Ok I uploaded the "SerialPassThru" sketch to my arduino, downloaded the Ucenter tool, and it does connet well to the GPS with the Arduino in between.
All I have to change is in NAV5 switch from Dynamic Model->0-Portable to 6-Airborne<1G?Is this it? Is there any way to actually confirm that these GPS is fully capable of >18km=
Thanks a lot!!

Testing the GPS is easy, you put it on a high altitude balloon and if its not configured right it will stop working once it reaches a certain altitude.
