I'm playing with Sygic MM9 now on my N900. Not 100% happy so far, some (early) gripes :

- the routing can be made more intelligent. Now it produces routes, though the fields, through the countryside. Motorway is fine of course but the way to get from my place to motorway is far from 'fast' or 'economical'. I tried both settings. Only a satnav can come up with these routes...

- at a bit higher altitude (more zoom out) lots of detail disappear. even when roads should still be visible, I can only still see village/city names. A bit bizarre.

- no way to use the in MM9 the address data from the phone contacts as route destination/way points ?

-or no other way around, maybe a contacts plug-in, on the detail screen of the contact, include a button : "navigate to here". Would allow more use of contact address data.

But I'm happy I can at least have a 'proper' satnav program on my N900. I do think the visuals, routing quality and integration can be better. But I guess we'll have to wait for version 10 and/or aura to get a bit more eye candy and maybe better integration/intelligence.

Right now it's a bit like the N900 itself, good already as it is but it has a lot more potential

I think overall good value.

Thanks to Sygic to finally releasing it themselves and not waiting for Nokia !
