Logan, what version are you running?
I have the latest one, and the latest maps (I have access to their FTP server

) and the postcode issue is gone for me. I think.
Can you give me a postcode your having trouble with?
I want to like Sygic. I really do, the interface is by far the best on S60, and I love the maps, no garish colours, and its easy to see.
But the navigation...ahhh the navigation.
As well as U turns at roundabouts (Im not joking), directing me up one way streets, and generally ignoring roads just before any turns Im supposed to make( i.e. telling me to take a right, instead of second right), its just not reliable enough for me to use.
Its also infuriatingly bad left right issue when not needed.
Sigh.
Oh, and you saw my post with the screenshots of the new Garmin coming out? Looked hellva lot nicer.
