Mapping Vivoactive3 hikes on a map?

Well, you can see the hikes on a map directly in Garmin Connect, so not sure why you want to use Google Maps, but if you really prefere it, you can export the activity in Garmin Connect Web in the GPX, or Google Earth file formats (among other possibilities), and then load it to Google maps or any other similar app.

I have Garmin connect on my smart phone....Where are the maps???!

Have no idea what you are referring to and I've been using it daily since Christmas time.

Is there a way to download my hiking track from the Vivoactive3 to a map app or Google maps??

On the screen of each hiking activity (assuming the GPS on your watch was active during the activity):

Yes, if for some reason the map in Garmin Connect is not sufficient, and you want to load the track to an external application do it in the way mentioned in my previous reply - export the ativity in GPX or Google Earth file format and load to to Google maps or Google Earth.

This would be great, but mine doesn't display that. Here is what I see after an activity....

Do I need to go in and turn gps on before I start everytime??

Rather tap the share button on that screen and share the WebLink to the activity here, than sharing the screenshot. The screenshot is not really helpful for telling you what is wrong. One of the possibilities is an expired EPO file: Expired EPO on a Garmin Outdoor Watch

Ok. I will try that. Thanks for the reply.
I turned on gps tonight before my walk or so I thought - then started a walk activity but I must have pressed eliptical so its jigged up. Will try again tomorrow.
