RealDash CAN + Arduino + GPS

Hi guys,

I started a project using an Arduino + External GPS + Bluetooth to communicate with a Tablet.

The doubt is how can I communicate the GPS Lat and Long sent by arduino to “MAP Gauge” in realdash? Im using a RealDash CAN.

When i use a Tablet with internal GPS the MAP Gauge is totally OK, but when the Tablet doesnt have a internal GPS I dont know how can I send the arduino GPS Lat Long to RealDash.

The problem occurs only for lat and long, for GPS speed the communication is OK with Arduino with GPS → RealDash Can, but the MAP Gauge doesnt have the “LATLONG” options to connect.

I need to investigate this. It may be that lat/lon received from RealDash CAN are overridden by expected internal values.
