You should see messages coming from the receiver in the Packet console as well as other visual data.

Note to Navio Raw users – U-blox NEO-6T receiver is configured for stationary mode by default and it will loose fix if the antenna is moved. To change the mode open View – Configuration View – NAV5 and change Dynamic Model.
