I agree, then screen does seem to angle down quite a lot. It might be an attempt to block out sunlight or maybe it's just for short people! 
The nav works pretty well, the controls are on the right indicator stalk and are pretty easy to use. You can't enter postcodes, only addresses and streets which is ok. It's as much as can be expected from a <2002 nav unit I guess.
