I had a CR7 from YWG-YYC 2 weeks ago and the map was working - better than a lot of models currently offered by other carriers, but not as good as a handful of others as discussed already.
The annoyance factor was the TV channels weren't labelled/headed with their genre (unlike the A320 family AVODS) so one had to push "Channel 1" or "Channel 7" etc to actually get into the menu before finding out what particular genre shows that Channel was offering. A lot of extra finger tapping for no necessary reason.
