Nav - how to mark blockage?
 

Unfortunately there are a number of gated communities or apartment complexes in the area I live. This really messes with the GPS routing because some of them straddle two separate neighborhoods and the GPS always tries to shortcut through them (which would be a massive shortcut if they were not gated). Is there anyway to mark a particular point on the map as impassable so I can cross out route finding through gated areas? (Its not just our GPSs, my wife's aftermarket unit does the same thing). I skimmed through the manual and didn't see anything.




Thanks!
