I just picked up a GPSMAP 76cx, and installed the 2011 city navigator onto the SD card. If I want to put other maps on there (such as a TOPO of Ontario), do I need to put it on a separate card, or can both maps reside on the same card?
Also, do tracks take up lots of card space? I want the tracks to save to my SD card, but I am not sure if they are space hogs or not.
Thanks for any help you can give me.
