I can confirm that the G4X can talk to RealDash over Bluetooth using the MeatPI WiCAN-USB. Here are my settings: WiCAN-USB: Link: Within RealDash, go to the garage, and then open the car door, and then click on the dashboard (bleh, the car clicking thing is really bad UI).  Add a connection > "Adapters (CAN/LIN)" > "MeatPi CAN adapter" > Bluetooth > Wican.... For CAN description file, select LINK > Short CAN   Three issues
