Hi guys looking into getting a backup camera kit for my FG G6 MKII that's close to factory.

I have been told there are 2 guys on ebay that sell kits one cost more then the other and one requires the backup camera to be activated by a Ford dealership the other does not.

There's this guy at $429+ posatge $14.90 & + activation fee from Ford $120 total cost $563.00
This is pretty much factory setup so no option for parking gridlines.

And this guy at only $395 + Free Postage total cost $395.00

Still have use of the factory display like it is factory but uses a program box and uses aftermarket camera but I can choose if I want parking gridlines that I do want.
