A long time ago, I had a Garmin 45. When I sent the tracks and trails that I made with my Garmin 45 to the free program on my computer called Easy GPS, I could just put the pointer on the trail shown on my computer by Easy GPS and get all kinds of information like speed, time, direction, etc., etc.
Now, I've got a Garmin Map 78s and Easy GPS just shows me a bunch of lines and no info. I downloaded a new Easy GPS and still no info. Easy GPS seems to be just a program to store tracks now or am I wrong ?
I never used that software but their used forum is here:

Use Garmin's Basecamp program. It is free and knows how to properly interact with your modern GPS.
