@sbihue,

Sorry to hear you bricked your Garmin.

But I have one question and I read this all the time about user's wanting to format their SD card and do just what you did.

Why didn't you just take the SD card out and format it on your PC or laptop.

I always remove my SD card to change maps or all POI's or replace it.
I keep 3 or 4 SD cards with different maps on them so when I am traveling I just pop in that countries map and drive around with it.

I also have one SD card with all of Europe on it.

But never format the SD card while it is still in the Garmin Unit.

But I hope you can unbrick the Garmin.
