GX-450 not pushing coordinates

GX-450 is not pushing X,Y coordinates. Has internet, is reporting to the AVL server as configured except that the X, Y coordinates are coming in as 0.00000000,0.000000000

We have it reporting to two different services and it is not reporting to either one. We’ve checked to make sure the antenna connectors are snug but not over-tightened.

We’ve got the shark fin MIMO antena. The unit is less than a year old.

Any thoughts?
