Ok,

I hope this makes sense:

My unit is a Garmin GPSmap60csx

What I currently do:

I have the lakemaster MN chip for my unit. I have the arch harris file that I use for my portages and campsites. However the GPS unit can only hold 1000 waypoints.

I have the MNtopo11 from the file depot loaded into Mapsource and I overlay the waypoint file on top of that.

I then delete out the waypoints for areas I am not going near till it's below the 1k thresh hold.

What I want to do:

I have a 2gb micro sd card. I want to be able to put all the data from the mntopo11 map with all the waypoints on to the SD card and have the GPS read it just like it would the Lakemaster chip.

I have been able to get some of it over, it keeps telling me "waypoint memory full" So I believe that it's putting the maps on the SD and the waypoints into the internal memory not the SD card.



Has anyone been able to do this?

I've been wrong once before, but I believe that for the unit to use the waypoint - even if saved to a card - it needs to move it to internal memory before it can work with it. Seems like users have wondered about this for many years, reflected in message board posts all over the place.

When I run up against the upper limit on my 62st, I make a folder in BaseCamp on my iMac, copy data there, then delete them from the unit. It's not ideal, but I'll often do this with one trip area's points and tracks prior to copying the next trip area's data to the gps. Sounds something like what you are doing already, only using MapSource.

Yea,

Pretty much what I have been finding my self, your limited by the internal memory. Would just be nice to be able to load them all in one shot.
