In case if you also have the optional accessory Connector Port (EXT1CP2).
- If you see that the blue LED on the Connector Port is lighting constantly: it means the Gateway is in active mode and if the installation was correct, the Gateway can be reached in the car head unit.
- If the LED is blinking, then the Gateway was turned with the Mode switch into bypass mode. This means the Gateway is not available.
- If the LED is not lightning at all (while the whole car is started), then most probably the installation is incorrect, or the Gateway or Connector Port is faulty.
