OK Yall Im Stuck!!

Did you uncheck your City Navigator Maps on your GPS unit?

You must do so because they take priority over the TOPO maps.

If I uncheck City Navigator, I cant go anyware
I cant put in any states, addresses it says none found Nata.

I have'nt taken it out on the road yet maybe it is working and I just dont see it.

I installed a topo map on my nuvi and when I uncheck City Navigator, I see a typical topo map with the contour lines, bench marks, ponds, streams, bridges, mine shafts, etc. I believe the intent of these maps is that they will be used in a "hand held" mode.

The built in POI database, addressing and routing are all tied to City Navigator, and as such are not available. Favorites(Waypoints) and Custom POI should work, routes will likely be as the crow flies.

Think about how you would use a topo map with a compass in the woods and this should start to make sense.

Thanks fellow Texan Ill play with it some more/.

I played with it some more its working.
Turning off City Nav did the trick..

Thanks Motercycle MaMa and TXRVer..

PS. Topo wont work with City Nav on, But US Recreational Lakes and Fishing Hot Spots does work with City Nav turned on. I had to zoom way in on a lake to see all the Boat Ramps and water depths to see them.

Hum, I will have to try this. I have TOPO for my Legend and did not realize I could load these maps on the nuvi.

I will have to try that out...do you load them on the SD card or to internal memory?

I used MapSource to install it. If there's another way, I'm not aware of it. It loads to internal memory.

I grabbed some of the 1:24000 state TOPO's from GPSFileDepot just now. I will see if I can have Mapsource put some of these in as I would like to have them over TOPO's 1:100000.

I was able to choose the SD card for the download im Mapsource in the drop down menu after it found my device.

So I am creating a SD card of nearly 1GB of my usual haunts in the West (All WA, all ID, Northern UT, Western CO and Central and Western MT). I hope this works.

My Legend has such limited memory (24MB) so I am constantly changing the maps in it. If this nuvi can have a repository of Topo...expecially the 1:24 series that will be super handy.

I may change out my Legend map sets too if these looks vastly better than Garmin's Topo.

This worked out better than I even hoped.

I added a NW Trails overlay to the topographical maps I downloaded and sent the works to the SD card in my 780.

Now I have 5 state topo map sets, the trails overlay and citynav to choose from.

I am definately going to try and produce a slimmer set for my Legend handheld. The free topographical maps I downloaded are a vast improvement over Garmin's TOPO in my view.

The NW Trails overlay looks like it could be a benefit...if nothing else to show me where all the mountain bikers may be so I can avoid them.

I'm going to have to try this too. I have national Park topos & I want to see if they work.

The NP TOPO set is also 1:24000 so it should be very nice on the nuvi.

I added all the National Park POI's to my custom POI file along with a bunch of other good stuff.

With these extra mapsets I noticed it seems to take the 780 a few seconds more to boot up.

I really want to get the 1:24k maps to my Legend though for trail walking.
