Just last week I had a 930BT installed in my truck(06 Dodge Ram). I checked the firmware, and it looks like it hasn't been updated yet. per the instructions, I downloaded the file, decompressed it, and put the whole folder on a blank micro SD card. I put the card in the Head Unit, and restarted it several times. It seems that the update still hasn't been installed. Does anyone know what I'm doing wrong?
