Hey guys. I've been trying to connect a 2002 Toyota Matrix Nav System into a 2008 car. The plugs are different and the diagrams/schematic have 3 wires that dont match. The speaker wires, power and gnd are easy. The wires dont match have to do with LCD Dimmer, LCD (something else, backlight i think), and Illumination. I think i figured out the illumination one.
But the problem is with the display. There are a bunch of static, lines and waves on the screen when you first turn it on. Kind of like a bad tv reception but not exactly. The thing that makes me think it might be cap related is that about 20 min later the picture gets much better. Its doesn't get perfect but the lines/waves get really small and not all that noticeable.
I had a problem with my Monitor before that was cause by bad caps, but it was alittle different. The monitor screen would just be dark for the 1st 20 (or so min) and then after some time would be bright and the picture was perfect. With the NAV its bright when you 1st turn it on. The similarity is that the picture gets better with time, not the brightness but the waves gets small.
What do you guys think? Is this a cap problem? Did i wire this thing up wrong? Or is the unit defective?
I'll take pics of the screen if needed.
