Love my 2007 C4S Cab, however visibility rearward is poor with the top up. I wish I had the parking sensors installed when ordered. I am told they are not retrofitable. Anyone have any commentary on that? (Please - no "My top is always down" jokes!)
Also, It would be nice to have a rear mounted video cam play through the PCM/NAV screen. Any one know if such a thing exists?

 

The PCM retro video question is presently playing under Cayenne!!
