I recently flew IAD-LHR and GVA-IAD, both on 767s. On the first flight, the map didn't work at all (kept saying "this channel not available") though the rest of the IFE did and it appeared that other passengers' IFE did have the map function working. On the return, I was surprised that the map just had the altitude, distance and time remaining in flight on the bottom of the display and not on a separate page. And there was no "local time at destination" or "expected time of arrival at destination" display.

Is this just for 767s or is it a change for UA in general? (And, yeah, I know this is just a minor annoyance. It's not like I plan to bother complaining.)
