Yes, the etrex says "None found" but if you persevere and keep typing
the required city name it will suddenly jump to the name position in
the list.

Err, I don't understand you there. What's the "find a street" screen?
Perhaps, the etrex doesn't have that?

Yes, it's better than nothing.

I believe that squashing the name and the ref together is not the best
thing to do from the point of view of searching but I can understand
that tastes vary. I think that the gps only shows the first label for a
road in the tooltip.

Your request is noted.
