You got my pm
I bought a brand new 2015 Garmin Nuvi 57LM. I have also purchased a Garmin Map of Israel off of Ebay. Once I received the sd card, I inserted it into the unit and it came back with two errors. The first one was "cannot unlock maps" and the second one read "corrupt maps". I would really appreciate it if somebody can help me load up the maps from the sd card onto the GPS.
From reading some of the threads, I understand that I have the newest one which doesn't allow "unlocked" maps to be displayed. If you can help me, please let me know by replying to the thread or PMing me. Thanks in advance.

Since I am only seeking my device to read the unlocked maps on the sd card, I am thinking that I only need to reverse the firmware on my device. So I only need to follow the steps under " how to reverse back your device to a previous fw". I have looked inside the folder "Garmin" on the GPS and I found only two XML documents; DeviceConfig_2DFootprints_Enabled and GarminDevice. I looked through the latter and found that the software version is 230. I also didn't see the gupdate.gcd inside the Garmin folder. I only have the two XML documents. Thanks again.
