Has anybody installed a Parrot bluetooth carkit on FEH? There's a new one out with LCD display at http://www.parrot.biz/usa/products/3200ls-color

I've been reading the manual at http://www.parrot.biz/usa/products/pdf/3200ls-color

and installation guide at http://www.parrot.biz/usa/support/in...rer=13&etape=2

but I can't make sense of the diagrams. I have the stock NAV/Radio system, will installation of this device require pulling out the unit or meddling with the wiring behind? Will there be any chance of screwing up?
