PDC & Rear-View Cam

[daus318]

Hey guys I just placed an order for an X5 35d but I decided not to get the Technology Package. However, I'm now having second thoughts.

Basically what I need to know is first:
-How easy is it to park without PDC or does PDC make it much easier?
-I'll be trailering a boat and was wondering how effect the rear-view camera is for hooking up to the trailer and then launching the boat into the water.

I really don't care about Navi so I hope you guys can give me some input on the PDC and the camera. Let me know. I just may have to contact the dealer to update my order.
