i have been using a stylus and a penn cap but it it still wont let me clock on the bottom 1/4 or top 1/4 of the screen........ any other thoughts?

I tiered to re calibrate it in the control panel, but all it lets me re cal is how fast to double click. I even tried to hook a mouse up to the usb cable but even that was a no go.Ill keep messing with it but could use some more help. Is there a more up to date test mode out there besides 2.3?

I recently upgraded my unit with the FX3.1 firmware following all of these instructions 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 your screen goes completely blank, let go of the reset 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,

I am having the same problem with my Avic unit as well. How were you able to click on the start button?
