What nav software
are you using? Could be what willjcocks says.
Also you can use an independent gps utility to verify that data is being received into the laptop
. Then you'll know it should work in the nav app if set correctly. Usually the port setting or baud rate is the issue.
edit.... I see you have tried more than one app now.
Here's a free utility I used to test with.
I thought if I used a simple utility to verify operation first, and then integrate into the nav software
, I would be empowered to know it should work if I could get it right. Wasn't very hard, but you are using a more unique gps source than most.
Since your device is relatively new to the market, maybe check for software updates to your mac operating system as well.
edit..... I've used bluetooth and usb connections, but not wifi
to a gps data stream, so that's a new variable to me.
