Thread: DIY alpine ai-net with rca/head phone adapter for ipod? gurus needed

Sorry to bring up this old thread but it has helped me to solve the aux-in problem of my head unit. So thank you guys for your post.
I just followed the steps stated in the 1st post but since I can't find any available ai-net male plug, I have to solder some wires directly to the circuit board of the unit on pins 4, 5 & 6 of the ai-net port.
My unit is an old MDA-W700J. If someone has a similar unit with a missing manual, just follow these steps:
To access the unit's special functions including the "MUTE ON/OFF" feature, you have to press and hold the power button for several seconds until then you will be taken to the hidden menus. Here's a pic...


While inside this menu, the MONO button also functions as the MUTE toggle switch. It must be set to MUTE OFF...

Just press the power button once to return to the main menu.

It is also very important to locate the pink/black wire in the harness plug...


Then you have to install a switch in between that wire and the cars body ground. This is just a temporary switch which I used to see if the aux function will be activated...


By now, you will be able to toggle between the main menu and the AUXILIARY mode if you have properlly installed the switch...


If you want to connect multiple audio devices such as PSP, iPod, or external DVD players, you can also use a multi-port RCA hub for your own convenience...


Well that's about it guys. Good luck and happy hacking.

I am hoping the 2nd gray cable suggestion is correct; I'm bout to open up my console to splice "ai-net" harness and this to hook up my new ipod which will be here Monday. I have heard/seen many of those FM transmitters for the sound quality seems to suffer; plus I don't want to have to F___ with changing frequencies, etc. on long trips.

Can anyone confirm if on the 2nd gray cable - the green is left channel, and blue is right channel???

hello ppl i have these two alpine cassette players 7293js and tda 7554 and i was wondering if i could control my usb mp3 player or ipod (scanning tracks and adjusting volume) through the contorls on the HUs

I apologize for resurrecting this old thread, but I have a similar problem.

I just got a AUX cable for my CDA-9851. It's Ai-NET on one end and a regular 3.5mm jack on the other.

Plugged it in and it works...sort of. It's awfully quiet. Really quiet. The interesting part is - when i touch the metal case of my iPod, it turns loud.

So what I did was - got a wire and with one end touched the HU metal case, with the other - the iPod. Perfect sound!

I'm no expert, but I think the AUX cable is not grounded properly...any ideas how to fix it? Or just get another one?
