I just replaced my stock standard stereo in the car with one of those chinese headunits. Found one that was reasonably well spec'd and had the correct dash frame for my korando.

Its awesome because
 - Better navigation (much better than crappy navman unit)
 - Web browser in dash
 - No need for a seperate tablet as i was going to get for the car

I hate bright dash board lights when I am driving at night - the blue highbeam LED on the dash is as blinding to me as the headlamps are to the possum in my path. So I usually have a bit of electrical tape stuck over it to hide it from my direct view.
The orange screen on the stereo I have always felt is a little bright too.
So now with the new one, i can turn down the screen brightness, and if that isnt enough, there is an app called Screen Filter that can add a full screen mask to an android device to make it even dimmer still.

I am a little dissappointed with a few things but they are easily worked around
 - Lost steering wheel control
 - Had to re organise the wiring loom that it came with, could have blown stereo or something else due to their faulty design

But anyhow I am rather pleased with how it turned out - it looks really nice and fits in well with the dash board.

Some of you might remember my old windows xp 7" eee that I had in the dash of my subaru a few years ago. This is much much better.
