At first, I thought he was saying the screen is too small, but he said the maps are too small, which is different. I have used many GPS with smaller screen than the n900 and they all worked fine for use in a car. It is just a matter of proper font and feature size. Voice announcement is certainly worthwhile, but not needed. Most of he GPS devices that I used could beep at best. I would prefer (clear) voice, but do not need it.
