i have the F700BT radio and it works good for like 10 mins and then the touch screen starts to act up. it doesn't respond to my touch with my finger or my stylus. if anyone can help me Plz. maybe it needs a hard reset?

Have you tried calibrating the screen?

yea i tried to calibrate and it doesnt work. some times i get stuck in the calibration screen

To rule out software, try starting it up in the testmode and see if it still does the same thing.

But it sounds like its hardware, your touch screen is going, going, and it will soon be gone.

Give pioneer a call and ask for an rma number and hope you have a spare stock head unit or something else to use for the mean time.

it seems to happen when i put the heat on in my car

Do you have a steering wheel controller connected?

I could not use the touchscreen after I moved the volume, it was the steering wheel controller causing it.

i have a steering wheel control but it is not connected
