How did you check, @mnvishwa? An input will show 0V with nothing connected - it is an analog input, not an output. If at all, one has to check the *output* of the device one intends to connect to it, and that also with an Oscilloscope, not a multimeter set to V AC.

Why would you be worried about "safe and permissible voltage range" if you are using conventional outputs expected to be wired to Aux-in (e.g. EP Out of mobile phones or music players)?

Dear DerAlte,
I'm basically from the Mechanical background and I have minimum knowledge about Digital or Analog inputs. Experiment is done with the help of a friend from the Electronics background.
I will create a DIY thread, it may help the other punto owners also and try to answer your queries.

Would such products work (in 2011 Skoda Laura)?

The mention something like this;

Please make sure your car have the mp3 decode function, that can read the mp3 file from U-disk.
Make sure your car has aux 3.5mm port.
Only used on car aux by U Disk.

Not sure what this U Disk is or how to figure out if the system has mp3 decode function. If the system plays MP3 CD's - does it mean it has MP3 decoder?

Sorry - if this sounds very noob :(

Your thoughts would be highly appreciated.

They also mention:
This USB charge cable , If your device charged by 3.5mm audio male jack
Take audio as well as video signals from your camcorder
or iPod. cable will transfer high quality audio and video for you.

Seems very confusing at best.
Can your HU read MP3s out of a pen drive ?
If yes then HU logically has an mp3 decoder.

Yes!

The very reason I am considering this converter is that I don't have USB slot in my HU. But - it does have a CD player which plays MP3 CD's. Does that mean - it has that decoder?

Well yes logically it must have the decoder.
I dont think such a contraption is very popular and I have my own reservations on whether it would work.
Ideally the aux input would not be decoded as it would be receiving an anolog signal direct from the source connected to aux.
The best way to find out is to buy and try.
Worst case scenario you would have wasted Rs.150

On second thoughts i wouldn't want to waste Rs. 150.
Doing a basic google search of the device brings up a lot of negative reviews.

I seriously doubt that they would use the 3.5mm headphone jack to charge. It is not designed to carry power safely.

Strange! Haven't heard of any HU put power on the Aux-in jack. Nor have I heard of any HU expecting a protocol-controlled byte stream on what is a standard purely analog line that Aux-in is. How would the HU list directories and access files otherwise. From the other side, I haven't heard of anyone putting an analog signal on the 2 USB pins either (the other two pins are +5V and Ground). iPod has Audio Out (even Video Out) pins defined on the dock connector, but that is not connected to USB.

Sounds really dicey IMHO - "should not be used with anything other than U-disk" is too much of a rider.

Audio Gurus, Looking for HU replacement for my 2010 i20 as it stopped working and not able to fix for 2 months running behind couple of service centers and HASS.

Requirement: Use the existing Speakers, steering controls (it just has the volume, mute and mode). If possible Blue tooth and GPS.
Budget : 15K.

I found Sony - XAV-68BT relevant to the requirement.
Kindly suggest options.

Look at the India websites of Pioneer, Kenwood, JVC, Alpine etc. for a 2DIN HU. Any of these is far better than Sony. Check the price of the models you like on Snapdeal, etc. then check with dealers near you (they sometimes give a lesser price than the online shops). Audition it before buying to check your comfort with the menus, features etc.

[arnabchak]

Just a passing query:

HU- Pioneer FX 559UI
Car: Wagon R CNG
Speakers- JBL 6.5'' Co axials(mounter on Doors)
Sound Quality- Mediocre

Dont want to invest in an elaborate Sub/Amplifier set up just now.
Ramie has been extremely helpful in his suggestions though.

Can I just upgrade the front Co-axials with a Component Speakers with Cross overs? Budget-Approx. 5K(extendable to 6K)

Got a couple of options:

1) JBL 509C(older model)- Rs. 4.1k
2) JBL 609C-4.8K
3) Boston Acoustic-4.2K

(02 Speakers, 2 Tweeters and Cross over)

Will it make any difference to the Sound quality?

I am not looking for a lot from the system but some clean low and mid frequencies and not too piercing bass.

Thanks DerAlte.
After some more search as you said, planning to go for Kenwood - DPX-5130BT. Any idea on how to make the steering wheel controls work on this.
I understand we need some adapters. Can you through some light on what will it be, cost and where we can get it.

Your installer might have the adaptor with him, or can procure it. Wouldn't cost more than 2K. Check the manual first (should be available online).

Hi Arnab!

You can definitely upgrade the front door speakers to components. There are plenty of options - Infinity, Kicker, Boston, Focal etc. I would say try and audition them first. You can definitely get a good set for around 6k. I would also suggest you damp the doors. I personally feel that damping is equally important so think about it.
