I think there is an adjustment procedure I have seen somewhere. I think it's on the unit not the LCD. Mine did not require any adjustments. I just did this for tinkering purposes. I purchased the unit with the bad LCD for $30 and had a spare good LCD. It's good for keeping my mind at peace in these current times. I do want a widescreen NBT looking android unit for my X5. I do have an NBT setup but the retrofit wiring is expensive...
