I've got a GP-E2 for my Canon 5DS-R and it works great, adds all the GPS data onto each image (though some locations are way off so need to change them), but I also used the GP-E2 for tracking my route, but when I go into map utility on my mac it says it can't find the device.

Any ideas what I need to do as I'm getting very frustrated with not being able to view all the data I've collected.

Thanks
