Edge Explore 1000

Hi.

Since I couldnt find any forum for Edge Explore 1000 I will ask here.

Due to some issues whith sound and other I decided to downgrade my soft/firmware to 8.1 (stupid me) and thats when the real problem began.

It cant find my installed maps even if I reinstall them via GE.

I tried to update it to the latest firmware via GE, but GE just says its up to date and place a new GUPDATE.GCD but when i reboot my Garmin it still says it 8.1 and still no maps.

I tried to download the 9.3 firmware and put inside the garmin map, but still the same thing, Ive also tried to downgrade lower than 8.1.

Ive tried every reset I can find and Ive tried to format the drive but still the same thing.

Its like its branded 8.1 now and no mather what I do it stays like that and dont read my maps.

Is there any other way to flash it or something else.

Cheer

Anders
