Where i can find my serial number on my kenwood dnx9140

You will have to pull the unit grab the serial number all kenwood and ask for the antitheft code

If you mean the security code:

You will need to visit an Authorized Dealer or service center for that product to get the unlock code reset. You can find a dealer listing on their website, or call them.

Probably not, you can buy security codes online, you just need the serial number off the head unit so you may need to get it out,

have a look here fore some head unit removal guides ;

www.carheadunit.co.uk

There is a software update you need to download from garmin.com to harddrive and then paste to a SD memory card and use to update the unit.
Hope it helps!!!

U have to have remote I just fix mine kenwood company was no help they want to charge when they could just tell u what to do but hit me up if u want to fix

21000522 is the serial no.

try going to a stereo store that sells kenwood and see if the can remove the code for you.

Sorry, there is nothing like that available on any car stereos I have ever repaired. I have been repairing many different aftermarket brands for over 17 years.

The Kenwood serial number is on the bottom of the stereo on a sticker along with the model number.

You can pull the radio very easy, take the face and the trim ring off. Then use something very slim and stiff that will fit between the radio and the cage that holds the radio, your radio should have come with 2 metal strips about 6 inches long that are used for pulling the radio. Push those metal strips in along the sides of the radio but inside the cage, and when they are in far enough you can pull the radio out of the cage that holds it. You can pull it out about a little over half way and see the serial number on the bottom.

I hope this helps you pull the radio a little easier, since there is no way to get the radio to display the serial number on the face.

hi, KDC-MP2028 is the model, what you need is the serial number printed on a tag at the back of the stereo
