STOCK radio aux/input hack? has it been done?

[Devilman]

Just curious if anyone has done this to a stock head unit or the cd unit. I have both, radio works fine, i dont know about the tape unit, the CD unit is of typical fuctionality at this age....none (spits alot) ...anywho, i was wanting to hack in an auxilary input for use with an MP3 player, not necassarily an ipod. if anyone has done this or can offer any suggestions (outside of buying a new head unit) that would be great.


thanks in advance for any input on the subject.


turn your head and cough!

I think the only way is to check if the tape player works and use one of those old tapes that has the headphone input connected to it and plug it into your mp3. Pretty sure thats the only possiblity.

Yes getting one of those "cassette to aux" input devices works well - I've been using one for a couple of years now.

You'd be better off just swapping in an old Legacy Headunit or swapping in one from a newer car. Trying to modify to do it is very difficult.

Try doing a search for pinouts. I think andvic has a diagram in his locker for the cd player input. If you're ambitious enough you can get sound in through there. I might have them on my computer if you can't find them searching.

The pinout idea was what i was gunning for...awesome...i will search on and about (i did a little searching but didnt find anything)

if anyone else has any info, please chime in. I dont mind splicing and slicing.

thanks again!

I don't understand why with as many bells and whistles that these cars had, that they didn't have an aux input (Granted, what else in 1992 besides a CD player would you plug in?)

I did this some time ago, but I have replaced the stereo now. The 13-pin connector is easier to play with than the 8 pin. The problem I found was that I was powering my mp3 player off the lighter socket and you get a loud rpm whistle over the music. Better to use the filtered power provided by the radio and step it down to what you need with a voltage regulator.

Below is the connector from the P411 radio to the P511 single slot cd player or P611 cd changer controller:

This is for Panasonic model P113 or P114 80W Cassette/Receiver.
As labeled on the bottom of the unit: Model No. 86201AA350, Ref. No. CQ-LF1111Z.

As Numbered on the female DIN socket:
Pin 1 NC
Pin 2 Line-In Right
Pin 3 NC
Pin 4 Line-In Left
Pin 5 Signal Gnd
Pin 6 CD Play (or Remote Amp In) (send 12V to this to activate amp for remote device)
Pin 7 NC
Pin 8 Mute (input)
Pin 9 Acc Out (filtered power)
Pin 10 Batt Out (filtered power)
Pin 11 CD Stop (input)
Pin 12 NC
Pin 13 Gnd

The story behind this pinout is a long one--suffice it to say that Panasonic SUCKS. They consistently were annoying and completely uninformative to me and my Subaru dealer in our attempts to find the pinout of this connector. In the end I ended up disassembling the whole stereo, reverse-engineering the schematics, and finally figuring out from them what each pin on the connector did. For pins 8 and 11, I'd like to thank Brian S. for his help in identifying them! Probably the logic levels to those two pins are 0-12V just as for Pin 6, but I haven't verified this.

Below is the pinout from the JDM P611 cd changer controller to the trunk mounted cd player on models with this option. Also applies to the combined single DIN CDcontroller/Radio/Cassette fitted to european models and the subaru/panasonic unit used in the Legacy. READ THIS WEBPAGE. http://q1.se/cdcemu/

Pin 1 = CD-C data line. (you need to transfer the bytes on this line)
Pin 2 = CD-C clock (you need to keep a 8uS clock signal on this line 4us on 4us off)
Pin 3 = Acc (not required for comms) Note to self: Supply voltage (12V unreg)
Pin 4 = CD-C strobe (you need to send a 4us pulse after the first byte and last byte of packets)
Pin 5 = RM Data (this line has data back from the head unit)
Pin 6 = Acc (not required for comms) Note to self: Supply voltage (12V unreg)
Pin 7 = NC (not connected)
Pin 8 = GND (you require a common ground to head unit)

I often get the question if it's not just a question of shorting two pins. The answer is NO - never try it, it will not work! The radio must receive a valid signal to enable the CDC inputs. If it does not, the CDC input is disabled within a second.
