Important points about the conversion:

  • To do the conversion you will need to send us the:
    A: HMI-box
    B: Radio (see info/pictures).
  • If the car doesn’t have navigation it’s NOT possible to convert! It’s missing hardware and you will need to replace the HMI unit. (See photos above.)
  • If your 2019 vehicle is running maps off of SD-card, then we are not able to convert it!
  • AFTER conversion/upgrade you will need to contact us for upgrades which is uploaded via USB.
  • The radio and HMI can not be moved between cars! Please put a note on each module so that it is clear beyond doubt to what vehicle the modules belong. 
  • Note: Your vehicle will not start if the HMI is missing! Make sure it is parked in a convenient location.
