Been making progress, have my project talking on UART4, WNC, Pubnub - started into adding the Xadow gps module and it is recognized but it not locking in - have left it outside in my car (it's a car dashboard project!) under the windshield, just a little bit of a tree but other than that open sky. This is all I get with the default out of box application Avnet_ATT_Cellular_IOT:
App Firmware: Release 1.0 - built: Dec 15 2016 00:10:56

Will let it run a few more hours but don't know what else to check for debugging.
