A step-by-step tutorial for Harman MHI2 region conversion between US/JP/KR/CN and European firmware.

Prepare the unit, vehicle, and yourself

  1. Check your currently installed firmware. You you have a very old version, your unit might need firmware update first in order to have More Incredible Bash working. And you need it for this to work.
  2. Make sure that power is stable:
    • if working on bench, make sure that the 12V power supply can provide needed amperage
    • if working in vehicle, make sure that the car is connected to external power source or the engine is running. Vehicle equipped with keyless system should have the fob close the the keyless antenna during the procedure.
  3. Make sure that you know those:
    • REM - Red Engineering Menu
    • GEM - Green Engineering Menu
    • SWDL - SoftWare Download
    • FEC - Feature Enabling Code
    • SWaP - SoftWare as a Product

Tools and software

Convert MHI2 unit to European Firmware

Install More Incredible Bash

  1. Insert SD card with More Incredible Bash
  2. REM → Update → SD card → install More Incredible Bash

Prepare unit for EU firmware

  1. GEM → m.i.b. → advanced_settings → eu_conversion → convert unit to EU. It will end with "reboot (..) and run conversion again"
  2. reboot the unit, and run the `convert unit to EU` again
  3. ...and again - you see "Now you can insert (...) and update".

Prepare update package for custom full SWLD

  1. GEM → m.i.b. → advanced_settings → swdl_fw_updates → Enable user defined SWDL → ENABLED
  2. GEM → m.i.b. → advanced_settings → swdl_fw_updates → Ignore Region and Variant → ENABLED
  3. exit GEM by going to RADIO. Don't reboot the unit.
  4. insert FAT32 SD with target firmware
  5. REM → Update → User defined → RightButton → Set all to [Y]
  6. if you have premium sound system with external audio amplifier (Bose, Dynaudio, Fender, Bang&Olufsen...), set the amplifier (AMP16*APN / AMP_BAO_P3 / Bose6416*) to [N], because we don't want to update the amplifier. You could do it, but you will need to upload correct parameters to the amplifier afterwards.
  7. if you have Audi A3 8V (AU37x), set the FC2H37xE to [N].[1] This is the display mechanism firmware. If you flash it with the EU firmware version, the mechanism will stay permanently open.

Start the EU firmware update

  1. scroll down → Start update; wait...
  2. In "Device summary" scroll down → Resume
  3. wait for reboot, go to MMI settings and set your language

Patch the unit

Now let's handle FEC / SWaP codes and Component Protection.

  1. GEM → m.i.b. → patch_unit_aio → PATCH NOW
  2. wait fot the patch to be applied
  3. after patch is done and unit is rebooted, go to REM and check if new license keys/FECs are installed and valid.

Install options

EU Maps

  1. GEM → m.i.b. → navigation → check coding → SDS region → Europe → Save changes
  2. VCDS/OBD11/VPC → module: 5F → Basic Settings → Formatting Partitions of Internal Memory → Navigation Data Base → Go
  3. insert SD with MHI2 EU maps
  4. System Care → System Update → SD1 → Start Software Update; wait...

Speedtrap PPOIs

  1. insert SD with PPOIs
  2. System Care → System Update → SD1 → Start Software Update; wait...

Gracenote

  1. insert SD with Gracenote update
  2. System Care → System Update → SD1 → Start Software Update; wait...

Radiostation Database

VW / Seat / Skoda

  1. download RSDB update from https://www.phonostar.de
  2. insert SD with RSDB update
  3. System Care → System Update → SD1 → Start Software Update; wait...

Audi

  1. download MH2P RSDB
  2. extract the package, find the VW_STL_DB.sqlite file
  3. copy it to More Incredible Bash SD card, to /mod/RSDB/ directory
  4. green menu → m.i.b. → multimedia_system → radio → radiostation_db → Copy RSDB to unit; wait...

If you use the VW/Seat/Skoda update, it will result in small logos with a thick border around them. This is due different resolution of the textures (160x120 vs 320x240).

Boardbook

Audi and Porsche only

Check 5F → Long Coding, if the boardbook is enabled

  1. insert SD with Boardbook
  2. Settings → Boardbook → install; wait...

Finishing Touches

Video In Motion

TODOOO

DVD Region

TODOOO

Fix B201A SVM fault

  1. VCDS/OBD11/VPC → module: 5F → fix B201A fault with "i'm so XORy" calculator

or

  1. GEM → m.i.b. → SVM_fix
