If we get to the point that it really (I mean really really really really really) has to be done, maybe giving some love to improve other piece of navigation software would be better choice whatsoever...? What I mean is Nokia Maps seem to be pretty incomplete (feature-wise: not offline really, etc.) and more and more stuff will stop working with time as they discontinue their services... I remember the Nokia Maps from PR 1.0, and it basically seemed like an online map viewer for me (no real turn-by-turn, no voice, etc.). Software like e.g. Mappero worked way better in my oppinion (btw, I still have it on my N900).

Don't get me wrong jonwil, I don't want to either discourage or lessen your efforts, but even from post #69 in this thread I feel you also consider dropping Nokia Maps alltogether as an option.

Either way, it is up to you, but if you ask me, I don't feel like e.g. Modrana is a proper replacement. Not that it seems to be slow sometimes and freeze some N900s to death (including mine, but in Modrana thread others reported similar issues), but doing so feels basically like replacing notepad.exe with Apache OpenOffice Writer in Windows (Correct me if I'm wrong, I haven't used Nokia Maps since I tried the initial unofficial pathes from TMO that allowed turn-by-turn voice navigation via espeak and for me Nokia Maps still look like an online map viewer with some online routing service - which a simple OpenStreetMap API client written with geolocation plugin, OpenLayers and maybe a N900-local simple proxy-with-tile-catching server/script).

After 10 minutes (not really an edit as I haven't really published the post yet ) - ok, I opened Nokia Maps after maybe years of not seeing them. It doesn't look like megabytes of compiled ARM code... Am I missing some crucial functionality that I don't see in my GUI somehow? I have a boring class on my uni tomorrow, I will try to scratch something similar on my netbook (in order to stop being just a smartass ).
