Is this real? Unit ships with full memory?

Because the 67 series has only an internal 16gb memory and if it comes with the preloaded TA maps for Europe or North/South America there should be (normally) about 3-4 gb free memory left (?). Yes, 16 gb memory is not much these days, because maps are getting bigger and bigger. But 94% used memory seems to be much. Luckily you can add an sd card. 

The preloaded TA maps are detailed. Which TA map is installed on your device and does this map match your location? Have you zoomed in? Perhaps you bought a device with other then the necessary TA maps for your location?

You can tell what maps are on the device. From the Map page itself > (click) Menu > Map Setup > Configure Maps. You will PROBABLY see Worldwide DEM basemap, and TopoActive for various regions. There may be several TopoActive regions. For example, if you bought the unit for North America, you might have US, Middle America, Canada/Alaska.

This page will also allow you to turn maps on and off. If you are not seeing what you expect to see, you might check to see if the corresponding map is "on". And, as volker points out, what you see can vary by zoom level. You can be zoomed "too far out" OR "too far in" for some features.

You don't say what map you bought. Typically, Garmin "more detailed" maps are quite large.

The lack of internal memory on recent Garmin handhelds is a sore point. For the iR series, Montana 7x0i, 66i, 67i, etc. - they are ALL undersized. The conventional wisdom is to install an SD card. Use Express to move some of the maps to the SD card. This allows you to stop worrying about space on a daily basis.

As far as the Garmin web sites and mobile apps go - confusion reigns.

Since you mention "logging in", you should be aware of Garmin's obsession with single signon (SSO). In general, if you sign into any one Garmin property (for example, explore.garmin.com or these forums), you are automatically signed into all other Garmin properties (including mobile apps) with those same credentials. AND if the account does not exist for one or more of the properties, Garmin automatically creates one for you. This is OK if you only have one Garmin account. But if you have more than one (for example, if you have more than one iR device on different personal accounts, or if you sign into forums with different credentials, or whatever), this makes a very confusing mess.

As far as route planning goes - there are multiple options. The map page at explore.garmin.com allows you to create a route, which will eventually be sync-d to the device (via a mobile app like Explore - yeah I know). You can also create the route in the Explore app. (I have no experience there because I try to stay as far away from the mobile app confusion as possible). Inexplicably, routes created in either of these ways are limited to 200 points. Nobody knows why, but everybody complains.

In the Explore app, routes are known as Courses. (This is mostly a meaningless distinction based on the file format. More confusion.) The option to create a Course is hidden behind the + icon in the upper left corner of the map page.

You are probably on the right track with something like Gaia for route planning. Exporting from Gaia and moving the resulting .gpx directly to the device bypasses the 200 point limit. (Importing the .gpx through explore.garmin.com or the Explore app is likely to "thin" the path to get it below 200 points. Because we all like less detail?)

It does appear that it ships with TopoActive maps for worldwide locations, and that you can move them to the SD card. Next step is buy an SD card and then see if I can move them. I bought the Topo US 24k West. Yeah, I didn't zoom in enough on the Topo Active North America, so that's a dumb mistake. I think I got tired trying to jump through all the hoops. But after using Gaia GPS on my phone, the Garmin systems seem to be both complex and opaque.

Hello 5376700 I am not sure what the percentage should be or what your device specifically comes with. However, you do always have the option to manage the mapping on the device and free up space Managing Maps on the GPSMAP 67 Series With Garmin Express.
