What I am planning on doing is load data (waypoints,routes,tracks) state by state from Mapsource to an Micro SD card. Then when I enter another state delete data on the GPS to make room for the other data in the SD card. I am wanting to mainly navagate using tracks and 20 isnt enough for my trip. I have downloaded data to a SD card and loaded into a Zumo but it doesnt seem to want to let me on the 76 CSX. Any ideas?
You load the maps onto the SD card and tracks on to the unit directly. You can't delete portions of mapsets as they are all contained on one file. You can turn sections off from being displayed, but not sure what you would gain there. BTW, you can fit a whole CN NT mapset on one 4 Gig card which cost about $10.
So what your saying is that I cant load tracks onto an SD card and upload them to the 76CSX? The Waypoints arent a problem or the Routes. I just wanted to be able to load more Tracks off an SD card instead of carrying a lap top with me to load them from Mapsource.
All the SD card holds is the mapsets you load and the .GPX daily track log written to it (which the 76 cannot read until it has been manipulated in Mapsource). It's too bad that Garmin doesn't (or maybe can't) do an update to allow the 76 to access the SD card for more than the maps you load. So close and yet so far away.
Or learn how to load your many tracks as ACIVE LOG XXX files, and live with the limitations (all will be one color, DO NOT record tracks as you ride else you'll overwrite your prepared tracks, track names must be named ACTIVE LOG 001, ACTIVE LOG 002, up to ACTIVE LOG 999). This technique allows you as many tracks as you want (up to 999), as long as they don't add up to over 10,000 total points. I have had over 100 tracks loaded in my 76cx at one time. This is all done with the internal memory, not the SD card. So, you name your tracks as described above, load them ALL before you leave using MapSource, and you don't need to load anything later. Just MAKE SURE you have turned OFF track logging else you'll be screwed half way through your ride! There is a thread somewhere in here that explains how to do it. Or search the net for: GARMIN "ACTIVE LOG 001".
There is a track line displayed on the map between the end of ACTIVE LOG 001 and the beginning of ACTIVE LOG 002 and so on. Hopefully where the end of your actual track segment is and the start of the next one is obvious to the user and doesn't go over a huge ditch or canyon.
That doesn't happen unless you mess up when preparing the tracks. I've seen it before, but forgot what mistake causes it. I'm looking at my 76 with ACTIVE LOG files in it right now, and the tracks are not connected.
