To do this, you must transform them using the JNX2IMG software.

The issue there is that you are limited to how many img files you can have on your device..On my Oregon 650T I already have 18 Img files so am almost at my limit.... If I remember correctly you can have 500 jnx files and 250 custom(kmz) files possible other way round. JNX filses can be a lot larger then custom maps in area but it is at the cost of storage.... So would love a way to reduce the JNX file size....

I can confirm this is still working on the latest Oregon 650 firmware (5.60)
