Kenwood navigation system not working after car battery dies

I have the kenwood navigation system in my 2002 honda crv. yesterday, i accidently left the lights on and ran the battery down. i had left them on for about an hour and a half, then jump started the car and ran it again. prior to that the navigation system worked perfectly in every way. since the battery was run down, it now doesn't display properly. audio passes through it ok, but the display is unusably dim and unreadable. i've run the car last night and today, it works fine and the battery seems to be doing fine. however, the kenwood system still has the display problem. is there something i can do to get this working again. i expected to perhaps lose my radio station presets, but don't understand how the display is still effected. did jump starting the car hurt it somehow? any ideas as to what about that situation would have effected the display?

I have seen problems in the hideaway (brain) where 8v reg circuit fails causing higher voltage(12v to 14v) to be on that 8v line. First component to fail is the Tuner followed by electronic volume ic. I have probably seen 6-8 failures where tuner fails. Fix is to replace tuner and replace open chip resistor in Hideaway box to restore 8v regulator to proper voltage.

I would be willing to bet you have a 8v regulator circuit failure in hideaway Box. I have seen many of these units where a resistor opens and causes 12v instead of 8v to appear at tuner and a few other IC's. Usually But not always destroys tuner. if there are questions

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.

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,

SOURCE: Kenwood KVT-815DVD Unit only buzzes

I bought a Kenwood KVT-815dvd player and got everything hooked up to only find out that it had a security code. The problem now is that I got it from a pawn store and they did not even know that it had a security code on it. So is their a way I can bypass they password or just reset the whole unit so that it does not have one. Also, where is the memory for this unit?
Thank you

The unit has power but the screen is blank and nothing is playing.

Get use to it...this is a common problem with the Kenwoods. Just use a paperclip to hit the reset button in the bottom left of the unit.

I have an issue.. my battery died yesterday the guy who jumped my car messed up and attached the jumper cables wrong on his battery. Now my kenwood excelon ddx 7015 wont turn on at all do you think it is...

Hello Melissa,

The first thing I would check is if your fuse is okay. If your fuse is blown replace and try to turn on the radio. If the fuse is good have the radio taken out and have it bench tested. take the power wire and the memory wire put them together and apply power to them then take the black wire and connect it to ground if the radio turns on then its okay and he fried something else. If the radio doesn't turn on then chances are that he fried it.

You can use a car battery to test your radio or a portable boost jumper.

Hope this helps you.

Navigation sound

If all of the other speakers work properly, it is because that is the way you have it configured. Go into setup and change the configuration. For instance, the bluetooth phone speaker is set up for the right front speaker by default so as to not get a feedback loop with the microphone.

Kenwood DDx8017 with navigation

Which NAV system are you using with it? KNA-G510, etc needs to be plugged into the NAV port on back and then you need to go into the System Settings to enable the NAV option and voice interruptions correctly. You'll want to look for AV Interface in the System Settings.

Here is the DDX8017 manual for some help:
