I don't know what the white one is for, it must be for an ipod module which is available for this HU.

You can still add a subwoofer using line level output.

Hi Sankar,

I'm planning to put a decent head unit instead of the default OEM one. I saw that you got that audio panel cover for astar. May I know where did you purchase and at what price. ?

The installer got it for me and i don't remember how much it cost. Should not be very expensive, you can source it from the Maruti authorsed service/spare people.

All,
does the stock NSCR-05 HU support decoding through the Aux input ?

I am looking for an alternate input source other than the radio and CD. The unit I have does not have a USB function.

The owner's handbook for the car says that volume control for the audio played through the AUX is as per the source player. Considering this, the stock HU may not have the decode feature. If this is true, then the next question : What is a good source of input to the AUX port ?

Decoding from which encoded signal?

Aux-in port is an analog input. What it expects to be fed is an analog signal, like what comes out of the earphone port of mobile phones and music players.

The owner's manual of the car only says that:
1. Keep vol of the HU at min
2. Keep vol of output from the other player at a reasonable level (so as to not cause distrotion).

Based on this I assumed that the Aux port is a point to connect another playing unit using a stereo cable.

My question comes from another un-related point.
I had ordered a USB-Female to 3.5mm stereo adapter for a different purpose. The description of this cable says:

Not all the car with this interface can use this kind of connector. Some car AUX without decoding function, so can only use MP3 device. (only car AUX interface which have the function of read U disk can use this kind of line)

Since I will have the USB-Female to Aux 3.5mm cable, I was wondering if I could use a suitable device to input content through the Aux port, and if the HU can then play incoming signals.

My guess is that some manufacturer support USB input through a 3.5MM TRRS connector for some HU's , and the adapters for these HU's are flooding ecommerce sites with a cryptic disclaimer that condor stated above, and giving false hopes to people that their head unit might support USB input

Thanks, it makes sense now.
When Condor asked his original statement I was wondering what I was missing.

Coming to Condor's question, The unit on the A Star is a very basic unit. I doubt it supports any encoding - decoding functions. It does not even support scrolling of long file names, only the first few ( 8 if I am not mistaken ) characters of the same are displayed

Correct. Aux-in in almost ALL HUs accepts only an analog stereo signal.

Yes, a few old ones (none available in India) did support USB protocol over the 3.5mm Aux-in jack. That cable is meant only for those, and I guess are in the market because they need to be thrown out of the stockists' stocks.

USB *does not support* analog signal. The 4 pins are 5V + and -, and data + and -. If you connect this cable to the USB connector of a disk drive or PMP (and the other end to the Aux-in of the HU), *nothing* will happen since the hardware USB handshake protocol will not start (USB is not dumb signal transfer). The cable will be a waste.

Sankar, any further details about this module for the NSCR-05 ?

[condor]

Some searching & reading about the HU in the A-Star gave this:

Two models of HU: the Nippon NSCR-04 & NSCR-05 New. Manufactured in India.

the NSCR04 has a CD changer connection and a Hands-free kit connector at the back. No Aux port.

The NSCR-05 has an Aux port at the front, and a Hansfree kit connector at the back. No CD Changer connector.



Image Source: Circuits Online

There is not much information otherwise regarding available kits for these HU's. Some posts said that we can use the 13-pin connector to connect an ipod to the CD changer port.

An Aux cable seems to be available:

The connections are said to be as:


Image Source: Circuits Online

Trigger 1 & Trigger 2 are to be connected via 1.5k Ohm resistor

But no clear info if this connection will work as an Aux-in for an ipod / mp3 player.

**************


Question:
Does anyone know what type of connector is the white one - (Hands-Free Kit connector) ?

Guys, to pick your memory: Do you remember the stock setup of the A-Star ?

The car has six speaker positions; One in each door, and two on the dash.

Are there any speakers in the dash ?
If yes, how are they connected ?
Are these components ?
Does the car have a stock set of cross-overs ? ( guess not)
How are the wires to the dash routed ?

If I want to put in an amp ( no sub, just the F & R speakers), what do I do ? How to wire it up ?

Reviving this decade old dead thread.

I am looking to change the ICE setup my 2012 A-Star Automatic which has 6 more years of life left in it. The car is currently without ICE.

Proposed Setup:
Headunit: SONY DSX-A410BT Car Stereo
Front and Back door - Rainbow Experience Line coaxials ELX6P (Expected date of import mid April)
Underseat sub: Zoook Moto69 MonsterX1 240-Watts RMS or 2400 Watts PMPO Underseat 8-inch Car Subwoofer with Inbuilt Amplifier (Black)


Removed setup:
Pioneer X4690BT Headunit
Hertz EP2 2 channel amp
Front door - Rainbow EL 6.5 2 way component
Back seat JBL 6.5inch Coax

Request opinions on new setup!

hey Mohit, I guess I will leave it to the experts to answer your questions - but till then could you check my last post from 3.5 years back, immediately above ?

TIA !

What is the budget you have allotted for the audio upgrade and where are you from?

Please do give this so we can suggest options in case there can be changes done to the Proposed Setup.

[Mohitkumaar]

Total budget is around 40,000 (~5%)

I am from Delhi.

I do not want amplifier because I want underseat active sub.

Music choice is typical Bollywood fare with some English music. I care for warm sound above all else. The music should be sweeeet.

One query I also want to add

Since the coaxial will be running from the wiring harness, will the stereo also send signal to the active sub from the RCA preouts?
Will there be internal audio signal separation in head unit about what frequency goes where?

@condor

For the front ones, they came empty in my case.
Not sure about top end ZXI manual though.

In my case I plan to leave them empty because Onemotor does not import 4 inch rainbow coaxials in India.
