Rear Sensors from Audi - How Easy is the Install

[Dodge2Dub]

So I'm considering replacing my bumper with an OEM version with parking sensors. Any ideas/advice about how easy it is to install? Are all of the needed connections present in cars that weren't factory equipped with them? Also, is there an on/off switch in the cabin? Is there a speaker that needs to be added to the cabin?

I would assume its a pretty difficult process given that its an audi. i would think that there is a plug somewhere so it might not be too hard but then again its an audi

There have been posts before about guys who have added the sensors, you don't need to buy a new bumper but you do need to drill into the one you have, after removing it from the car. All it gets you is a series of "beeps"... It's also expensive, if I remember correctly. If you have RNS-E I'd look at adding the rear-view camera instead, that's a pretty cool mod.
