Driving home from work and I ran out of gas, opps. Tow truck brought gas car radio was working fine, I got home next morning went to take kiddos to school, Avh-4100nex prompted me for password. Odd I thought to myself the radio was never disconnect and car battery is good. I put in the password, however when I go to hit enter the button icon is unresponsive as the delete button is in turn selected. I next used a toothpick as it is not as fat as my finger to select the enter icon. Once again the back space icon is selected instead. In fact the entire keyboard bottom row of "key icons" of the touch screen are responding as if it was the row above.
