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)

Oregon 7xx_4.70 tested and it is OK for jnx with patcher 380 !
Thank you Alex !

Hi all;

I have some jnx maps. When I send them to the device and turn on the device, I get an invalid jnx file warning. I patch and install firmware with "JNX Patcher". At that time I get a radio disable error. How to install JNX files without error.

my device is alpha 50

Hello!
You have to use two pathes. You have to take an original gcd-firmware from garmin site. First use the "gnx-pacther". Then at once you need patch this one by second patcher for "radio disabled". Then update Alpha this firmware.

I know this, what I pointed out that the project seems to have been abandoned by the author, and does not even seem to write on the FORUM anymore.
