GARMIN GPSMAP 60CX MAPPING
~ Captain Paul's response to: ~ Pale Rider ~
Fantastic unit isnít it? You will find that the more you use the unit the more you will be able to use it more proficiently.
First the easy part of your question. Waypoints are stored as part of the internal memory of the unit.
The Garmin GPS Map 60Cx can hold up to 1000 user waypoints. These waypoints appear, if selected by the user (see page 44 of the owners manual to turn OFF this option), as layers on the maps that are currently being viewed in the unit.
However, I suggest that you NOT store that many waypoints in the unit. I prefer to keep the amount of waypoints at a more manageable level. Why have your Mississippi waypoints routes and tracks stored in the unit when hunting in Louisiana. Why have to scroll through nearly 1000 waypoints to find one that you want for the present area.
By using the data programs by Garmin, such as their Trip and Waypoint Manager or their free download of Base Camp, or their MapSource mapping program, you can have the waypoints arranged by different areas, and load only those when you are visiting that particular area. This is the electronic downloading-saving is the basis of the CAPTAIN PAULíS FISHING EDGE OF GPS WAYPOINTS. It allows you the advantage of having only the pertinent waypoints available for your use.
That way you can even have similar named waypoints such as CAMP, STAND or TRUCK in both areas and no be confused.
Concerning the memory card, check out page 58 in your Owners Manual for details on how to view the items on the memory card.
Usually putting one set of maps onto a memory card OVERWRITES the current data on the card. There is a way to side step this overwrite, by naming the file by a different name, but generally speaking the maps on the card will be replaced by the new maps you are writing to the card. This is why you donít have the earlier set of maps when you view the map options after installing the new maps of an area. When loading maps onto the memory card, download all of the maps you want at one session, during one download.
Garmin usually supplies a Micro Secure Digital memory card in 64mb size. In todays world, this is a relative small size for such a card.
Using a 2GB Micro SD card should allow you to store over 30 times the amount of mapping images than the current 64MB card that comes with the unit. One 2GB or certainly a 4GB card would allow you to easily store most if not all of the topo type maps you may need for both Louisiana and Mississippi. This is of course that the total memory of the maps of both areas do NOT exceed the capacity of the memory card.
Two or more cards for the different areas you are using the unit in, I believe, would be the better way to go as it would not interfere with the loading of both areas onto one memory card.
