    I don't know the specifics of the panels that the auto makers use, but I would suspect that it is very similar to the ones we use. My guess is that the electronics are different to accept a different input but that's all. Who knows. Not me

    I would assume that a 640x480 panel is driven the same way regardless of what board is attached to the back of it.

    Consider LED backlit. Better than standard, but cheaper than transflective.

    But the touchscreen overlay still becomes a mirror when the sun hits it.

    I can see that working ok if it is mounted down low near the gear selector, but up higher on the dash it can be very dangerous.

    I have a 629 led backlit, and it does help, but as sebberry said, it is the touchscreen overlay that is causing the glare. From what I have read, having the screen modified to a transflective is the best ballance between light transmission and sunlight readability.

    There are other overlays that you can apply yourself, but most will affect the light output, or color of the screen

    Whether it's worth it or not comes down to the user. I have a standard EBY701, probably one of the cheapest screens available, and it is completely visible 99% of the time. For the 1% of the time I can't see it (direct, very bright sun), I just put my hand over the screen and bam, problem solved.

    LED backlight doesnt guarantee that the screen is better than standard ccfl. I looked at the specs for the Lilliput screens and the led version (with the Innolux panel) is actually less bright than the ccfl version with the Hitachi panel.

    Well i ordered the 7 inch transflective. I'll let you know how it goes.
    If you don't go touch screen do the sunlight and viewability issues still exist.
