Customer Question

I have a Kenwood connected navigation system DNN991HD. I bought the vehicle it is in pre-owned. I'm needing to reset the unit to restore factory settings to put in my info. (The previous owners info in in the system & is password ***** The dealer contacted him but he doesn't remember his password)
When I push the "reset" button like the manual states, it doesn't do anything. Can you help me with this?

Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

Is the Kenwood device (and thank you for identifying the model #, that can be a great help...) prompting for a password ***** passcode, and doing and allowing nothing else?

Customer: replied 11 months ago.
Correct
Expert:  Russell H. replied 11 months ago.

It persists in prompting for a passcode, even after you press and hold down the RESET button for over 15 seconds continuously? try that.

If it still does after that, then try entering

0000

and then if that fails

00000

and let me know, please.

Customer: replied 11 months ago.
I tired all options. Reset button did nothing. Tried both 0000 & 00000 and received this message: password ***** ***** correct or service is not connected.

I've been using the guest user acct for months. Today it won't sign in to anything.
Expert:  Russell H. replied 11 months ago.

OK, thanks for the info.

I think the error, despite mentioning 'service' refers mostly to the wrong passcode.

To be tried also:

1111

or

11111

or

1234

or

12345

and see if any of them work.

Ok, brb
Customer: replied 11 months ago.
Nothing��
Customer: replied 11 months ago.
Any other ideas?
Expert:  Russell H. replied 11 months ago.

I'm sorry to hear that.

If the RESET button produces nothing, if the passcode prompt is always here regardless, if the default pass-codes don't work... let me research this for a minute or three...

Customer: replied 11 months ago.
Ok thank you
Expert:  Russell H. replied 11 months ago.

If you haven't tried this:

- press the RESET button.

- turn the device OFF after waiting for the count of at least 10 seconds.

- leave it OFF for at least 5 minutes or so.

- turn it On again ... do you get the Initial Setup screen, this way?

Customer: replied 11 months ago.
No, same log in screen came up.
Expert:  Russell H. replied 11 months ago.

Can you log in as GUEST, with any of the default passwords I have already had you try?

Customer: replied 11 months ago.
No that did not work either
Expert:  Russell H. replied 11 months ago.

Try GUEST only don't enter any password ***** does that work at least?

Customer: replied 11 months ago.
This is what comes up on guest. It won't do anything else
Expert:  Russell H. replied 11 months ago.

Have you tapped on the OK in that screen?

Customer: replied 11 months ago.
Does nothing. Frustrating, huh?
Expert:  Russell H. replied 11 months ago.

Well, no. That stands to reason if the Administrator and Guest passwords have been set, rather than being in the default (no-password) status.

I'm sorry to say there is no procedure for clearing the passwords or a reset of them, aside from what you have already tried.

An activation code for a car radio or car stereo etc., is an anti-theft feature. When the device is removed from the car, the battery power is interrupted to it, and this activates the anti-theft feature.

Sometimes this anti-theft feature is activated when no theft is involved, for instance:

- when a car stereo is sold, after being taken out of a car, by its legitimate owner.

- when a car's battery has been disconnected for servicing of various sorts or in the event of car battery failure.

The code is very hard to 'generate' or hard to find. It would not be an effective anti-theft deterrent otherwise. I have not the means to generate the code for you (though I believe it is generated from the serial # of the device and according to the maker and model.)

I advise that you take the car to a dealership for that brand, and have them generate and enter the code for your stereo.

I have Opted Out also, opening the case to any other Expert here that might have a better answer.
