4000895-3004, CN-2013A, Bendix Avionics Nav / Comm

Bendix CN-2013A Digital Nav/Comm. P/N 4000895-3004. Visually it checks out ok but I can not test the unit to verify condition and I don't know anything about the history of it. Radio has been converted to 115V according to a label affixed on it, most likely to make a ground radio. 10ths plastic knob is also missing as shown on photo but it is easy to replace. Sold as a core only, as is, no returns will be accepted.
