HI MartinK,
I tried modrana offline mode on N900 as descripted in maemo-wiki. I unzipped tile-file on my linux-laptop, then copied via usb cable to correct folder on N900. But it works only in N900-ONLINE-Mode. Switch to offline, "tile download failed" displayed on map... Turned to online mode it works... Network-Settings in modrana are on "unlimited use of network".

How to enable correct offline-mode?

Thanks!
