At or just before reaching the final fix on the CLT JONZI2 arrival we saw momentary fail flags for GS; VPITCH; the flight plan dropped out (but left the approach in) and time and fuel calculation displays showed dashes. AP was engaged. The aircraft started to turn; reaching about 110 deg M before I got heading mode engaged. HDG was just being set to 090* per just received ATC heading instruction but I had not yet selected HDG when the turn started.In case this was a 5G issue I pressed the flight data event button. Don't know. The STAR has a 090 terminating HDG for the runway in use; which happened to match the ATC instruction just received.
Air carrier Captain reported autoflight anomalies on initial approach into CLT; citing 5G interference as possibly contributing.
