I'm not sure if this will reset it, but in the front of your navi system there is a tiny hole (below the volume control knob). It'd probably be best to use the end of a paper clip or the tip of the pen, but you could just click that and it should reset the system. If anything, the code should be 0000, at least my default code was that. Hope this helps!

Q: How do I reset my security code?

A: If you do not know the security code for your unit, you will need to take the unit to a Kenwood authorized service center to have it decoded. The code feature can only be activated when the code has been entered twice, so it isn't accidentally activated. The service center will often require you to provide a proof of purchase as this feature is designed for theft prevention and the proof of purchase will ensure you are the rightful owner of the product.

Hello please please help me I gave my car a boost and now it says on my deck it needs a 4 digit password but I never set up a password I don't know what to do please help car is in a shop and...

In-car electronics commonly use this sort of password/code protection, to make it more difficult to use or sell a unit that has been stolen from a car. It is triggered when the unit is disconnected from the battery (or, in your case, when the battery goes flat/dead).

According to the Owner's Manual, this system has a user-defined password, and the security is not enabled by default. If you didn't set a password, perhaps the installer did it for you. Check your install receipts/records, or have them check their records.

If you bought the car second-hand, with the unit preinstalled, you may be out of luck unless you can get the code from the previous owner. Since the password isn't pre-defined, the manufacturer really has no way to help you with this. Your only other option is to try the 10,000 possible 4-digit codes until you find the right one.

It says disk error with any cd or dvd. The player worked with no problems till my wife tried to update the unit's software.

You will probobly need to reset the unit. In the manual there will be instructions as to how to do that. The other option is to Re-Try the firmware update and see if that helps, sometimes you can get a corrupted download,, it just happens..

The detailed maps are "locked" all of a sudden!

If this is still happening then go to Kenwood direct, they supplied the unit with the pre loaded software and therefore they should deal with the problem as they are not supposed to lock the software. Kenwood if need be will contact Garmin for you. You may find that they have experienced this problem with other users too.
