LXNav V7 Setup

Hi Group,
I realize this is not the correct forum for system set-up, especially XCSoar. I posted on their user group and haven't received a definitive answer that I can comprehend (surely user error).
I decided that my old Cambridge 20 and LNav weren't worth throwing more resources at so I purchased a LXNav V7.
I have a PowerFlarm Core using a V7 cable to connect to the V7 GPS Port. I have a RJ45 cable with Tx,Rx and Ground from the V7 PDA Port to a Soartronic interface IOIO feeding a Dell Streak 5. I have tried all sorts of settings in Communication in the V7 and Devices settings in the Streak. The Streak shows "connected" but "no data".
I've been at this now for three days and am at a loss.
Does any member have this set-up that can possibly set me on the right path? I know it would be easier if I just purchased an Oudie but that's not in the budget.
Thank you so much, in advance. And a case of beer if I see you this summer..
Steve
