Waze uses the GPS data from your phone. As does Google Maps. AppRadio simply projects the results (the nav map) to your head unit. What APR Unchained Reloaded does, is allow the GPS antenna of the head unit be used for the app. (If you have Reloaded, it already comes with the GPS transfer software) However, what I was told by Area51 was Pioneer does not allow that transfer to take place. Here is information I received when I inquired about purchasing the app for using GPS from the headunit:
That app is not to be used with the Reloaded app as it is already included. However it only works with head units that can send GPS data to the phone. Even though your head unit has a GPS receiver, Pioneer decided to not allow sending of GPS data to the phone.
If you want to use navigation on your phone you have to use the phone's GPS. This will work, unless you store your phone under heaps of metal.
Please keep in mind he knows I'm using a NEX 8000. Maybe the problem is specific to that model.
