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.
KMD-540 datacards with P/N 071-00161-020X include a major software change to allow the unit to interface to the KDR-610 XM weather receiver. To enable the KMD-540 to accept a software change, Pin 17 on J3001 must be tied to ground. Attempting to upgrade the software from 01/XX to 02/XX without the upgrade enable pin grounded will result in the message:

"An upgrade has been found, but this unit is not strapped to allow the upgrade to take place. Switch the unit off and either strap the unit to allow the upgrade or re-insert the original version of software."
