I am sure there are other brands that let you select a background picture. My old Kenwood DDX6019 could not but I seem to remember the 7019 and 8019 could.
I have a new DD (old one stolen) stayed with Kenwood because of the add ons and versatility, New head unit is the DDX714 w/ Bluetooth. This allows me to use the add on Kenwood NAG-G510 NAV I all ready have. New unit lets me set background pictures, screen and button color. i-pod and usb let you add album art with music, decent graphic equalizer, speaker type selection and more I am finding everyday, sound quality is excellent although the bluetooth add on I had with the old unit sound quality is better I am still playing with the adjustments to see if it can be improved.
It is a good unit and looks stock in the dash, total price new was 620.00 I remember seeing re-furbs. for right around 400-450 on line. (No picture stole camera too)
