New HU with front and Rear PDC

[wildmonkeyboy]

I just put my deposit down on my 2nd hand '07 Plate 1 series . Loved the car hated the stereo (it comes with the basic set up and Business HU) I have removed my head unit from my Type S and want to have this fitted. I have found all the parts and info that will let me do this including keeping the rear PDC working, but cant find anything about keeping the front ones.

I just phoned my local sextons and they have told me it's not possible.. HELP . I don't want to have to make them redundant (seems a shame on my new car!).

The HU I have that I want to put in is a Pioneer DEH-P6000UB and I use it with my Iphone. Any other info needed let me know.
