Hello all!

I recently finished messing around with the AUX IN setting on my Grande Punto Active. I have found it is possible to connect a cable to the back of the stereo (standard stereo). Here i will show you where i plugged mine in, & what i did to make it function properly.

First, you need to get the connector for the back of the stereo, which looks like this

- Note that the end has 2 connections. Dont buy this one! You need the connector with the auxillary connector, as shown in the top picture. These can be bought on ebay for about £8.

This then plugs into the back of your stereo (To get this out, you need 4 pin-like objects, and put them into the holes in the stereo, and pull all 4 simultaneously out. I used small screwdrivers).


This is were i got stuck. i plugged my iPod in, and i only got sound from one side of the car (you may have the same problem) but when i slightly pulled out the iPod, the audio WAS being sent to both sides of the car, and in perfect quality.

After a few hours of messing around with the cable (soldering etc.) i found that the wires going into the back of the stereo were wrong. The ground wire (which was the middle wire when i bought the connector (i think red)) had to be moved around, as did the other 2 wires (i tried ground in the bottom, middle & top slot). After a while the combinations worked, and sent audio to both sides of the car.

You might not have this problem however.

One tip im going to give you now is that the auxillary cable can be run down the back of the stereo, and where the air conditioning controls are, down to where the two cup holders are in front of the gearstick, as shown the image below.

- Its quite a handy place if you dont want to spend anymore; but i suggest you do.

Next up, i wanted it to look professional, so i bought a connection from Maplins for £1.50, which converted the MALE aux in, to a FEMALE connection, shown in the image below.

Buy here:http://www.maplin.co.uk/Module.aspx?ModuleNo=1154What you need to do for this is cut of the end of the auxillary cable with the plug on, NOT the end going into the radio, and you will see 3 wires. You need to do some testing now, to see which cable needs to be soldered where on the connection shown in the link. Once you have a full circuit, you know that the cable belongs on that connection point.

I then drilled a 6mm in diameter hole into the pannel just in front of the handbrake, as seen in the image above. However i needed to spend around 2 hours sanding down the panel because it is 4mm thick, and the connection from Maplins only allows for surfaces of 2mm in thickness; frustrating i know, but worth it.

The cable should go behind the heating controls (as stated before) keep going down, and under the gearbox. You can take out the mock-leather surrounding, and you will see your cable.

This then allows you to have the connector fixed at all times, with no chance of the wire breaking or fraying, which may happen as a result of friction when the cable is placed in the first suitable place i mentioned, as there is a sharp metal piece just out of sight, but you can feel it.

This is then all the drilling, soldering & sanding complete.

I went to Halfords to buy a cradle for the iPod, and found the best place for it to be sat was on the inside wall of the passenger well, as shown in the picture below:

This isnt the one i bought, but you'll get the idea: http://www.halfords.com/webapp/wcs/..._productId_709111_langId_-1_categoryId_165635.Final thing i thought was a nice idea, was i bought a shallow USB 'cigarette lighter' charger, bearing in mind that it is a very shallow connection. This is the one i bought for £3 at amazon: USB Car Cigarette Lighter Charger for MP3 iPod, iPhone etc.: Amazon.co.uk: Car & Motorbike - I also added to pads to the side of the charger, because the socket is fairly wide aswell. This stopped all the rattling.

and your done! Hope this helps you, it certainly sounds & looks proffesional, all for a few hours work, and for under £30!!

Please comment if this helped you!!

Excellent, ta. I just fitted the aux lead to mine, turns out I bought the wrong one from Ebay with a blue connector for the radio, it fitted at the wrong end of the socket. Two minutes with a sharp knife fixed that. There's a large hole at the right-hand top of the glove box which gives access to the back of the radio if anyone wants to keep the lead in the glove box, I dangled mine down the back of the radio into the tray behind the cupholders.

There's another guide here.

HOWEVER! That link you give for the Maplin 3.5mm connector is only for a MONO connector. Did you get a stereo one?

i am busy doing the same thing. I think my version will look nicer when im done....

Because my 3.5 female plug is placed next to the hazard signal. it looks neat. Not like aftermarket crap, but as a standard fiat option.
 
Glad it has already been useful :) I thought I would post what I did because there are some things which I felt were unclear in other explanations, so I hope mine will sort things out. I also wanted to throw some ideas out there as to where to put cables

Yeah I did buy a mono connector and I haven't had any problems, because on it I could attach the left feed and the right feed to the switch, as well as the ground. I couldn't find a stereo one, but I think it would help.

Next to the hazard sounds nice!! Only thing is, wont you have wires down your dashboard?

Post photos for me, I want to see everyones handy-work :)
 
this is my result

in real life it looks nicer -> bling bling and a phone camera doens't go well together
 
im going to give this a go..
if i buy the wire you have in the first pic, can i just plug that in at the back of the head unit and plug my ipod in or will i need to buy another wire to so that?

you said you had to change the wires around, what order do they need to go in if it doesnt work the way it comes?

and does this allow control of the ipod from the steering wheel?

Hi vicki!

yeah, simply plug it in the headunit and it SHOULD work fine when you plug it into your ipod. I bought the same cable, but it didnt send audio to both sides of the car because the 3 wires in the yellow connector were wrong. Give it a go first though. You wont need to buy any other cables to make it work.

I cant remember what order the wires should have been in, a bit of trial and error to be honest. all i had to do was solder and resolder the wires in different places :)

does this allow control of the ipod from the steering wheel?

certainly does!! you can control the volume buttons, and the mute button, but the up & down arrows on the right of the steering wheel dont do anything.
So yes, but its limited :)

hopefully this helps, let me know how you get on and how it looks!!
 
If anyone has problems with the connections there's a diagram of the connections on the top of the radio. The connector is the one on the top of the two, and from the back of the radio the connection is on the far left. I think they were labelled L earth R . The common (earth) is in the centre of those.

You can see the yellow connector in the pics in this thread. The three wire connector only provides audio from the iPod. It doesn't allow any control of the iPod, although volume and mute of the sound system from the steering wheel operates normally.

Maybe a silly question but does Blue & Me still work ok with this?

I use my USB stick with audio on it but Laura wants to use her iPod every now and then - need to be able to use both (not at the same time of course!) :rolleyes:

You do realise there's 2 USB ports? Well there is in mine

This was part of the reason I had to re-wire some parts of the connection; because the centre wasn't the earth wire. It might have just been a dodgy wire to start with. Try it the way on the diagram like mozzarella says first though :)
 
You can but you'll find that B&M is plugged into that very socket so its one or the other.

:rolleyes:

how you getting along willw?

Is it possible to hack into the existing B+M wiring into them sockets so that there is an audio in and the B+M in at the same time? my theory is that, if you say "stop" to the B+M and then play your ipod or whatever through that socket and press the cd button repeatedly you should be able to get it onto source. As the book says that AUX will not be selectable when there is no media input. then when you get a phonecall or something and B+M kicks in you will either have to quickly turn off your ipod OR blow your head unit perhaps :)
