helpful to others posting.
I have just bought my etrex Legend CX so getting used to it. I tried to
download the SMC contour maps to my unit using Mapsource, but the
Mapsource software cannot even find my GPS ! ( I tried downloading the
latest USB drivers , but nothing helps)
What version of Mapsource? Did you install the USB drivers before
connecting the eTrex for the first time? (I vaguely recall that is
needed). if it's a USB driver problem, other programs should have
trouble too - try Oziexplorer, or similar (one of the two free demo's
can interface to Garmin GPS) and see if you can read/write tracks or
waypoints or whatever.
Quoted message said:I then resorted to the Send map utility, which appears to just wipe the
existing maps off my GPS, and then I can't even see any of the ones it
is supposed to have transferred.
Putting a new map on the unit always wipes the previous ones. there was
a 'Sendmap' attempt to fix this but I think it's hopeless. For one thing
I believe there is a global POI index built on the PC for all the maps
in the set .. the GPS probably isn't smart enough to add a new map in
itself.
Quoted message said:( I had copies of my basemap and replaced it luckily)
How did you replace it (i.e. what did you use to send the replacement to
the unit)? The basemap should actually survive anything you can
reasonably do using a PC.
Quoted message said:This is all most likely due to the fact that I am not familliar with
any of this software or hardware and cannot follow what seems simple
enough instructions from the SMC site.
Does anyone have a blow for blow instructions on what setting the etrex
Legend CX GPS needs to have , and how to transfer the maps using
SENDMAP or Mapsource (assuming I can ever get Mapsource to recognise
my GPS)
That's the first and crucial problem. Try google. Try reading the FAQ on
the Garmin website (www.garmin.com) .. if that fails email Garmin
support (they are usually helpful, or at least try to be).

tried to get this working, but must be missing something crucial.
This is one of those things that's pretty hard to solve remotely. I
assume you do have the GPS set up to communicate using Garmin protocol,
(there are maybe some other options).
Step 1 - get =something= on the PC to be able to see the device, and
upload/download things (waypoints would be easy)
Step 2 - get mapsource to do same with waypoint or whatever.
Step 3 - get mapsource to send maps.
Apart from anything else if your PC can't see the unit, you won't be
able to upgrade the firmware.
