Has anyone got their 4800 baud GPS reciever to work with the new version?

I tried various configurations, cant get it to work. Seems like each new version, I go through this.

Last go around, I experimented with various variables and ended up with 8 as the best readtime. (Makes sense, as 38400/8=4800)

Anyway, if you have it working with your 4800 baud unit, can you post your config.txt file?

Also, do I have to make new maps with the new version?
