I agree, and I have _bough_ the Navicore software for N800. It works perfectly on highway and cities.

But it's the worst thing, can ruin your trip if you are planning a trip from Paris to Wien.
Let me explain: it splits maps into regions (for memory savings and to use kinder-garden programming style)
Now, paris is in one region - France, Wien is in another region -German Alps. So it CANNOT plan a route. I have choose Strasbourg as a border point to pass into Germany. Now this is a city (and it has streets also).
I want to go to .... Wien ... but thats wrong ... not such city. Ok then ... Berlin ... wroooooooooong ... ok i want to go east ... ... too many exits

So ... luckily i have some basic nav/geo knowledge ... i know there should be a river to be crossed ... and then i have searched for the nearest bridge (east .... don't forget east ). So now i have again some routing through the streets of Strasbourg and luckily i dindt get lost.

In Germany it worked flawlessly, job done. Quick recovery when choosing the wrong exit ... etc etc .. but the regions problem really sux

it's worth buying, except the region thing.
