i have an app that I hacked it sorta but it's called GPSthing.
I got the source code and messed around a bit to output Heading ( N,NE,E,SE,E etc..), Speed, Altitude, and # of sat tracking.
The CPU and PC temperature you see is just from MBM5 using an OSD. I was too lazy to figure out how to hardcode it into the app since im not a C++ programmer.
Here is the link to the program: http://www.coastnet.com/~jas/gpsthing.html
and here is my screenshot of it.
I can post a link to download my hacked version of it but you HAVE to use it at 800x600 res. or it won't come out right. Let me know if you want my hacked version as well.
