In relation to NE (New) parts, many OEMs change their prices and availability without any notice to dealers or the industry. Therefore, through the REQUEST or RFQ indication, we ask that customers contact us for the most accurate price and availability.

In relation to SV & OH parts, the used parts aftermarket in the aviation industry is not an infinite supply. It is a dynamic, constantly changing market that is significantly affected by and susceptible to highs and lows in supply and demand. Therefore, although we attempt to, at times, we are unable to predict the exact moment when an item may be available. Once again, through the REQUEST or RFQ indication on our website, we ask that customers contact us for the most current and accurate price and availability.

The KMD-540 is the actual MFD unit included in the KMD-550/850 systems. Therefore, KMD-540 + Install Kit & Database = KMD-550. And, KMD-540 + KAC-501 radar module + Install Kit & Database = KMD-850. The KMD-550 and KMD-850 are merely system reference designations. The actual MFD unit does not have the KMD-550/850 part on it.
The KAC-501, 502, 503, and 504 modules can be added and removed to the KMD-540 display unit very easily. Labeled screws are removed from the side panel and the panel is slid back. A screw on the top for the locking bar is removed, the bar is turned 90 degrees counter-clockwise and then pulled up through the top of the unit. For detailed instructions, please view this page from the KMD-550/850 Installation Manual.
