Ok, let’s start.
Step 1.
Press both SET and NAVI buttons and hold for about 5 seconds. Service Mode menu should appear. Go to Versions Indication. Note Loader version. You will need it later on.

Step 2.
Open MMCS screen by pressing Open button. HDD is next to CD insert.

Hard drive is located right under black plastic cover labeled HDD. Using screwdriver gently push to the right and inwards. Cover should come off easily, do not apply force!

Step 3.
Now you’ll need a thorx size 8 to unscrew HDD mounts.


Please note that screws are permanently mounted to HDD casing. Once you unscrew, they won’t come off completely, but by now you should be able to get the drive out by pulling that plastic strap. Do not apply force here either. Moderate pull should do it.

Step 4.
HDD you pulled out is eclosed in a casing. Unscrew four screws, two per each side. You should end up with bare hard disk drive, which you can mount on regular laptop computer.


Hard drives are fragile mechanisms. Do your best not to drop your drive, keep it away from magnets, store in a dry place.
For cautious: Extracting hard drive does not void your warranty. MMCS with extracted drive will retain all settings you predefined (light, car alarm, wipers presets etc.). Radio works. I haven’t tried the CD thou.
