I'm having some problems with my Kenwood DNX7100. It turns on fine, but the touchscreen is unresponsive and so are the front buttons. The only exception is the Eject button: nothing happens if I do a short press, but if I hold it a little longer, the screen goes all the way down to the SD slot.
I'm electrically inclined so you can be as technical as you need to, I just don't know where to start on this problem. Can Anyone help? Thanks!

Had the same thing happen to me. All you have to do is use a pen or a paper clip and push the reset button located on the front of the unit. It cleared right up.

ground the green emergency brake wire just hook it into the radio ground and that will fix it

It sounds like either your GPS plug came out of the back of the unit, or your gps does not have a clear view of the sky, or if the gps is mounted on a trunk that opens and closes a lot the wire can break inside. I dont think the software is your issue, just to make sure if you update make sure the update file is the only file on the card, if there are other files (left over pictures, etc) they can cause the unit to disreguard the whole card.

Hello johnnychi925,
The unit appears to have been installed on the 12vdc connection that is on the same circuit as the the vehicle's ignition switch. This means that when the ignition is turned there is a rapid drop in voltage which cause the problem with your device. You need to connect the device to a 12vdc circuit that comes straight from the battery and does not connect to the ignition circuit. Now for another possible cause if the 12vdc you are connected to is from the battery and not the ignition connection. The battery could be dropping below 12vdc during the starting of your vehicle. This could be the sign of a malfunctioning battery, or a problem with the car's electrical system.
To test out if the battery ids dropping below 12vdc I would suggest connecting a voltmeter to the - and + of the battery and starting the car. The voltage should drop but not below 12vdc.
I hope this helps,
Thank you,
