[CondorXC90]

Parking sensors for the fronts need a loom and the volvo sensors - the loom attaches to the control box in the rear and the sensors into the bumper.
Definitely not worth over £800!!!

There are independent companies who will come to you to fit front sensors - google Dolphin parking sensors as an example - or just generally google front parking sensors xc90 and a number of such companies pop up. You could also buy a wireless set built into a numberplate surround for under £50 ......wiring is simple and no bumper cuts needed - will help your tight parking in Brighton albeit not perfect and not OEM.........

You could call FRF in Swansea and ask for a price for the loom and sensors and get a decent indy to fit them? worth checking out the pricing if you want the OEM front sensors
