mac os , glo

As the Garmin GLO is a Blue-tooth device that sends it's position to anything that is Blue-tooth compatible, it would help if you specified which os x device you intend to use with the GLO

 

O.K., this a bit of an unusual set-up, you have a portable blue-tooth GPS receiver sending position data to a not very portable laptop running os x which I guess is in a vehicle of some kind. The problem is software designed to run on a laptop won't be set up to perform 'live' navigation because laptops don't normally have access to GPS position data and they are not normally used whilst driving a vehicle. You will be able to run a mac version of Garmin Basecamp to plan your route to an address, but it won't plot a moving position on it's map. Software that runs on portable devices such as an I-Phone will also expect there to be a built-in GPS receiver and I guess won't take data from a Blue-Tooth device. You may be able to find os x software that will take data from the GLO and plot a live position on a moving map, but I doubt that it will give turn information or any 'speaking voice' commands
