Cool... If they figure out how to use the changer code instead, they could work with the Sat receiver.

 

It's a real product, just not out yet....

"We have two G35 we are testing right now and they seem to be working very well."

 

Whan asked about the murano:

I have no information if it will work on the Murano. As of right now
we are doing testing on the G35's, I am sure we will be doing more testing on more vehicles in the next up coming weeks. Check back with me in April and I will have more info on the unit.

Same radios?

 

As ALL of the Sat parts for the Murano 03 are identical to the G35 parts (you have to order the G35 parts!), this WILL work.

 

Yup, all the Nissans and Infinitis that support SAT all use the same Receivers, so emulating one, means it will work in all of them.

 

Another nice feature they included is the option to control an aux device via the steering wheels controls. This only works if the device has support for an IR remote, but many probably do.

 

Ooh my gawd! Salvation! I can hardly wait! Weeeeeee
Let us know!!!

 

Darn! I spoke too soon! I went to their site. I won't be able to use it, since I have satellite radio. Argh! I was hoping for a AUX input that uses the CD changer input. Darn!

 

Will this work on the Murano? I do not have BOSE.
Look at the connector it plugs into. Can we use that one?

I don't think that other AUX will work on our MOs as it says that It will work only on the 1997-1998 Nissan Maxima / Pathfinder / Infiniti I30 stereo shown above. Also it says that it is not available for sale yet (if ever). Why not just sell your XM receiver to a forum member and then install something like the Delphi kit. I don't know if it will sound any differnet than the one you have now.

You could use a different sat receiver into one of the two aux inputs. But you would lose some of the nice display stuff, like song, etc.

 

yah, the integration is what is so important to me. I use the SAT more than I will need the AUX for the DVD player, so I will stay with the RF modulator until I can get an AUX adapter for the CD plug, or not at all if it nevet becomes available. Dad-burn-it!

 

I emailed them requesting that they alter the coding to emulate the external changer instead. After all, most people that are fanatical enough about their music to want to use this, will also want Sat.

There is no hardware change to do this. It's entirely how it identifies itself to the head unit, when first queried on power up.

And we know from the diagnostics in the Murano that it looks for a changer and the Sat.

But my favourite is done with a signal generator that has RDS built in...

 

I'm a little confused.

When this AUX input unit comes out, will it work in a Murano with the Bose / SAT radio? (with no SAT installed).

 

Yes it will.

It works by emulating a Sat receiver. The Murano's radio sends out requests for identificaton on the bus. Once it's confirmed there is a Sat receiver there, they exchange some information and then it's idle until the radio asks or commands something, like change channel, use a preset, etc. or the sat sends info like, here are the preset channel numbers, the names of each of the channels on the presets, the current channel number and name, as well as the artist and song title.

I've already started to tear this apart, and you can see some of the detail on my web site, if you're into that. I am prototyping something similar to what they're currently testing, but mine will allow a pc or PPC or Palm to connect and send data to the head unit as well as respond to commands from the radio buttons, such as channel up down, channel type, presets, steering wheel controls, as well as display information sent.

I have a real job, so it will take quite a while, unless someone steps up to help me out.

The steering wheel controls aren't perhaps as sophisticated for this as you might think. Most of the controls are radio controls. Source selection, on/off, volume, are all local controls. Only the channel button is going to be sent to the remote unit, unless they've come up with something unique.

And remember, press and hold on the steering wheel channel button is another command set.

On the G35, if you have an external changer attached, you select it with the CD button. I can't remember if it's press and hold or it toggles, but I've wondered if the Murano might do the same.

These guys aren't the first to emulate the sat. Phatnoise has had a product for a while and they can emulate the sat or the changer, depending on which firmware is loaded. By they use their system for the audio, not yours. This, of course, is the best part. I like the idea of connecting my iPaq and playing mp3's off that, knowing that the navigation I run on it, will also come through the same audio path.

Put a PC on there, and you could have mp3's, the sound for video, and any other device which can be plugged in the bus, or put on through USB. This means a DAB receiver in Canada and Europe or even a TV tuner. It really opens the door to some wild ideas!

 

What abtou those of us that want SAT and AUX?

 

All I want to do is plug in my MP3 player via an aux input. I already have an FM transmitter and it sucks. Anybody got any suggestion?

Thank you, Roly

 

Roly- What FM transmitter are you using?....I use an "Audio Bug" and its "OK"..not great...but maybe I've got a tin ear....

 

What abtou those of us that want SAT and AUX?

Exactly. That's the question I posed to them... And why I suggested they emulate the external changer instead.

The problem with FM transmitters, is first, you have to have a good one. If built to FM broadcast specifications, the audio frequencies are limited to 15 KHz. Someone who is smart when they design one, will actually make it a little wider, as the filters in the cars receiver aren't going to be that precise.

The other problem, even if the transmitter is high quality, is the receive characteristics of the FM radio. You will never get significantly better than the best FM station, as again, the frequency range and also the dynamic range (quiet to loud) will not be as good as a direct input.

For mp3 playback, the player and the digital compression level on the source material will impact the quality, perhaps more than an FM modulator. But given high quality, high bandwidth source material, then the FM becomes the weak link.

Using the direct audio inputs, is the way to go. However, you have to fool the head unit (radio as most of us call it) into thinking there is a OEM accessory attached and enabled, before it will take the audio in.

We've been waiting so long for this, I started to figure out how to do it myself. I'll continue, as there's lot more application potential. I hope to attach a computer of some sort.

If all you want is audio in, and don't want the OEM sat, then assuming it works well (I expect it will) and it's not grossly overpriced, I would expect the www.pac-audio.com product to be a good solution.

As for the soluton at http://www.telusplanet.net/cornblatt/aux_in.htm

The audio conversion part should work, but it won't enable the input. So it as a complete solution, won't do the job on the Murano.

 

Jaak,

I plan to add a computer too. That was the reason I was asking you about the computer control unit so that I could add a color VGA screen to the LCD existing location. What are you planning to do with your comp or better yet what more application potential do you see?

Thanks,

Glenn

 

Hey, right on, I see you got the computer!

OK, here's what I think would be absolutely killer....

You need to get some sort of video input that will take RGB, or something that will convert the RGB to composite. The controller you just bought, if I recall correctly, outputs RGB. Then the OEM orange display get's replaced with a colour one, (or for those that already have one, you use it) and this will be set up to take the video from the computer. It might take some tweaking to get the right video hardware and the right settings on the card, to display correctly.

Since you're bringing in the video from the controller, you have the option, in full screen mode, to show this so it looks just like the original. Or you can have it in a window.

Having the radios controls interface with it, will be nice. Even a touch screen would be possible, but it's a bit of a reach. Ideally getting control from the existing buttons would be good.

The software would be a fair bit. However, we're not the first to think of this. Have a look at www.mp3car.com as an example.

What could the computer have? Anything you can put into a computer now. DVD, MP3 playback, TV, wireless LAN, Bluetooth (turn it into a hands free for a Bluetooth enabled phone), Sat, you name it. If a computer can do it, you could hook it in.

Imagine, you park the Murano, when you get home, then through the wireless LAN you load the songs you want to listen to. No discs, just sit at your PC and blast them over.

If you have wireless LAN access at other locations, or link your phone in, you could even have it check for email automatically. Imagine, driving somewhere and getting notified of new email. Not that you'd read it then (although there are speech packages that could read it for you). There's speech recognition software out there too. It's endless. It's also a lot of work.

 

Jaak,

What I plan to do is have it run naviagtion, MP3, DVD, and XM radio. I am looking to put a VGA screen in the front, do you think it will be possible to convert the output connector from the controller to a VGA connector? I also plan to add the Aux connector from PAC Audio so that I can use the steering wheel controls for the PC.

Thanks,

Glenn

 

Maybe. A big Maybe. I haven't looked at the detail of the signals in the service manual, but there is some there. The other issue is resolution and scan rate, to know if it would work.

If it doesn't, then some sort of video input into the computer would have to be the way to go.
