Can the Argus 3000 be connected to a heading source?
No. The Argus 3000 will only obtain map orientation from the long range navigation system. It cannot interface with an HSI or remote DG for heading orientation and it cannot interface with an ADF. The Argus 3000 was essentially designed for the pilot who does not need all the features and added functions available in the Argus 5000 or Argus 7000.
