Ovi Maps 3 doesn't seem to properly support the landscape screen and qwerty keyboard on the E71. here are some examples:
Whilst viewing the map some of the number keys work without needing to hold down the key with the little triangle on it (2, 4, 5 ,6, 8, * and #) whilst the 1 and 0 keys, the most useful, need the function key to be held.
The hints screen (keypad 9) only shows 3 and a bit rows of keys.
If I find any more I'll post an update.
