Fitting of parking sensors

[Kam88]

I have ed30 2007 and it never came with parking sensors how hard is it ti fix OEM sensors expensive and hard ? Or plug and play ?

I don't think its difficult, its routing the loom from the rear bumper to the head unit and drilling the bumper which will be the time consuming parts of fitting.
If you have an OEM unit and want the sensors to work with it go for optical sensors.
