well It did seem hard the first time removing it, because when you are pulling it, it feels like you are going to break the plastic or something. But once you pull hard and pop off all the clips, you realize the strength of the bezel and plastics and know how hard you really have to pull for subsequent times you have to remove it.
Yes, brute force works.
Mine didn't have the pinout photo on the back like yours :(

while I was removing it, I had in my mind, I could always get a replacement from a local junkyard for $10 if I break it, so that made me pull harder :)
I think junkyards charge list price - $10 these days :)

I ended up doing a slightly more expensive option and got a Blitzsafe HON/AUX DMX V.1 on ebay for $35 (total). Sounds great!


Thanks,

how does that Aux adapter you bought fooling the Headunit to play through the CD changer? Some kind of chip in that adapter which sends a special signal? Maybe you can open it up to let others know how it works, if its simple that is...

I don't have the CD changer. The adapter plugs in the the CD changer connector.

If you press the CD button once for the build in CD, then again and the display says something like CD1-99 and the aux input is active.

would that adapter you bought be easy to reverse engineer or is there some kind of chip and codes to make it complitcated?
I'm sure it is reverse engineer-able. I thought about prying the plastic enclosure open to see what was in there but didn't do it.

I searched the web for quite a while trying to find ANYTHING about the "H-Bus" as it seems to be referred to as. My radio didn't have the connector pin out that others seem to have.

The communications between the head unit (radio) and the peripherals (CD changer or my adapter) is over this bus. I'm guessing it's some kind of serial communications (CAN?), so it might require some electronics. The accessory seems to be able to tell the head unit what CD and track it is playing and the head unit can send commands to change disks and tracks, so it's not a simple on/off signal that could be hard wired.

If I could have found any information on the H-bus, I might have tried to build one, but the $35 I got my adapter for made it not worth the time, unless it was just to know how it works.

Thanks for this info, I connected up my mp3 cord to the radio outputs and added the mute line with an external switch to kill the radio although the MP3 when plugged in tends to quiet the radio signal quite a bit and the mp3 signal overwhelms the radio. I am really impressed by the quiet, no his or static signal provided using this method, and the connections were pretty simple to solder onto.

can you provide pictures of where you soldered to intersect the radio signal, and the mute signal?
 
If you go back up this thread you will find 02Insight's original post about connecting to the CD changer plug but if you read further, he indicated you could attach to the radio turner board output, here is his pic of the tuner card and attach points.

I ran the left/right/ground wires to a stereo headphone plug and cable then added an addition ground wire and mute wire to an external switch to kill the radio signal, but it is not necessary unless you listen to the aux input at a very low level.

Holy thread resurrection Batman!

Some great work by O2 on this thread and I want to see if we can go forward some more.

I like the

1) Navi unit audio feed option

2) Reverse engineering the (M-Bus) signals to avoid paying $50 for the Aux adapter

My JDM car has/had a rear mounted Nav unit and CD Changer (both removed at present) feeding the double din JDM head unit.
I quite like the JDM head unit look and if i can mod it for aux input I'll be happy with that.

To analyse the M-Bus I suppose I can reconnect the cd changer and capture the serial data passing between them, ditto the navi unit. Have a look at the data and then you know what's coming ;) program a pic to mimic/spoof that data.
That must be what the comerical units are doing.

There is a picture/schematic on this thread of the cd changer connector but not all the signals are shown (it's been cropped) can someone link/repost the full picture so I can see which are the data bus connections.

AUX into the radio can be done many ways. The above, is chosen because its the cheapest (FREE) way.

Here is a list of alternate ways w/cd changer:
- audio selection Switcher ($16)
- Remove cd changer signals completely, but would loose ability to play other CD's in the changer (Free)
- Switching audio jack Switches audio automatically when headphone jack plugged in. ($2 from radioshack, but requires 5 minutes more work), (was going to do this way, but mounting the external switching audio jack would require more work..:) )
If you dont have CD Changer then:
- Buy Honda AUX Adapter (like $50)
- Solder pins directly to Internal Tuner (more complicated, requires a manual switch to enable mute or a transistor to auto ground mute when audio signal sensed)
- Solder pins directly to Tape audio channels. (has complications)
- Use navi l/r ch inputs, w/navi mute signal (not confirmed yet,but if works, probably needs external switch to enable mute)

So this method may not be the simplest, but surely is the cheapest, because all you need are 3 pieces of wire and a computer speaker cable, and a blank cd. (All scrap parts basically)
 
Got a question. I am replacing a wrong iPod connector that was from a Kenwood unit, with the correct iPod connector for my Pioneer double-din. I know of removing the glovebox, and I know of the two screws on the right side located inside the glove-box hinges.
Question is, are there/where are there screws on the left side of the radio? You only show the right side, how do I remove from the left side?

There are only screws on the right side, and just clips on the left. It will seem stuck, but with some hard pulling, the bezel does pop off and your hands hit something when it does. :D

Here are better pics of the bezels and mounting points:

I just registered to post that i am also in the process of adding AUX to a stereo without CD-Changer or Navi. I have tried to Ground/+V to the Bus Out Pin with no success. I am intrested to know if retepsnikrep has made any progress in capturing the serial data on the Bus pin.
Also, an intresting pdf can be found here
 
I find it amusing that with the advanced technology of the '99-up Honda Insight, that it came from the factory with a cassette deck. I mean, CD's were out in the 80's people! They might as well have put a freaking 8-track in the thing! LOL!

Why a cassette deck and not a CD-player? It's not like CD-players are expensive in the year the Insight came out! Sheeeesh!
 
Mine came with a factory CD player. In fact, a CD changer. And thank goodness for the tape deck, as modern cheap factory units are CD only and there no way to hook up an mp3 player/phone without an FM transmitter (ugh).
 
i have the cd changer laying around and cant put ot on my car ia there a way i can just use the cable coming from the changer. i am tech saavy and can solder i was wondering if i can just cut the wire and add the 3.5mm cable and a switch and use it like that. if anyone could tell me how set this up as the pinout on the changer is damaged and i do not know hoow the Honda bus wires work
 
I forget the brand on the CD changer back there, but I used something like this:


Worked like a champ.
