Newbe here with a question: I recently aquired through a trade a general aviation EFIS. Its called an ICDS-2000 and is made by ARNAV which I understand is now Sagem Electronics. I haven't decided what to with it or if I should sell it to buy something else. What is the demand for this unit? or its current value? It does have a recent 8130-3 from Sagem and a current data card. Thank you for your help guys.
