I have an IPAD 2 without GPS, so I bought a DUELXGPS so I may have a readout on my flightguide app but am unable get the signal into the flightguide app or the fourflight. All else works, flightguide charts, fourflight charts, and the duel status tool shows a good signal but nothing show on any of the charts. I know that what ever it is that it is staring me in the face, but I have not been able to find it.... Any help from my friends???
