Yea, I just chose the correct COM in each program = to what I setup as outgoing port in bluetooth settings for this GPS. This is no different than any other GPS out there as far as setup - it's just a very useful key chain GPS . The problem with Yahoo Go is that I can't find any way to select COM for gps....not sure if there is a default or if Yahoo is suppose to search and find it (which it appears to attempt but doesn't work). The "External GPS" application is built in and suppose to manage the gps connection among multiple progams - like gpsgate. I've used it in the past and it may or may not work for certain programs - but you can always manage the connection manually yourself if you aren't running multiple gps programs at once.
