If you have a KX-TA824, then you'd obviosuly want the CID card. Apparently they rarely go bad, but mine had stopped working after 13 years. BTW, it's easy to replace (press just one of the guides, grab from the edge, and wiggle the old one out. Insert and press the new one, and that's it)

This replaced a failed unit. Would have been completed impressed if it had come in an anti-static bag.
