Was wondering if anybody had a similar problem as I'm having with my VCM (2003 Marquis). I have nothing but XXXX displayed for my water, black, and gray levels. I've tried to reset them but it continues to display XXXXX. I checked all the sensors in the input seems to be good in the sensors are showing green lights. Any help would be appreciated. Looks like the sensors will not be available in the future,so I guess I fix it or replace with another system? Thanks Jim
