Question about Kenwood DNX7100 Car Video Player

DNX7100 Security Code Password

Unistalled the  unit out of my old vehicle and installed into my new car. Of course when power is lost it goes into anti theft mode. Well when I typed in my original password the unit is still locked out. I tried several times. Also 0000,1111,1234, and the Kenwood 3051. I called Kenwood and faxed  them my receipt of ownership and they told me to type KCAR, but their instructions on typing KCAR in the unit was confusing and cannot figure out. Anyone have any ideas?

    I purchased a DNX7100 from a flea market, and I thought I was purchasing a new unit, but when I got home I realized it was used. I went back to the flea market the following weekend and the guy wasn't there. Now I have a unit that I can't use because i don't have a password. Do anyone now how i can reset the passcode? Please help!

While code request mode,point the remote control to the unit and enter this code 55222277or 552222777(depending the remote contro you are using)(try to press the numbers that faster you can) that is way you type KCAR from the remote control.
you will not see any change on the screen while you entering the number,only when you enter the last number the unit will go to standby mode.
if you make a mistake,reset the unit and start all over again.

let me know if works
thank you

    I have a Kenwood DPX-8070MJ Radio in my car. The battery on my car was changed and the radio was now requesting a Security code ( CODE****). I tried all tricks but in vain. Eventually i managed to unlock it.

    Here are the steps of unlocking a DPX-8070MJ radio player:

    (1) Press and hold the 1 and then the 6 preset key. There are 6 preset keys or buttons on the face my radio on the left side. The radio will display a "C" just after the "CODE****"

    (2) You now need to enter the code "KCAR" using a Kenwood remote control (The remote control for my radio is RC-600J). Point your remote towards the radio

    (3) Press Numeric Key "1" until the letter 'K' is displayed

    (4) Press Numeric Key "2" until the letter 'C' is displayed

    (5) Press Numeric Key "3" until the letter 'A' is displayed

    (6) Press Numeric Key "4" until the letter 'R' is displayed

    (7) Press "Ent" button on your radio and YOUR RADIO WILL BE WORKING AGAIN

    Deck was brand new when it was installed in 2002. Emanuel..I took your advice and pit in 55222277 with the remote, not good. The deck cycled and shut off. I turned it back in and put the screen back in. Tried to start over but to my surprise the screen would not come back out. I hit the reset button to try and start over and nothing, it just keeps cutting off. Prior to posting on this site I did call Kenwood, they told me to go to an authorized dealer, I went to two they told me about here in St. Paul Mn. Mach 1 and best buy, they both told me to call Kenwood. Oh boy...any suggestions...

You call Kenwood, and get the info for the closest national service center, they will tell you how much ($45 for me plus S&H), you ship the whole unit to them, and they send it back unlocked. Major bummer for me, I bought my car used, didn't get the code. I understand the need for security, but all this process does is shift some of the profit away from theives and back into Kenwood's pocket.

My ripspeed incar dvd player has got no picture but has got the sound what can i do to make this work

First thing comes to mind is a possible update to the system. Have you had it for a while now? If so, you should go to the computer and go the maker of the unit. Check under software updates or downloads to see if there has been a remedy or fix that the maker has published, if so...then do as it says to do and see if this resolves the problem before you get into the actual technicals of the unit. It may need nothing more. I hope this helps.

Fm works, am does not

Check the antenna connection. A poor connection will often be good enough for FM but make AM reception so bad the the radios auto-gain circuits will mute the output unlike old AMs that would just produce loud static in poor signal conditions.

DVD won't place discs

Did that just begin out of nowhere? IS the Dvd spinning, if you listen closely and the player is making noise as well? That would be the lens trying to get a read on it but if it's scratched (I'm sure you tried others) sometimes the lens just go bad out of nowhere...Mu original 500 Sony PS1 in 1998 lost its lens about 3 months in...I can't think of anything else right this moment....I hope you fix it...
