Hello,

I had the case with W910R following an upgrade, when collecting data on the device and then let the SD card to the radio.
New use updates Alpine, before you had to update and remove the SD card for use.
Result, return to after-sale warranty, no way to restart iGO.
They changed an electronic card inside information after!
The original Alpine software is sensitive to the slightest mishandling!
Not easy to repair yourself.
