2nd SUCCESS. Thanks to Wubster100's work on this. I did buy a new lower grill and radar mount. I am waiting for the new steering wheel switch so I can change the distance on the fly, it is stuck on 3 right now. (I am pretty sure this can be changed with Forscan, but not on the fly of course.)
This mod will only work on 2019 and later Edges. It is limited to 30mph and above ACC.
As far as I know all US and Canada Edges, model year 2019 and later come standard with correct camera in the mirror housing. They most likely have the bus wiring all the way to the front bumper.
Wubster and I are hoping to create a how to guide once we get the steering wheel switches installed and configured.
All that will be needed is the radar unit, radar mount and a short 4 wire harness. Less then 10 changes to be done with Forscan.
