Being playing with Marble, and have the routing working with some voices converted from Tomtom. the routing is nice and clear, and apart from the odd hiccup (approaching 1 roundabout, voice - take first exit, map - 2nd exit (straight on, icon - turn right)is great.

Damn sight more stable than Sygic...
More convenient than Nokia Maps and OMVoiceserver.

I'm sold on it, but have a couple of requests..

Could it auto-pause and resume music playback via d-bus commands either side of a voice announcement (like Sygic). If the music is playing all you get is a nasty compressed noise, with the music paused or stopped it's fine.

Also I have noticed that quite often I can be approaching a junction, and the relevant part of the map is obscured by the guidance banner. Is there any way that could be improved in future versions. Possibly by moving the banner to the top, or orientating the map so that the direction of travel is "up the screen".

Thanks for a great app though.
