Try this for me, Put your BT dongle in another computer and pair the Earthmate. Then pull the dongle and put it back in the Flytouch.
Ok, why try this?
I was able to connect both my Apple Bluetooth wireless keyboard and Apple Magic Mouse to my Flytouch 2 (10.1") using this method.
I have not had any luck getting my Earthmate to "talk" to any of the GPS "aware" apps I have tried. You are speaking of a program "CoPilot Navigation" which I do not have and I'm interested to see if you can use the "pre pairing" trick I'm using.
Good luck!
