Thats why I pointed him in the direction I did.
If budget wasnt an issue he could buy the 9861 Ri and he has the best of both worlds. I have just fitted one with sun visor monitors for a friend, DVD playback is brilliant and by using the KCA121B adaptor, I got his X-box working through it.
All the data from Ipod, music Cd, DVD rom, and of course the video output is displayed and controlled by the head unit. It also has quad colour display option.
Very impressive unit.
