Hallo Mr. !! I have a question please? My Car Hifi Clarion DB538RMP + MP3 have on the behind side 2 Round ( one red, one withe ) kabel slots. Is this the AUX slot? Can I take my Iphone on this slot? Because I want to heare musik with my I-phone I-pod in my car!! Thank you, for your help

What code? There should be no code for that radio.

hi,at the side of the gearbox there is a green round cover when it is removed there is a fork like lever there they normally brake or it can be faulty clutch parts that is fitted.hope it is usefull

According to the specifications on the Clarion website it has:

• 4ch/2V RCA Output (Front/Sub)
  So in answer to your question I believe it does have RCA line out.

Halo Mr. Marno,
Please install dulu MP3 driver di PC lalu hubungkan PC-MP3 degan firewire ( ya usb cables tersebut) maka mereka akan bisa berkomunikasi dengan sempurna. Sampeyan tentu sudah bisa drag atau copy file dari PC ke MP3 nya.

This link is for a pdf file, different model number but I think you'll find wiring is probably the same.

The only CLARION code available for free (using a serial number ) from anywhere on the Internet is if your radio also  has a BARCODE SERIAL NUMBER beginning with C7000000 + + + +  on a label somewhere on the metal casing.


(There are usually two barcodes on one label. The one required is the lower one )
 
If not then it will only be available from  your Main Dealer or a Decoding Service or your local Car Radio / Audio Store who will connect a laptop to read/recode the memory chip (EEPROM)

There are usually two options 

1...See if you can tease the jammed CD out through the slot using another (old) CD

If not

2...The player will have to removed from the dashboard and opened up to remove the jammed CD.

Make sure you have the Security Code before removing the player.

.
 
If you do not have the code  then POST ANOTHER QUESTION

quoting the radio MAKE+MODEL plus ALL the LETTERS+NUMBERS on ANY LABELS ,BARCODES or STAMPED IN THE METAL CASING
 

note: Unfortunately not all radios can be decoded using the Serial Number
 

THe red wire is to be connected to power from the ignition.Meaning this wire should only be hot, when the ignition is on..

You can try a commercial laser disc player cleaner or have it professionaly serivced a repair store

this proble is usually caused by the tel mute cable getting trapped as you push the radio in to the dash, pull the radio out of the dash and see if you can see if any cables have gotten caught in the cage
