD player itself (not MMCS but the DVD)
2. Trick the MMCS' operating system to fool the player that the disk is the correct region (kind of AnyDVD for PC)

Both are a little (more) difficult to implement

Regards,
Costin

Clone of disk would be helpfull. I have another ATA 2,5" Disk, and also i have external USB (ATA) adapter. But tell me does Norton Ghost or any other clone program will read that disc? When i'm plugging in my 30GB Toshiba Disk - Windows does not recognize partitions (disk is locked, i've read about it).

Please write more about Unlocking DVD, or upgrading firmware! Also do you have any Idea how to change Time?

Thank You for any help!!!

Just put in my 2 cents worth, I belive rcostin use Linux to unlock the MMCS drive first before cloning.
