I have had that problem with my pioneer avh8400 bh. all i had to do was turn the car off then back on. Has happened a few times, not for a while tho.

Maybe you need to disconnect the power from it. Maybe try taking off the battery terminal for a min then re connect. Might reset it?

ill try that, its been more than a week now that it does that. sometimes it works properly for a minute then back to being unresponsive again. some buttons in the touchscreen works all the time tho, so i dont know lol but thanks man!
