..what u need is the headphone sized jack (that plugs into your ipod) with an end that is RCA stereo (red n white) these go in the back of the stereo...

hook everything up, and voila...

(no need to tell u what u already know, as far as pressin aux.. and all that..)

The AIWA CX-ZR525 wont play cd's, it will only pick them up and leave them there with no music

Presuming that other sources work okay and the the cables are connected correctly.....Try a CD Lens cleaner.

If that doesn't work then it's time to open up the unit and manually clean the laser lens. If that still doesn't work then the laser might be dead. Replacement parts may be available. Whether or not you can do this as a DIY repair though is questionable. It depends on your skill.

I have a model nsx 3150 and the cds skip a lot

Hi,what makes the nsx 3150 skipping, is because the Lens inside the DVD section that makes a DVD plate play when inserted is weak and needs to be replaced.

When a Lens is weak,it will not allow you to watch a full movie or play a CD properly. Might stop on the way or skip

What to do is this, you will need to clean the Lens with a DVD lens cleaner.You can buy from Online stores and it comes with instructions..

But note after cleaning the DVD lens, if still does the same way,that means you will have to replace the Lens inside the DVD player section.

To replace the Lens, contact the nearest repair store or outlet around your area..

Take care..

Won't read disc

To confirm if actually its a laser problem, insert an Audio CD into the player and see if will play. If it plays, then obviously, your laser (lens) is weak. But if it doesn't play Audio CD, then it might still be the laser (lens) or a mechanism problem.

Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens.

If non of the above solves the problem, then know that you need to replace the laser to a brand new one.

To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.

Once this us done, your player will play all DVD discs again.

Good luck.....

Headphone jack size

Headphone jacks are either 1/4" or 1/8". If it's about the size of a pencil, its 1/4". If it's more like the size of your mouse wire, it's 1/8".

Aiwa Stereo

Same model, same problem. (CX NA-50) I have one that worked great for two years (at best) and I haven't used it since then. I recently decided to look for a solution via the internet.
I read somewhere else that there was a class action settlement with aiwa (now expired) since many of these units had this problem.

Cd skips

If the unit continues to skip after cleanig the lens using a cotton swab and alcohol, the optics are failing and need to be replaced. These units use Sony optics (KSS-213C I think) and are readily available for $25 or so. Any service shop should be able to replace this for under $100 total.
