My custom map is functional on the Oregon 400t. But then after using BaseCamp 4.2.3 with my Oregon attached, quitting and ejecting, the next time I try start the Oregon, I get the error message: custom map file is too big and will not show.
Then I have to reattach the Oregon to the computer, and manually copy my original custom map file (kmz saved in a different directory) to the Oregon. Then there is no error message, and the map shows correctly, and continues to do so as long as I don't use BaseCamp again.
I suspect that when BaseCamp quits, it saves a slightly different version of my custom map to the Oregon, which is then not readable.
The odd thing is that my own (manually copied) version of the file is larger than the one that BaseCamp saves on the Oregon.
Mac OS X 10.8
Can anyone tell me what is going on here, and how I can make BaseCamp stop doing this?
Thanks.
