Thread: Is this nuvi 2589 simply Bricked or is it a Hardware Failure?

Beautifully explained, Butters. (And I'm sure I've seen similar/exact same before but I couldn't have pulled it together without handholding.)

Two questions.

1. My smallest microSD card is 16GB SDHC. If this card is contraindicated, I'll buy a tiny card and report back after I've tried it.

2. I don't think I can put my nuvi 2589 in a stable power-down state; it powers right back up every time. Can you suggest a sequence? Here's my guess:
a. Starting with the instrument in hung state;
b. Open 194701000880.rgn (patched boot.bin only) in Updater.exe, select "USB Device" and hover on OK button;
c. Connect USB cable;
d. insert microSD;
e. Position thumb ready to touch G;
f. Press and hold Power button until screen goes blank;
g. The instant the Garmin logo reappears, touch and hold G;
h. The instant the device appears in Updater, click OK;

Do I need another power cycle to execute the new boot.bin and in turn, the region bins in the SD card?

If you believe the "hung" device is waiting to mangle the SD card as soon as it sees it, what can I do? That "device available" window is literally just a few seconds - if I insert the card then, I'll have no chance to start Updater. Wish I had an assistant... or four hands.
