Re: Map source help
I was pretty sure you'd get the right answer after a while, and of course you have, but not with much explaination.<br /><br />Remember how when you started loading in maps (you have a GPSMap-76S, right?) and when you did it erased your built in waterways and markers or whatever it is that they call their baseline on water stuff? Well, loading in from Mapsource does pretty much the same thing. If you pull from one disk and load it in the first thing that the loading process does is note the existing memory for over writing, for all practicle purposes erasing it. So then the new map resides in the GPS' memory. The problem is that if you go to a second disk for additional maps, even though there is plenty of room left in memory to hold additional maps segments, what it will do is erase everything that is currently in there before loading in the next map.<br /><br />So what you have to do is find a way to move the map segments from the disk(s) to some temporary holding folder until you have the stack of them you want and then moving that entire block into the GPS at one time. I have not found a way to do it, but I haven't tried very hard.<br /><br />The reason I wanted to do it is that I use MapSource Roads&Recreation in my Map-76 all the time just for the street maps. I also have the BlueChart disk of the water borne stuff but it only gets used in the computer. I can not put on street maps and nautical charts at the same time, even though both come from MapSource disks (a lot of folks forget that the Bluecharts are just a subset of the MapSource system). <br /><br />I only use the 76 as backup on the boat anyway so there's no reason to have nautical charts on it. I've got them on the chartplotter, which uses a BlueChart data cassette, so I really don't have any reason to have them on the hand held. If the big box breaks down the little one would just be used for the ride home anyway, and its not like there's a lot of fixed objects to hit out there.<br /><br />Thom
