if i have an aftermarket rear parking sensor system, are you able to retrofit the factory fitted one? my plan is to have the '09 bumper fitted with the sensors that come from the factory. would this be (easily) possible, or do you reckon i'm better off reusing the ones i already have? i really dislike them because they're not flush with the bodywork and quite sizeable. however they have more pleasing "beeps" than the factory fitted one i had in my 2005 model.
Yes, can remove old system & install factory version & tbh its really upto you what you think is best as your the one seeing the sensors & hearing the beeps mate.
