hello eletronic experts!!
First of all i´m sorry for my english but i´m from portugal... I´m realy desperate because i have got a panasonic autoradio cq-rdp383n, and i´ve recently bought a dvd player for my car... but i can´t put the sound of my dvd player getting out on the car speakers...i´ve already bought a p2 (jack) to rca male male but that doesn´t work because the auxiliar option on my auto radio is only activated when connected to a cd box ... is there any way to resolve this??

I don't understand. Is there a CD - radio switch? How does the radio know that a CD player is connected?

I had a similar problem with my Kenwood unit. There is a 13 pin (?) connector on the back of the unit for an external CD changer or XM radio system. The system knows when something is connected by a resistor accross two of the connector pins that would be located inside the cable itself or in the cd changer.
What i did was find the part on the Kenwood website that would allow you to connect an Aux unit, find the part number, then do a search for "(part number) schematic" Use the part number with no ()'s.

This gave me the value of resistor to use, and which pins are for the left and right audio channels. I made my own cable from parts but if you're going for the cheapest fix, I suppose you could just shove the resistor in the plug...though i would recommend making a correct cable.
Parts for the cable will cost far less than the ready made cord from the manufacturer.

MrMikey83 thanks for the help! But how do i find that in panasonic? i´ve already being in panasonic site and the only thing i get from there was the manual o the autoradio that doesn´t explain nothing of that..

I did a search afetr I posted the first message and I too could find nothing. It looks like the connector on your pictures is round. Are there 13 holes? Mine is 3 rows of 4 pins and a single one at the bottom in the middle. I also learned that some panasonic receivers used a square plug of some sort.

I'll continue looking around.

Might not be much help?, but that looks like an 8 pin DIN plug - so at least the connector should be freely available!.

At least now i know the name.. i´m going to continue to make some researches how this kind o connector works...if anyone could help... I realy need it!!

thanks

The problem is that every manufacturer uses a completely different system! - but you can buy adaptors to connect different makes of CD players and car radios.

However, they are expensive! - it's not usually just a simple lead, it contains electronics (almost certainly a micro-controller!) that converts the system communication from one system to the other.

Incidently, I've got access to Panasonic UK service - BUT, they don't list car audio at all, so it's probably done by a completely different company?.
