Hi Bilal,
do you have any instalation videos? I have bought the xtrons head unit and MOST, but i cant get it to work, screen works, but sound and climate controls doens`t. did you need to modify the iso harness at all? i have loads of conectors left loose from the original screen. mine is the original navi from 2007 with mark levinson, can`t seem to find any info online at all
thanks
