Question about Kenwood DPX-440

1 Answer


Hello.... i have purchased a cd player on ebay for my car - a kenwood dpx 440 . The cd player works well as does the tape deck. The radio is causing me problems on the FM band. From the time i connected it the radio goes from 76.0 to 90.0 FM and then back to 76.0. I have changed the aerial and have tried pushing most buttons but i am unalbe to get any of the stations above those to frequencys. It picks up two staions between the two points. The AM works as normal. I think it came out of a imported vehicle although i am not 100%. Any suggestions would be much appreciated

How to input extra audio line for kenwood dpx-410

If it's got bluetooth, you can buy a little aux to bluetooth 3.0 off ebay.
If not it looks like a cassette tape adaptor is worth a shot.
If either one of those don't work fm transmitter is an option, I would stay away from those little ones you plug inot the 12v. Good ones can run you a 50+ and the work in some cars and not others. I would find one that Y's into the antanna at the back of the raido.

Thanks Robotek. Here is what worked for me- the differences is in how you enter...

Hi there, there is a standard procedure we use to bypass the code when we have the gear on the test bench for repair. Try this and it should sort out your problem

You need the remote control to do this, if you don't have one, then you may need to go to a KENWOOD agent and get them to clear the code for you, or purchase one for your use.


Your code number is 5227 (KCAR)

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

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

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

A FixYa rating would be fantastic for helping you out with this techo tip.:)
A FixYa vote is a great reward for the challenge of solving your problem

Kenwood dpx manual

I dunno if the manual will help you with not being able to tune the radio past 90.0 on the FM dial, but here is a link: I apologize for not being able to find a freebie copy. Is probably out there on the interwebs somewhere, but I can't find it today.

When electronics screw up like that, it is very likely they are simply shot. Broken. Munched. Kaboodled. History. Maybe use the $5 USD they want for that user manual to buy gas to drive to WalMart and buy a new one.

I would have thought that it should go from the amp to the tuner,then the tape deck and finally the CD deck.

I'm suspecting that your tuner is faulty and thats whats causing the system to shut down

Kenwood deck cd eject problem

Actually, yes! That could very well damage any unit without a protection mode. Unfortunately, in my long time experience in car audio, a deck that spits cd's out has a damaged or misaligned laser lens. This could be caused by driving to fast through pot holes, speedbumps, or going down train tracks. Find an electronics repair shop locally to see if having it repaired will out weigh a new deck. I found one new in box on ebay for $89 + shipping.
