I ask Siri, " I need directions to xyz main street via tranist". I am presented with options to select Navigon or Google Maps which is great. WhenI select my GPS app of choice, Navigon, the Navigon app launches but the route is not entered; I'm just brought to the main Navigon screen. If I select Google Maps however, the route is entered as it should be. Is there a tweak that would allow me to select my GPS of choice via Siri? AssistantLove might do the trick but it's not iOS6 compatible yet. Thx
