It looked interesting stuff while one guy was asking for help to power these PCBs. He told its sold in Pune also (in kit format). I took his email Id on the paper bill which I kelp in pocket. Unfortunately my wife washed that pant in WM and my plans too washed away.

Now somebody please provide source for this. I would like to upgrade my HU again with some more R&D on sound Q.

look in local electronics market, I am sure shops which sell those desi sound systems have this.
Local electronics parts shop can be located using justdial

the FM kit should be Rs.150-175 excluding the IR module lens.

Nice DIY. I know this is for the kicks but stuff is available in the market for those who don't know. Glued to this thread for more ideas and attempts.

my original idea was for HU which do not have a AUX input option.
there are other products and possibilities for HU which have a AUX input.

It would be a good idea to sell this for non-usb head units. May be a cheap solution but works for most of us. Please do post more details and I would be interested to buy one.

It has 4 Pages , I didn't uploaded it initially because I thought you had scrapped the project.
Here it is (I am not able to attach the file its 1 MB) PM me your mail iD I'll send it to you.
Look in Page 3 at IC401. It is an Audio Processor and is controlled over a I2C bus. I tried to search with BD3808FS-FE2 but could not find any relevant result. I think it should be BD3805F or similar. There are multiple inputs to this chip but only 2 are used 1 is Radio and other seems to be a differential input (from CD).

To use other input on the Audio processor chip does not seem to possible as the Channel is selected by software. You can use the same channel as Radio which in this case is B1 and B2. I personally cannot sacrifice the Radio so what we can do is put a Switch in between and let it select the channel.

The amp is a TDA8588AJ.

Probably the software already caters to the 3rd input - quite likely as AUX-IN. May not be explicitly written in the HU manual, but if one extrapolates the commands from another HU of the same family (usually they share the firmware) one can decode how to get the controller to switch to the 3rd input.

Pretty sure that folks must have heard the story about how NASA folks spent millions perfecting the ink pen which can write in space. The russians on the contrary, simply used a pencil in space!

@carboy, you have an AUX port. Just use any player of your liking like Ipod, mp3 player on phone or anything. Get a sterio audio cable which has got a 3.5 mm jack on both sides of the wire, stick one end to the player, another to the HU, switch the mode on the HU to AUX and you are good to go! The wire costs around 15 rupees at the nearest electrical shop not in Croma kind of shops. MX is a great brand for cables.

I saw this module in Pune Electronics Lane, Budhwar Peth. One shop Govind electronics was having it for 190 Rs to be inserted to 12V cigarate plug in car, has remote control, and transmitts to FM. Take USB, SD card as input with FM radio inbuilt. No DIY just use it. Without FM it has option of output wire connection for aux in of HU,
