Hello again:
I want to comment on my new experiences. I have had the opportunity to patch an Etrex 30x and an Etrex 32x and I have not had any problem. I downloaded the original firmware from Perry's page and applied the two programs to unlock the JNX (UNIVERSAL FIRMWARE PACHER 380) and the City Navigator NTU (IMGPATCHER 220 latest version January 2020) to the downloaded firmware, no matter the order, and everything worked perfectly. NT Maps do not need to unlock GPS, only the map with GIMGUNLOCK v.0.04.
I believe my first Etrex 32x unit was defective.
I have also concluded that the Etrex 32x, having an 8 Gb internal memory full of Garmin maps, cannot handle new large maps. If you want to add your own maps you have to remove some of Garmin. I have also verified that the maps can be deleted and reinstalled without problem or the maps can be transferred to the microSD.
