I started by putting an 8 GB micro SD card into my new Garmin 450t. Then I went to GPS File Depot and downloaded: Garmin Training Center, Garmin MapSource, and Washington 24K Topo Map. Washington 24K Topo Map created file folder on my PC where it placed a large number of .img files which I could not open directly, nor could I open while in Map Source. Just guessing what to do next I copied and pasted the .img files directly to the SD card and tried to open them using the GPS device with the command series Setup>Map>Select Map but could not see any sign of the files. I could see on my PC that they did copy to the the card they just aren't visible to select from. When I tried to open the .img files in Map Source I get the error message that Washington Top/22029297.img is not a valid map source file.
I would be happy to erase all these files and start again if there is a better way.
Thanks for any ideas you might have.
