How do you enter test mode with the F700BT, I can't find it anywhere.

I hold down reset+eject for 5 seconds and it just reboots. Where's test mode.

Im having the dreaded ezrider fatal application error.

testmode is when you load an SD card with the appropriate files so you can get into windows ce desktop. Do a search for testmode. There are different versions of testmode (it depends on what version of the firmware you have on your AVIC unit).
