Ive had the f700bt for about 3 years and have never updated until 2day when i screwed up and tried to update with the FX 3.1 update with mods i downloaded from here. went thru this full process:

1. Insert SD card into AVIC and turn it on.

2. When the pioneer logo comes up, press and hold the menu, map, eject and the reset buttons at the same time. When you hear a pop sound from your speakers, let go of the eject button but continue to hold menu, map, and eject buttons. This will bring you to a blue screen, telling you to reset the unit (ignore this), you will have to enter the service combination. Press the volume knob in this sequence and you will see * signs for each push: Up, Up, Down, Menu, Left, Right.

3. Select Wince Upgrade

4. Select Update SD Format

5. Wait until it says restart in the bottom center. Reset the unit and leave the SD card in.

6. You should be greeted with testmode (It will look very similar to normal windows). Open Explorer and copy the contents of the "My Flash Drive" Folder from the SD card to the "My Flash Drive" that is located on the unit. Overwrite everything. (It will the copying will take 140min but will only take about 20)

7. Press and hold reset for 5 seconds.

8. Select your language and voice options.

9. Enjoy FX3.1

 

Then realized i was supposed to update to at least the 2.8 firmware b4 trying the 3.0. i downloaded the 2.8 upgrade from the pioneer website and began installing it but when it got to the AP2/iGo part of the upgrade at 14% of the process it turn read and said copy error. ive checked the whole board and havent seen a similar problem but would great appreciate some help on what to do to fix this. Thanks in advance!!!! Sorry for the book!!
