Hello – I just purchased the Oregon 450T. I also purchased an external 8G micro SD memory card and the Topo 24K DVD for the Northeast. I manually copied all of the files on the DVD onto the external memory card; however, I cannot get the GPS to recognize any of the files on the external memory card. Nevertheless, I transferred some of the 24K data (Connecticut and Rhode Island) via BaseCamp into internal memory and it works fine. How can I get the Oregon 450T to access the entire 24K Northeast topo map on the external memory card?
Thanks Sussamb. I'll give this a try. I started doing that but the file transfer was going to take over 2-1/2 hours so I stopped and did a direct file transfer.
It worked! :cool: To cut the transfer time, I plugged the micro SD card directly into my laptop, started BaseCamp, BaseCamp started MapSource to create the image file. Total time around 1 hour 45 minutes. Placed the micro SD in the 450T turned it on - and now I'm one happy camper. Thanks again Sussamb. :)
