I am sorry to say that it does not send gps signal . When i use Waze , it disables GPS signal on my Note 3. But other nav apps like Sygic,Google Maps etc., it works but uses my phone's gps signal not the unit. Similar issue when i had the avic-z150bh. I believe when appradio app detects that it is connected to a navigation unit, and try to start the pioneer app uses(like waze) it disable the gps on my note 3.
