I just got a Garmin Oregon 600. I've been using a Garmin Oregon 400t for about 3yrs, and while in some case the maps were poor, at least basic street level detail was there. On the Garmin 600 I just bought it seems like most of the streets just aren't there. Almost anything below a Hwy level just doesn't seem to show up.
I'm attaching an image that shows this. The bottom road is Alt-90 (see Main st / US 90 on the geocaching.com map) the road going SW/NE is Hwy 59. The road out in front of where I work is West Airport. Look how the Garmin has it stopping at Hwy 59. This is a 4 lane road that goes for another 15 miles west of 59 as a 4 lane road the whole way. It's not new either. I can zoom all the way in and this road doesn't even show up, let alone the neighborhood roads around there.
Am I doing something wrong? I've went into setup map -> advanced setting -> Detail -> Most. Nothing seems to have changed.
