You can adjust the brightness. Check the manual, (nerd)
Does it come with a kenwood sticker for the windscreen?
I bought this unit from Halfords last year on a similar "open box" type deal. It comes with the DAB aerial (windscreen mounted), external microphone and it had the correct leads for connecting directly to the iso harness in the car. The unit performs very well, my only criticism (and it is only a minor issue) is that the display is very bright. Fine during the day as it is visible, but for night time driving it can be distracting as it almost illuminates the inside of the car; now might just be an issue with head unit not detecting the "headlight on" input (my car is a 1999 model), but the correct input is connected.
Will this fit a mk2 Ford Focus? Looks same size. No idea what extra cables i'd need, never replaced a stereo before...
Thanks, does it come with dab areal?
