Question about Kenwood Sirius KDC-MP522 CD Player

1 Answer

Swapped out players and new one doesnt power up

I had a aftermarket pioneer cassette deck in my 04' chevy silverado, and I was given a slighty used Kenwood KDC-MP522 by a friend, which worked fine when he removed it from his vehicle. I pulled out the a cassette, unplugged it, and plugged in the kenwood, the door alarm beeped, and i could hear the cd player mechanically moving inside, then I checked to see if it would power up, so I turned the key to battery, but not the car on. Nothing, the deck has power and will try and eject a disk if promted, but no lights display...just a faint crackling on the door beeper in the dash... Im very confused because no fuse are burnt and the swap was basicaly seemless....I just used the exsiting aftermarket harness from the first player becuase the two were a match as far as hook-ups... any ideas?

    Well what i cant figure out, isnt the harness car specific, not reciever? what i figured would happen, and i could be mistaken is I'd go the store and they'ed sell me the same harness that the first player allready installed used...sooo why not use the one that was previously purchased and just plug in new player. Am i wrong or does it need a harness thats made for kenwood AND a 04 GM?

Ok. recheck your harness. WIth some brands yes the harness will plug into the radio from a different manufacturer but recheck the wire colors. They usually change pins out. For example whats power on a particular pin may be a speaker wire on another brand unit with the same style plug... so get the harness that came with this radio. Check the pin location and wire color on that pin to the other harness. I almost guarantee that there is a difference. Hopefully you didnt damage your new cd player... let me know how it goes...

    oh i misunderstood you. Yes you should be able to reuse the harness adapter that plugs to your stock wiring harness of your truck. NO you cannot use a pioneer radio plug on a kenwood deck and vise versa...

    I thought you switched radio brands but used the pioneer wiring plug on the kenwood deck.. whch can happen and its not good...

    if you took it appart and wired the new radio plug to your old harness adapter that should have worked. You may have to try a few things like hooking up or not hooking up the blue remote wire, etc...

    also make sure you didnt pull any wires out of the harness adapter...

My daughter has a 98 olds 88 i removed the stock stereo and put in a pioneer cd player but i didnt see any wire on the stereo side for the elec. antenna i was wondering how i can wire it to work

Most aftermarket pioneer cd/radio decks have the electrical connector for the antenna that I've seen.

Is this a cd only deck, or does it have radio functions?

Did you use a new harness wiring adapter to get the pioneer radio to work with the old harness?
There should be a color coded set of wires for the power antenna on that. And, then the Pioneer radio should have wires that were labeled for the power antenna.

Had the same problem with my 2004. Replaced the stock radio with a aftermarket pioneer unit. If you replace it make sure you by the aftermarket harness so it will plug right in and all your chimes will work.

Check to see where power is coming from for the new unit . It is possible( I have seen this before) that the wire supplying power to those lights was spliced to give power to new deck. It is also possible installer accidentally loosened a plug or connector, (I have seen that too) Good luck and please don't forget to rate. Thanks

to install this unit in your a beginner i would strongly recommend buying a aftermarket radio harness (this harness will attach to the wire plug in your factory deck simply unhook the factory player and attach this harness to the plug you just pulled out of the factory unit) once this harness is installed on the factory plug it will be a simple colour match (just attach wires to pioneer wires IE. red - red, white - white........once all the wires are attached install in dash recommend buying a mounting unit for this net part it will hold the deck in place in your dash...........after that is done install your pioneer unit push it in place apply power by turning car deck should turn on and work if it does not turn right on look for a source button on the pioneer unit and hold it down till the unit turns on
good luck
hope i was able to help

Wish to purchase a certain model am/fm / cassett in dash player deck single dimension

Well, I finally just broke down, went out and purchased a brand new am/fm/cassette player. These type stereo decks are kind of scarce now -a-days. It was reasonably priced and hope it will last longer than the old Phase Linear PCR4500.
Thanks for sharing and caring.

Best Regards,

P.S. The new rig is a completely different name manufacturer.

Problem with deck B on Pioneer CT-W205R

Better tape decks, like Pioneer, may use a different mechanism for record/play than FF & REW. So it sounds like a belt or mechanical link for the REC/PLAY has failed.
