Retrofit Rear Parking Sensors

Our S Line doesn't have sensors and not the easiest car to judge when reverse parking. My wife is main driver and we recently changed her golf for the A4 which is significantly bigger! To be fair though I find it much harder to park than my A3 sportback too so they are as much for my benefit than hers.

I have read loads of posts on this but just wondered if anyone has had this done recently and which company did it.

These look like they might be good as the price includes car paint colour coded sensors and mobile fitting. Not bothered about Audi factory fit ones, just want the basic bleeper type to assist parking between cars outside the house, especially in the dark.

I want them fitting by someone as I don't have the time or inclination to start taking bumpers off etc and messing about with the car's wiring.

These seem to be reasonably priced and provide the exact colour coding plus mobile fitting.

They look good, will speak to local car radio place and see how much they would charge to fit them.
