Do you happen to have the patched firmware for a Garmin dezl 770LM? I tried installing the patched firmware I found earlier in the thread for the same device with the same hardware version, but I'm still unable to load maps. I get a message saying the map is corrupt. When the patched firmware was installing, a message showed up saying that the firmware I was trying to install was older than the one on the device and all the user data would be erased. I pressed OK or Yes and it looked like it worked, but I still have the same firmware as before the patch showing up, so I don't think it worked. Thanks in advance.
