Hi,
I have a 06 3.0 x5 and I want PDC, I went over the DIY but it seemed difficult to me because of the need for bumper removal. I found a third party sensor on the web . http://www.dealextreme.com/details.dx/sku.10283 . It is cheap and I dont need to remove the bumper (i think).Has any one tried installing something like this/third party parking sensors? Also if I try i need to connect to back up light , is there a switch for back up light ?

thanks
