The SV6 interface seems to be fine now and the receiver works well.

Nice, I just put up a new version 0.5 which has the NMEA parsing changes and also hijacks all the right buttons.

Could you send me both of those routes. I wonder whether there still is some python problem that created a badly formatted track file... Oh, you're probably using Windows which does 'automatical CR/LF' translations if you don't open files in binary mode.

Small change, I just included it in v0.5, but basically it is open("route", "wb"), that 'b' is significant here.
