Re: "Kitchen Sink" GPS/DVD & Multimedia Head units reviews & options


Hi john I ran the gps wire straight up through the compartment in the center of the dash through the clip hole,tucking the wire under the lip out of the way and I put the antenna against the windscreen and just sat it under the dash mat and I have had no problems with cd's not playing at all.

Re: "Kitchen Sink" GPS/DVD & Multimedia Head units reviews & options


Enabling the Phone button, Series 3 and 4. This applies to Xtrails which had the factory 6 stack cd player fitted with the Handsfree phone option.
Hi Guys,
           Since installing the Koason last year, I have been disappointed that the Phone Connect button on the wheel did not work and programmed the Source button to do this. This is due to the factory Blue Tooth unit known as the TEL ADAPTOR unit being wired in between the wheel switches and the Audio Iso plug. While it passes the other functions, the Phone Connect does not get passed along. The tel adaptor is mounted in the space above the back left hand wheel arch. I had 3 attempts at getting that flaring off the inside and stopped short of doing damage. Time for a re think.

 The harness that goes to the Tel adaptor is under the passenger side sill. Remove the kick plate and your there. There is a small harness which leaves this one, I went slightly towards the rear of it and removed about 10cm of the tape on the harness to make it easy to locate the cables required. Unfortunately there is more than one of each colour in the harness so you need to check with a multimeter that you have the right one as this one harness carries other functions to the rear. The four wires seemed close together in the harness and are the smaller wires. I used a small dress makers pin to go through the insulation to test each wire.

With your meter negative to ground, and the accessories on, locate the purple (violet) with the 2 slate markers and it should be about 5 volts. Press the Phone button and this should go to zero, while Seek up should be 1.7 volts and with Vol Up returning 3.3. Locate the Pink with the 2 slate markers and it should be about 5 volts going to zero when the Source button is pressed, 1.7 volts with seek down and vol down returning 3.3 volts.
Check the white with the two slate markers and you should find about 3.3 volts to 5 volts. Depending on the head unit, you will see this voltage fall when pressing the Seek up or Vol up buttons. The Phone button will not change the volts measured. If this isn't the case you have the wrong white wire. Locate the Orange with the 2 slate markers, it should be about 3.3 to 5 volts depending on the head unit. This should reduce to zero with the Source button pressed and both the Seek Down and vol down buttons should change the voltage measured.

 Turn the accessories off and cut each of the four wires. Bare the ends of the White and Purple coming from the front of the car, join and solder them together, add some heatshrink or insulation tape. Now do the same to join the Orange and Pink.
The four loose ends coming from the rear, insulate them separately. You will need to reprogram all the functions for you wheel controls. I had several attempts as the Koason seemed to have trouble with the Prev key. I found the order of Phone, Source, Next, Prev, Vol Up and Vol Down seemed to fix it.

Once all done, retape the harness as required, and replace the kick plate. Although I did this primarily for the Koason, all the switches will now be seen at the Audio Iso plug. As long as your head unit uses Switch A and Switch B you may have a winner.

Enabling the Phone button, Series 3 and 4. This applies to Xtrails which had the factory 6 stack cd player fitted with the Handsfree phone option.

Hi Guys,
           As a follow up to the previous post, I thought it best to provide the information to those who can or have been able to remove the panel in the left rear of the Xtrail. This method does not require the cutting of cables, measuring of voltages or soldering. I would have prefered to do it this way myself, but unfortunately couldn't get the panel out. If you decide to sell your xtrail and want to put the 6 stacker back in, this mod is very easily reversed.

Before we go much further, I have not done this mod myself but I'm posting the info based on the information which we found when we did the previous mod.

 The Tel Adapter unit is located behind the panel just to the rear and above the left rear wheel arch and having fitted a new head unit with Bluetooth built in, it is now redundant. It has a 32 pin connector with 2 rows of 16 pins. With the ignition accessories off, remove the connector.
Looking from the harness side of the connector, you need to confirm the colours and placement of the 6 wires. Use this picture as your guide.

Image

 Pin 12 Violet with 2 Slate markers (its hard to tell the difference to Purple)
 Pin 13 Pink with 2 Slate markers.
 Pin 14 Grey
 Pin 17 White with 2 Slate markers.
 Pin 18 Orange with 2 Slate markers.
 Pin 19 Grey.

 If these colours are in the correct positions, then you can proceed, if not, don't.
The idea here is to link the connections from the steering wheel switches directly back to the Audio Iso connector bypassing the the Tel Adapter unit. I would suggest 3 pieces of single core building wire. Bare the insulation by 10mm or so and try fitting. If you still have copper exposed after pushing it all the way in, trim the end.

Now with the pin side of the connector facing you, make the connections. Use the picture as a guide.

Image

 Link Pin 12 Violet to Pin 17 White
 Link Pin 13 Pink to Pin 18 Orange
 Link Pin 14 Grey to Pin 19 Grey
 
 It will be necessary to reprogram your head unit and hopefully you will have all the switches operating correctly. After testing, apply insulation tape around the connector and wire links.

Hope this is of help to you.

John

Re: "Kitchen Sink" GPS/DVD & Multimedia Head units reviews & options


Hey guys,
I hvae been going through this thread, and i am not convinced on the Kosan Unit. I have been looking around now at other units on the market and have now purchased this unit, (eBay Item number: 230725397412) as well as the reversing camera, (eBay item number: 320547227238)

I expect to receive it in about a week. The unit is coming from Mildura.

I have done some homework on this, and contacted other ebayers who have purchased this unit as well. They have not had any issues with it, except for the phone button not working on the stering wheel, which i'm hoping Johngqld has sorted out for me from his previous post! emoticon

Also, Johngqld, should you fix not work for the stering wheel controls, can the factory fitted bluetooth unit be disconnected, without loosing the other stero controls?

I will keep you guys posted, and will put up a complete photo bio of the install! emoticon

Admin Edit: eBay links removed. Please do not post eBay links as per forum rules.

Hi Scot,
           For the hundred dollars more than I paid for my Koason last year, it certainly has got some features straight out of the box I like, the rear USB port and SD card in the front just to name two. Be interesting to see if the Bluetooth downloads your contacts, something the Koason doesn't do.

Now the the wheel controls. I hope you can get to the Tel Adapter (factory Bluetooth) unit. Your switch inputs from the wheel go into here, the phone signal is masked out, then the new signals leave the unit for the Audio Iso connector. If you remove the connector without adding the links, you will have no wheel controls at all. By adding the links, all the 6 function buttons will be presented to your head unit. Although I did the turn around in the harness rather than the plug, the result should be the same. I hope in the setting menu that it allows you to map the function.

With the Tel Adapter in place...Image

Connector removed and links added.......Image

 What I would strongly suggest to save yourself some work, is to install the unit first, get into the settings menu and get the other functions working. Then see if you are able to program the phone function to another key temporarily to see if it can be done. If it can, then try doing the bypass, then reprogram your settings. Really looking forward to the outcome.

Cheers
John

Re:


Hey lads

i bought one of the koason units back on page 24 or so and installed it and been having a good time with it

EXCEPT!!!!

now some of you will see this as good and some see it as bad haha

if i have the unit switched off completely then everything is fine. if i turn the unit on and use gps or radio etc then my odometer doesnt move!!

so im on 21400kms at the moment and it will only climb again if i power off the unit. all the other functions as in amount of kms left till tank is empty etc all still work when the unit is on.

any ideas??

obviously in 10 years when the car is still sitting on under 30k kms ill have to answer a few questions haha

do you think i have cabled it up wrong or can you think how it could be possibly happening in the first place???

could it be another victim of the incorrect wiring harness described in the past few pages maybe?

ideally i would like to get it fixed as anything that doesnt work properly on the exxy is annoying

would love to hear others thoughts on it emoticon

cheers
Luke

Wow mate, don't let Koason hear you, they will jack up the price of the unit straight away LOL emoticon

It sounds like the GPS/speed cable from the unit is connected to the wrong place or the Koason harness had some issues like the previous ones.

Hi Luke,
           I assume that you have a Series 1 without steering wheel controls, is it a Ti? The odometer pulses arrive on pin 18 of the Audio Iso and are not used by the Koason. Using the picture below which LesAdelaide posted earlier, pin 18 is next to the large black negative. From this picture you should have that red on the bottom row (beside the Black)and directly above it, should be blank. If it has got something in it, all I can suggest is to give it a quick snip and see if that fixes the issue. Please let us know how you go.
