I've been using Modrana more frequently, and it is excellent. I have it running with offline maps, offline routing, and voice navigation (using the en1 embrola voice with espeak.

Thank you, MartinK for this great program.

I have a couple of questions which I didn't see addressed (or which I possibly missed).

Is there a satisfactory offline POI database? Or an address database? Having the POI database at least would be great.

Also, does anybody successfully use the voice navigation via the FM transmitter? It doesn't work for me because if I'm playing something the voice is not loud enough, and if I don't play something then the FM transmitter goes to sleep and doesn't wake up fast enough when directions are spoken.

NOTE: An easy, but inelegant, hack for my second question is to play a silence file via Media Player on a loop. Any other alternatives?
