Is there independant volume for different sources? Yes - you can set the sound for the hands free phone at a different level than the radio. There is also an option for the master volume to reset at restart. So if you have the volume up real loud on the way home at night - it does scare the hell out of you the next morning when you head out for something to feed your hangover :P How does the lcd screen perform in daytime driving? There are three levels of screen brightness shown on the main menu - but if the sun is shining directly on the screen it does washout. This doesn't happen that often and you don't drive around looking at the screen all the time. I haven't noticed this is a particular problem - the screen has a matte finish and doesn't pick up every reflection. Same at night some dim nicely and dont distract, while others stay way to bright even with dimmer activated and annoy? Its similar to the small trip computer screen in brightness at night, but when you turn on the lights it automatically dims to the night setting. Its a big screen so you definitely need the dark night maps on the navigation software, but the audio menus are mostly black so it isn't a problem. I have nothing to compare it to - but I haven't had anyone get in the car at night and say it was too bright. The other thing I like about it, I forgot to mention in the earlier post, was that the quality of the sound is much better than the KXS OEM unit it replaces. I don't drive on many long trips - I only work 5kms from home - so it isn't until I go for road trip that I appreciate the sound quality. The only thing I would add is a small under-seat sub - it has an output for this. The steering wheel controls also work very well - volume changes fast and iPod songs or radio stations change with the < & > buttons. The 'mode' button changes between ipod, radio, dvd etc. The integration with the car is seamless.
