First off, thanks for a great application, gnuite. After having it installed on my 770 for ages, in the last week I've been using it far more, thanks to finally purchasing a GPS receiver. This experience with the program led me to notice a few things that might improve it - I hope you don't mind I wrote a few suggestions down and posted them in my blog. I'll write more in the next few days.
