hi guys.
With much help from the great guys on this forum (especially zebelkhan) I replaced my OEM orange screen with a 7" colour one. I will take some pics later on :)
I installed a TV tuner also and now get TV running to the screen :) DVD player to come later on.
I need help with an interesting issue though. The screen has buttons and the IR sensor on the bottom. This is all blocked by the OEM screen cover/shroud which is good cause it looks factory now. Problem is that the remote control doesnt work now because the sensor is blocked.
Is there anyway around this problem? |

The way I did it was to actually disassemble the screen, unsolder the IR receiver off the buttons PC board, extend its wires and place it down below. A less "clean" job would be to dril a hole on the MO's screen face plate so the IR receiver can "see" the remote.
I will take a picture of where I now have the receiver and post. |

thanks again zeb :)
I don't know if I am handy enough to be unsoldering IR sensors..... I don't want to drill a hole either in the screen face plate.
Hoping there is a creative solution out there that I havnt thought about... |

Actually it is not too bad but just like any "operation" things can go wrong...:D
I am not sure if it is doable but how about a fiber cable (the type that transmitts light like those they use in stereo systems for audio)with one end fixed in front of the sensor and the other end somewhere where you can hold the remote against?????
Or an elaborate system of mirrors....
Just some thoughts....:) |

another option - fly me in and I can do it!:D But seriously it should not be a big problem. The key is to have a right soldering iron and practice on something else before you approach the screen.
Good luck. |

I want to do same but thought was not possible
What needs to be done to accomplish this? do you have a DIY? |

Hi zeb,
can you post the picture when you have a chance? I may give this a try. Whats the worst that could happen? The IR might stop working but that aint working currently anyway :D
Will any standard electrical wire work? |

hey guys - did a search and couldn't find zeb's install thread for the carputer. Is it on this site?
thanks in advance... |
|

| zebelkhan |
I don't have a install thread as I did not have a camera to take pictures at the time. There are some pictures in my gallery you can look at though.
I used a regular telephone wire to extend my IR sensor using three out of the four wires inside. The trickiest part of the whole thing is disassembling the liliiput housing and being very careful with the ribbon cables while doing so. The cable connectors are very fragile and can break easily.
HERE you will find some nice pictures of the insides of the lilliput. Depending on which model you have, the buttons PCB may be different from the one pictured but you should only have three solder points to worry about. Take your time and make sure you use a heat sink to prevent damaging the PCB or the sensor. Also note the way it has been soldered so you do not cross the wires.
Before taking your lilliput apart, I also recommend you read the threads HERE so amongst other things you can learn how to program your lilliput so that it would automatically turn on. Please note that these pictures and links are mostly for lilliputs without a TV but they may also work on those as well.
Good luck!
Here is a picture of where the IR sensor is now. I pulled it out a bit to show but it can be pushed in and become almost invisible. |

| Hey, I did not see any mentioning about the car information being displayed on the color screen. Has this been solved ? |

| Doh!... I thought someone finally hacked the murano display controller... got me all excited :-) Too bad then, I've done carputer before...still have the lilliput, via board, and yellow cap battery from the old car in my garage. |

| Well I'm waiting for the 06 service manual to be available. I'm thinking the easiest way for pre-06 models would be to retrofit with 06 parts...may not be cheapest though and SW may be a problem. |

Someone send me the latest service manual, drop by with the car and the parts and I'll help them see if it's feasible...
Buying another Murano at this point is not a financial option for me! (After all I have to buy lots of gas now...) |

| Not quite given up, but I got some really difficult bad news today from a friend in the biz. Essentially, all the data on the 13 segment display is delivered over the CAN bus. It's a proprietary Nissan protocol that at best would be difficult to decode, and most likely impossible. However, that leaves me with no useful options just now. Basically, I have most of the HW, and a lot of half integrated SW (got bluetooth handsfree + SMS displays sorta working) that can't really be used. GAH! |

Ok, I’ve spent the last month reading threads looking at all different available options to replace the ugly looking (by 2006 standards) orange screen for my 2005 SL (I know, should have gotten the NAV factory installed)
Now, this is what I’ve found:
NO CLEAR ANSWER
This is what I would like to know, and if someone replies, please be straight forward, I would appreciate it.
BASIC UPGRADE:
- CAN I REPLACE THE ORANGE SCREEN FOR A NICE LOOKING LCD WITHOUT LOOSING ANY FUNCTIONS? >NO NAV, JUST LIKE THE ‘06
* IF NOT, PLEASE, WHY NOT?
- IF THE FIRST UPGRADE IS POSIBLE, CAN I INSTALL THE NAV SYSTEM ON IT?
Now, I know that there are a lot of threads regarding this topic, but many of them, are already over 2 months old, and tech. changes; and many of this threads, just recommend alternatives which involve damaging the original look of the Murano.
I would really appreciate any help. |

| Of course its possible, go down to your dealer and ask them for a list of what parts you'll need to buy. These might help. From 05 SM. |

I bet he is confuse now after seeing Enforcer's diagram! ;)
(No punt intended). |

| maCar |
You Bet SugarRush!!! lol
i guess that all means that is possible, correct Enfocer?
:1:
I'm going this weekend to my local dealer to get the part #s
So just to confirm:
It is posible to replace the Orange Screen for the LCD and still have 100% use of the original functions
right?
And The NAV?:confused:
thanx guys... |

| Well anything is possible but I can almost guarantee you that by the time you add up the cost of parts, labour, time and frustration, an easier (and potentially cheaper) way would be to trade your MO in for a new model with the NAV. |

Yup thats the way it was back in 03 when I looked. But, after 3 years of MOs there has to be some parts showing up out there. The trick is to get the list of parts then look around salvage ebay etc. May take a while. Maybe only buy one or 2 from dealer, then it might be reasonable.
LOL Moses yeah hehe. Yes it is possible and all will function right if you use the OEM parts obviously. |

I am trying to change that orange screen to color as well.
Please advise detail on the type of replacement screen used input RGB?, composite video ??
Photos?
Your assistance appreciated -

Well, a lot more research and work on how to communicate with the car got no where. Basically, Nissan uses CAN to talk to everything in the radio/NAV/Display/etc, and while not impossible, deciphering the CAN bus traffic is pretty rough. The guys here at work think they may encrypt it as well, or at least obfuscate it to keep people out. If you can read the protocol, you can write it, and then things get really bad for the car. Note that no aftermarket equipment I know of taps any data on the CAN bus for any car I've heard of.
It's possible, but not probable. I've given up on snooping CAN, tried to go and snoop the LED signals, gave up on that, thought about replacing the LED chip with something homegrown, gave up on that real fast, and have decided to try and do a HUD now instead, which could be real cool. More details to follow. |

It seems some want to use an non-Nissan screen, what about an 06 screen in a 05 ?
or are the connections for the color screen that much different that they are not interchangeable? |
|
|
| pbuelow |
| The problem isn't the screen so much, but the HW and logic that drive it. Anything graphical needs two things, one being a display controller, and the other GUI software. So, even if the connetions are the same, the backend won't be. To be fair, given the cost diff between an LCD and an LED display, I'm surprised they didn't do this right off the bat and add $500 beans to the cost of the car from the beginning. |

Here is some technical information about the CAN bus.
http://www.interfacebus.com/Design_Connector_CAN.html
It seems to me that it would be completely possible to use a software application to receive information via the CAN bus and present it on a screen. I seriously doubt that once you have the data in a serial stream of bytes that it is a very complicated protocol.
Atmel (common to anyone familiar with microcontrollers) actually makes a line of CAN-capable microcontrollers.
http://www.atmel.com/products/CAN/
So, if you already have a computer in your Murano, you're half way there. Now you just need software to process the CAN data and present it in a nice UI.
Too bad I have a job already...this could get time-consuming. :-) |

Pahleeeeezzzz Do a step by step with pics topic about how to replace the goddamn OEM =[
and can u plz make a topic explaining what r the parts needed and how much they cost?
seriously cuz reading this topic is sorta confusing ><
and im still waiting for the pics we were promised ><
Thanx guys and im so sorry for asking alot but its just that I hate the orange screen ><
Bubye ppl :) |

The answer to your persistent question, in short, is that it cannot be done. Unless, of course, you are an electrical genius (which some of our guys here are!) with loads of time and money on your hands. I think that it has been done once with great difficulty and expense by buying a large quantity on oem parts and splicing a lot of oem harnesses. (if I remember correctly, it never worked exactly right either). Your best bet is to just either:
-move the oem screen to the bottom of the dash
-setup a camera that will display a view of the old screen in it's new location on your new screen
-have a custom enclosure made somewhere else to house the new screen
I have been after a solution for this since I bought my car, and it just does not seem to be realistically possible to have a completely factory install. |

| pbuelow |
| You don't need to be a genius, just have some knowledge in assembling embedded computers. I'm not a genius, but I can put all this together. I'm just missing two pieces. The first is the CAN protocol that Nissan uses, which I believe is encrypted to some extent to keep people from snooping. Many cars have had their CAN network decoded, but to date, the more recent Nissan models have not that I can find. The controller, the display, and the car computer are all relatively easy. The other is time. There are a lot of pieces to put this together which will take several months of pretty solid effort. I've done some of the software already, but there's a lot more to be done. As soon as someone decodes the CAN network and can read (note, writing to the CAN network will kill your car most likely) the data being displayed on the display, then shoot me a message and I'll get back into this. I have all the parts minus the LCD and CAN board. And I found the perfect LCD display to use. |

| Ok so i dont care about the screen functioning the same, but i want like a kenwood screen and I was wondering if i can integrate the buttons to work within the screen? |

erik-
It hasn't been done yet, but that doesn't mean you can't be the first.
An easier approach might be to relocate the orange screen to the bottom of the console and put the Kenwood in it's place. Now that has been done.

Do what i did trade it in on another Mo with NAV! Sorry but it is cheaper IMHO that anything elxe you can do. |
|
|
| biggun |
| I think Grip is right, but I don't think you even need to get NAV anymore since the new Mo's come with color screens that can be tapped into. |

has anyone with an 05 taken a color screen and the navi audio video controller and just hooked it up with out the DVD box and seen what happens? I just ordered the audio / video controller for my 05 SL and I have a color screen out of an 07.
if I have too ill make my own harness for it =p
I bet It doesn't even have the right wires to hook it up heh. |
|
|
| GripperDon |
| Did you drill the holes Neatly or unsolder and remount? |

Sorry to rehash this guys, but I have some customers asking if they can put the 07 color creen in place of the orange screen.
I was reading this thread, and this is where I got confused.
You kept saying it was VERY Hard to do, sicne you have to interpet the CAN Signals, but the way I ws reading it, that was only if you wanted to add NAV, if you just wanted the Color Screen, with No nav, is this possible, without rewiring the screen????
Thanks for any help you guys can give...

jerseyparts,
From what I understand, no one has done this yet.
In addition to the screen, they would need to swap the old controller with the color controller. This does not garantee that it would work. It is believed that the BCM has some function with this setup as well (not sure). If so, you would need to swap out the BCM as well.
I really hope they try it and can report on their success.

this thread can be misleading. the guy who posted it meant he replaced his screen with a car pc and a 7 inch lcd touch screen.
in order to put a color oem screen in a 03-05 murano you have to replace the entire dash harness or make one but you cant get the connectors and buy the navi display controller and the color screen. you may aswell put in the nav box while your doing ity hehe.
in short its too much work. just go buy a 06 up murano |
|

| jerseyparts |
LOL, Thanks for the Info, I will pass it on and see what happens.
