I, too, am using GSAK, GPX Sonar, and MS Streets and Trips. I love it!
I currentlty have 2 challenges.....
1. I cannot create a large map area to transfer into my PPC. I can send a fairly small map area and all the cache pushpins show well.
2. Given number 1, I have created a number of smaller map areas that I can load to my PPC. I get the same map each time I open one - for example....I have 4 maps - "East", "West", "North", "South". When I open "East" - I get the East map and it's correct information. When I open "West" - I get the same map/info that I get for East, etc. I have named them unique names so am not sure why this happens.
Thoughts?
Suggestions?
Thanks!
