The display resolution quality of my backup display picture has gotten exponentially worse over the past two years. Darn near impossible to make anything out at night while backing up a dark driveway.

What are my camera replacement options if any? Is there a CCD replacement available or am I stuck with the OEM CMOS camera? Are any of the aftermarket cameras on eBay or Amazon worth buying considering that the OEM sucks from day one? Can't see spending $400 if a $60 replacement will work just as well.

Appreciate any thoughts or feedback.
