Thanks,Ahhh, ok, i misunderstood your original post. Not something you can fit easily as it is a factory designed option and requires significant components and the correct engine ECM, ABS, BCM & TCM modules and firmware
If it wasn't fitted at the factory I believe it will be exorbitantly expensive to try and fit as an aftermarket option.
Thanks for your advise. We cannot buy the car with this option in our market now because the car did not imported from 2017. If I import by myself price will be very highYou need to find the radar transmission and receiver, the engine ecm, body control module the abs module and possibly the transmission control module along with any associated wiring etc, then there's the factory programming and setup that's required
Just the modules alone would be several thousand dollars even if you could find second hand ones.
It would be cheaper to sell the car you have and buy one with it fitted.
