What exact problem are you having? I remember hearing this same line of bull**** from Datalux almost a year ago and I remember how I fixed it. If you are trying to use an extension cable with your Datalux LMV10R and it's not working, then you will need to either get a new Datalux LMV10R2, or get a vga amplifier which Belkin manufactures. It runs off of 9V though which isn't very convenient for a car. Additionally, if the screen won't power up at ALL, the vga amplifier would solve that problem too.
