They were under the impression that you get all trails that are on a USGS map and have so far told their customers exactly that. They were totally surprised and couldn't believe it. I returned the 24K maps and while doing it showed it to the employees at REI. It still doesn't make sense to me to have a trail name in the list of POIs but not the actual trail shown on the map. I contacted Garmin and they told me that this is in fact correct and due to different data sources that are used. In all 5 trails were displayed on the US TOPO maps (100K) but not on the TOPO US 24K CA/NV maps. Plus, I don't know how this would work if you are using SD maps. There are some tutorials on the internet about how to do this, but its a bit tricky and none of the tutorials are perfect. It is possible, using free software, to make your own transparent, routable trail map which you can install on top of a Garmin map. Too bad, because routable trails are very cool! Thus, Garmin's trail data is incomplete and often highly innacurate. They focus pretty much all their effort on road nav. The reality is that outdoor maps are only a tiny part of Garmin's market. Unfortunately, the most likely problem is that Garmin's new maps just don't include the trails. Have tried zooming way in on the trail? If the trail is only appearing at very close zoom, you can calibrate that under map settings. I suppose it could be something with how your zoom details are set. To troubleshoot whether its a setting on your device, I'd recommend that you see if the trails appear in MapSource - but can you view SD-card maps on the computer?
