Hi!
I had a Colorado 300 but it get broken (the USB-socket) and the Garmin support offered me the Oregon 450. There is one difference that bothers me:
I create my owm Maps with mkgmap with different layers like the All-In-One. On the Garmin device I have diefferent profiles for different purposes. In each profile different layers are activated.
When I copy a new img-file (same file-name, same IDs) to the Oregon, the device “forgets” the adjustments and displays all layers in all profiles.
Any idea how to fix it/work around this?
