has anyone install through dealer or aftermarket wtih factory Nav. a back up camera i saw the one porsche site for around $1800 any one done this or better to go with aftermarket camera instead? which brand would work with our Nav unit.,thanks in advance.

 

I beleive the price is $1650 for the CT and something like $2800 for the CS and C models.

 

can it be retrofitted?

 

I like the sensors more

 

I did. I got an audiovox kit that has a screen in the rearview mirror. It is awesome!!

 

try www.navtv.com

 

Problem with the nav tv is that is $1100 just for the conversion. Plus is voids any warranty on the nav. No camera at that cost either.

 

Has anyone with the camera tried using this when backing up to attach a trailer?

 

I have. It does help a lot. i have my camera mounted in the bumper above the trailer hitch.

 

wow this is awesome !

do they have to cut the rear bumper?
