About 20 feet on my P85D. That compares to about 400 feet on my Infiniti home link where I can open the door as soon as I turn the corner and see my garage door all the way down the end of the street. In my P85D, I have to actually drive up on to the driveway to the front of the garage door. It's the shortest range I've ever had on homelink.
Consider me another data point with this value. My old 2004 Pathfinder would open the garage door from 4-5 houses away over its Homelink. The P85D needs to be right at the lip of the driveway. Ugh.
