On a previous car I owned, I installed a back-up warning sensor system and found it very helpful as vision was difficult behind the vehicle.

With my Crossfire, I'm contemplating something more advanced. Has anyone installed one of these rear-view camera systems?

I've been looking at several brands...here is one source:

Does anyone have any suggestions or experience to comment about these?

Thanks
