Ok, I've read this and feel like a right numpty. I'd like to load these maps onto my GPS60CSX and give them a try but have no clue as to how to do it.
I have a USB lead for my Garmin and it has a 1gb card in it but plugged in to my PC I cannot see the Garmin.
Is there somewhere a truly simply 'words of one syllable' numpty special guide please?
On my 60CSx, I've just done the following......
turn on GPS
[menu] -> use with GPS off [enter] (just to avoid logging rubbish positions)
[menu] [menu] -> Setup [enter] -> Interface [enter]
-> USB Mass Storage [enter]
long beep and GPS goes dead, but with lit screen
connect USB cable
chime from PC
A Windows Explorer window pops up showing drive G: with a "garmin" folder on it (drive letter may vary)
In the system tray (bottom right, with the clock) there's a new icon showing a little grey something with a green left-pointing arrow above. Holding the mouse pointer over it shows "Safely remove hardware"
The G:\garmin folder has in it a file called "gmapsupp.img" This is my mapping.
There is also a folder "Poi" that contains the custom points of interest I loaded using the Garmin Poiloader program (free download).
Tracks logged to the card whilst riding will show at top level on G: - eg G:\20090219.gpx
The gmapsupp.img file I use was created by Mapsource from City Navigator data. OpenStreetMap data will have to be digested into a file of the same name as talked about up thread, and just copied into G:\garmin\gmapsupp.img using Windows Explorer. Create the "garmin" folder if it's not already there.
To disconnect the GPS, click on the "Safely remove hardware" system tray icon and select "Safely remove USB mass storage device - Drive (G:)"
You'll get a message on the PC saying you can unplug, the GPS will beep, and it will return to the screen it was on before you went into the menu to connect.
If you unplug the cable you'll get a GPS beep and a message "External power lost - turning off in 30 seconds"
If you unplug the GPS without doing the "Safely Remove Hardware" bit, you will probably have to turn it off to get it working again. You may also find that not everything you copied onto it is there as the "Safely remove hardware" function also flushes the write buffers.
