The system will work ok until you turn ignision off and then on and then nothing from it for will not turn on . it will then come on asking for code? i put the code in and its ok again until i turn off...


Sounds to me that your constant wire is not connected.
If you had it installed I would take it back and have them check this wire. If you or a buddy hooked it up then remove the deck and you will see this wire on the back of the deck within the harness. If there is not a direct hookup to the factory harness then you can piggyback on the red (Bat +) power wire.
The purpose of this little wire is to keep a very small amount of power fed to the head unit for memory purposes.

I have 1997 Chevy Blazer with a a Delco AM/FM/CD player with theft lock. The radio plays but the CD player codes ERR, then ejects the CD. Is this a theft lock problem...I bought the truck used and there is...


The err message has nothing th do with theft lock. More than likely the laser assembly is bad. You are probably better off replacing the deck with an aftermarket one.

I got a new car & the set only works for a few sec. then restarts all over can u help set # cn-hds700td


if you're not located in Japan with that deck, it will stop responding. i have the same deck in a imported car from japan, and i found out it freezes when it has a gps fix. resolving this issue is to either cover the gps antenna with tin foil, or disconnect the gps cable from the back of the deck

I cant connect a 10 amp noise supressor


you connect pair of rca to you car deck and the other pair to your amp inputs, this just acts like a bridge to filter out noise between deck and amp

Asking for codehow do i get past that


you cannot get by it. You either need the security code that was set when the deck was new or you may be able to send it to kenwood for reprogramming but i doubt it. not much yiu can realy do about it.

How do i wire 6x9 from the back shelf to the head unit using new wire where do i wire it on the head unit?


if you are going to place the speackers into the rear shelf than you can run your wires along the underside of the shelf,then towards the back of the rear seat, then run it down the length of the seat, when you reach the bottom you will need to try to pry the backrest portion seat foward just enought to get the wire thru to the front, then you will need to get either a phillip or slotted screwdriver, open the back door and at the bottom unscrew the trim from the bottom of the door way,run wire thru do the same with the front door, then run wire behind the trim around or near where the emergency release handle is at, run wire behind instrument panel towared your deck. when you go to wiring up the deck and speakers check on the deck to see if it has a wiring diagram on it if not: most decks come as follows ( white wires front right ,blue or purple rearl left, brown front left, grey rear right red is + black is - yellow is constant +( always on so your deck is able to stay programedwith your presets and audio settings and clock)one single blue or purple wire is the remote for your ampif the colors dont match the ones on your deck then hook up your deck to the power only when the deck comes on go ahead and set your speackers to only the rear right speacker and take your wires from your speacker and touch them to the wires on the back of the deck, once you hear the audio coming thru go ahead and mark this as right rear or rr then using the same speaker change the settings to rear left speacker and do the same as with the other one mark it rl and do same for front speackers

I have a kenwood deck and it locked i can not use it it is a kdc-mpv6022


Good Day,

KENWOOD SECURITY CODE CLEAR procedure

These codes are applicable for all Kenwood radios that do not have DVD or DVD screens located on unit.


Your radio will require one of the following procedures.

Type 1
During the code request mode, while holding the DISP key depressed, press and hold the Volume UP or DOWN key for 3 seconds

(so that “…” disappears).
Then using your remote enter your code.

Type 2
Press the "Auto" button and "Track up" on face of radio at the same time. The four dash lines ( . . . . ) should "disappear".

Then using your remote enter your code.

Type 3
Model# DPX-4020 and DPX-4030
Press and hold the 1 then the 6 preset key (preset keys are the buttons on face of radio for storing you "favorite" radio

stations). "C" should display.
Then using your remote, enter your code.


Enter your number from the remote control unit. Your code number is 5227 (KCAR)

* Press numeric key “5” ( 2 times ) and press the Track UP/Next Track key on the remote
* Press numeric key “2” ( 3 times ) and press the Track UP/Next Track key on the remote
* Press numeric key “2” ( 1 time ) and press the Track UP/Next Track key on the remote
* Press numeric key “7” ( 2 times ) and press the Track UP/Next Track key on the remote

The security is canceled and the set enters the TUNER mode!

The above was pulled from:
http://forum.ecoustics.com/bbs/messages/4/134366.html

Also try:

press reset use remote right after it loads press 552222777 then track forward do this with the remote open so you can use the numbers and make sure its in the audio mode the little switch on the side. prerty simple p.s. nothing will happen on the screen so dont stop pressing the code and press track forward you can now set the code to what ever 4 dig code you want in the set up screen

Also try: bypasse code of "2222"

Hope this helps
