I haven't done any hacking or modding on my deck. I got in the car after doing some grocery shopping and all of a sudden the map, menus, and some of the menu graphics on the radio presets screen were gone. I then got home, turned off the car and started it back up, everything came back, or so I thought. I can no longer find or pick a destination nor does my map display street names, also in the settings I can't access Nav Settings or System Settings.
I quickly downloaded the latest firmware and went to update but the system doesn't read the SD card at all, it just boots up like normal.
