If waas doesn't work it's not too surprising. There's a few reasons for 
this. You may not get a waas signal, they seem to be hard to get quite 
often. Loadstone may not be sending the propper command to turn waas on. The 
manufacturers are free to implement whatever command they want to turn this 
feature on so there's no real standard. You'll only get a waas signal if 
you're standing still so it's really not a lot of help for general
