  • duster . same problem here with music player display(all orange colour). what to do sir.

  • the display problems its really easy to fix, you’ll have to buy a replacement in ebay or Aliexpress, and dismount the radio unit and and change the display, that will fix the problem.

  • Is it possible to remove the complete glove box compartment to get better access to the fuse box.
