Old cacher needs help with GPS in How do I...? Posted May 28, 2018 I am having a problem after I download the pocket query to my files. For one I am not sure how to unzip the file and two how to get that info to my GPS. I am feeling kind of dumb here. First time going away from Garmin and using Magellan and it doesn't seem as easy as it used to be. Back in the day I would use GSAK but shoot in 8 years I would think we have advanced from that.
