I looked again at the PCB for the unit we shipped you and there's a layout error on the GPS connector. The pins are backwards (1 is 6, 2 is 5, ...).
If you're able you can reorder the pins on the wire between the Carloop and the GPS unit. Lift up the white plastic tab holding the terminal with the tip of a knife and pull out the terminal. Reinsert the terminals in the opposite order.
We have another batch being produced right now that doesn't have this issue. We can ship you a new unit when we receive it if you don't want to re-pin the connector.
Sorry about that @Izeroman
