Yeah, recent calls works fine, just the Favourites is constantly greyed out and can't seemingly be accessed. Absolute nightmare because the phone book doesn't let you filter by first name or skip sections like A-B-C etc like most car infotainments.
My lame fix was to quickly dial and hang up (before anything rang) two or three people I might want to call which weren't on my recent call history - which is a feature that works perfectly.
