Hi Everyone,

I got my hands on a Kenwood DNX7000EX which as far as I know is the same as the DNX7140. I inherited it from a friend who did something weird to it when trying to update the maps on the navi and now the navigation displays a black blinking screen as if it's restarting every few seconds. Connecting to the computer through the micro USB port makes the device show up for about 1 second before it reboots and disappears. This behavior loops forever.

I'm going to take the device apart and attempt to put the device into preboot mode by soldering two wires onto the navi pcb board. I've read through a few other threads as to the steps that this will involve and am confident I can do it (I'm comfortable with fixing electronics and soldering). My question is which GarminCure3 version do I use? For example, in another thread, someone was told to use "GarminCure3 for dnx7x20_dnx8x20_270 with Updater_exe" for a DNX7220 device which makes sense. I also found a thread for a DNX9260. Is there a specific version that exists for a DNX7X40?

I do have a backup of all of the original files to put back onto the device after reflashing the firmware.

Thanks in advance!
