Plug n Play Aux-in mod for 2005 6cd radios

Bummer. I decided to not go with the ashtray install. I thought I had everything worked out: the parts, the electronics, the logistics - but it all turned out to be the wrong plan - and I broke my iPod dock connector in the interim.

 

This is what I was going to do: I have an old DLO car dock that I was going to take its parts out of, and I was going to retrofit the iPod dock connector into a slick-looking Phillips dock.

 

When I bought the Phillips dock I thought it was an iPod dock, and I had planned on using only that for the ashtray dock. It's about the same size as the ashtray, it's gloss-black, curved and looks great. Check it out:

When the connector didn't fit (they look almost exactly the same as an iPod connector) I took it apart, took my old DLO apart, and looked to see if there were any compatible components. The connector from the DLO fit inside the Phillips almot exactly. The holes for the DLO connector's PC board were a little larger, but that was nothing that a couple of small washers couldn't take care of. I took the Phillips PC board out, screwed in the DLO's connector, and I thought everything was gravy. I closed the Phillips' housing and SNAP - the DLO connector snapped loose. I tried to fit my iPod in there just for sh!ts and giggles, and it was so close - but yet so far!

 

So I reassembled the Phillips (nothing was broken on that - every part and every screw was accounted for), took it back to the store, and got my $50 back.

 

I'll probably hold off on the ashtray idea until I can come up with a better plan. I saw the mini iPod installation document and although it's great work, it's more complicated than I prefer, and if I didn't have to dremmel anything that came with the car, the better it is for me. If at all possible I'd like the option to completely revert it back to stock. For that reason, I might go for the Flexible Dock idea instead.

 

I called a home-run on my at-bat, and I struck out. A couple more innings and I'll get another shot.

No harm no foul d.scott. Nice attempt anyway - what works and what doesn't are both useful other people here. Good to see new approaches anyway.

 

My work for the night consisted of attempting to map the command for track up. I got a different command depending on whether the filler signal was running on pin 7 or not (a simple track down, which does not change track, would change it to/from the filler signal to blank). I did however, get a consistent command, one way or the other, for each track change ->

The extra 1 at the end seems to be a checksum, there on odd sums and not on even sums. Other than that...there are some common commands (highlighted in corresponding colors), but no clear patters are jumping out at me...then again, it's sorta late & looking at 1's & 0's for so long makes you a bit bonkers. Here's the same sequence, sorted in order of bits (instead of tracks).

Ideas? I'll post track down's tomorrow.

Obvious, but I'll point it out anyway:

 

Track 1-2 = Track 9-10

Track 2-3 = Track 6-7

Track 7-8 = Track 11-12

 

I can't imagine why, with so many bits at their dosposal, they wouldn't have unique codes for each track (or just one simple code for "track up").

 

I also noticed something else. I want to label these in ascending order, for ease of identification:

 

1: 1011-0001-1011-0001-1011-0001-1

2: 1011-0001-1011-0001-1011-0001-1011-0001-1

3: 1011-1001-0011-1001-0011-1001

4: 1011-1001-0011-1001-0011-1001-0011-1001

5: 1110-0010-1110-0010-1110-0010-1

6: 1110-0010-1110-0010-1110-0010-1110-0010-1

7: 1111-0011-1111-0011-1111-0011-1

8: 1111-0011-1111-0011-1111-0011-1111-0011-1

9: 1111-1001-1111-1001-1111-1001

 

Using this numbering system, line 2 is equal line 1 plus eight bits, line 4 is equal to line 3 plus 8 bits, and so on. It looks like each short, odd-numbered line (with the exception of line 9) has a lengthened, even numbered verson of itself. Also notice that these series of 8 bits repeat themselves within each line of code (with the exception of lines 3 and 4). Hope this helps!

 

EDIT: jazzy, you have mis-colored the second line in the "track 8 to 9" code. It should have a color other than pink, as there is a different line of code with the same color

There's obviously more going on here than a simple "track up" command. I wish it were that simple. I may try a different CD, or try the CD in a different slot (instead of CD1). It may tell us more about what's going on. The other thing I was thinking about was changing the nibble sequences into dec10 to see if that made the pattern more obvious.

 

~edit~ Actually...now that I look at the columns a little more, it may make the pattern more obvious to compare two bit pairs instead of nibbles.

There, that's in Dec10. I highlighted similar patterns now instead of just identical...looks like more of a pattern now doesn't it? I will have to double check 8 to 9 just to make sure that's a unique signal and not "operator error."

 

~edit~ I checked 8->9, it was a mistake. I get the same pattern all the way across now.

Ahhh, much better . It makes the repetition within the lines of code much more obvious. I have no more insight at the moment, but keep us posted with any further data.

Questions for you, jazzy... and a little thinking aloud...

 

In each track change, you list two sequences... what is their relationship? In other words, as I understand it, you were looking at the digital signal on the line... so is there a pause after the first sequence series, and then an output of the second is some sort of an ack response?

 

Beyond that, are there any other signals in the line? What I am thinking is that there is one chip that is generating the command sequence, and it repeats it until it receives an ack-response (maybe on the same lines? Maybe on another pin?) And then, assuming the latter of each series is an ack-response, it's some sort of response with some "processing" on it.

 

On this same line of thought, have you monitored the other lines during track changes, to see if they are transitioning at all? Might help in identifying the other lines, as it seems unlikely to see so many different "constant" voltages of varying levels...

 

Similarly, did you check continuity to ground on the supposed ground lines? Maybe they are logic-lows?

 

With regard to your digital sequences: Are there pauses with each hyphenated segment? Any other such clues to the data stream may help make some more sense of it?

 

Still, it doesn't make sense why a track-up would generate a different signal for odd-to-even track changes vs even-to-odd transitions...

Mkay...pin 7 is in either of two states at any time. Either it is constant low (no signal), or it's a steady signal, in 5ms timing, it would be 11000000, or 10ms high, & 30ms low. The state changes every time a command is sent (assumed) on this pin. So, one command starts at the end of 30ms low and ends either low, or with a single 1 (the parity bit). The other starts by itself (no other signal running), and ends with the start of the 10/30 signal. I was hoping to see a single command sent on this pin, so I didn't bother trying to figure out two pins at once, but after translating into dec10, I'd tend to agree with you & think it might be sending until it receives a response...I will have to check that later - a logic analyser would help I'll post some image captures of the signal so you can "see" what I'm talking about..

Yes, I monitored the other lines while changing tracks, turning on & off the stereo and while changing from CD to FM&AM. They seem constant. I'm agree, there seems an aweful lot of them though!

With regard to your digital sequences: Are there pauses with each hyphenated segment? Any other such clues to the data stream may help make some more sense of it?

 

Still, it doesn't make sense why a track-up would generate a different signal for odd-to-even track changes vs even-to-odd transitions...

The different signals have me baffled as well. There's no pauses, the hyphens are simply to make it easier to read...dividing the stream into 4 bit nibbles. I'll play with recording both signals simultaneously tonight & see if there's anything else to help make sense of it.

Well, I updated 8 to 9 data. To give you some idea what I'm lookin at...here are plots of 8 to 9, one with the 10/30 signal before, and one with the 10/30 signal after. (edit) Red is pin 6 BTW, blue is pin 7.

I also recorded a few other functions, but without some better understanding of what's going on, I'm probably going to be quickly overwhelmed with data...I need to figure out why it's using different signals to accomplish the same thing.

Would someone who's installed Jazzy's mod in their U.S. Spec.B radio be willing to post or PM me photos of the job? I'm especially interested in how the climate controls complicate the install, and how the navigation system hooks into the radio.

 

thanks....

 

I installed it a couple of weeks ago in my spec. B. This guy is a lifesaver as I have an iPod and SIRIUS. I was not skeptical with the product or concerned with installation. Just get it. I rate his instructions w/ pics. A+, and they are photocopies. Your stated concerns are not relavent, believe me. The NAV and climate controls are individual, unique plugs. Give yourself a 2-3 hour window, follow the instructions and take your time.

How did you go about hooking up both your iPod and Sirius? I'm in the same boat and was just planning on leaving the iPod out of th equation since I listen to Sirius 99% of the time. But, I know there will be times where I'm just dying to hear one particular song and I'd prefer to not have to go back to FM modulation if I can avoid it.

 

(sorry if this has already been answered...I didn't want to go back through 50+ pages and you can imagine what search results returned)

Basically, you'll need two all-female RCA y-adapters, in addition to a few other wires, which will come into play after the ground loop interupt(<<<<highly recommended) giving you two sets of RCA inputs.

 

I am going to post some pics of my setup later with comments on how I wired mine up.

Just a plug for Jazzy, for any skeptics.

 

Wiring is as follows:

 

from Aux Board---Mini Stereo Ext. Cable

to Mini Stereo Plug to RCA Jack Splitter

to L/R RCA Cable as short as possible

to Ground Loop Interrupt

to L/R RCA Cable

to (2) All Female RCA Splitters

to

(1) L/R RCA Cable to SIRIUS Tuner under passenger seat.

(1) Y Audio Cable (it begins w/ L/R RCA and ends in stereo mini for iPod)

 

Hope this helps anyone who needs it. Very happy with this setup.

This is a slick setup, Scoobydew.

 

What material did you use to fill the space in your ashtray for your satellite radio system?

 

The red seats and red trim are killer.

I used a greyish-black picture framing matte (followed by a thin and fairly soft piece of sheet metal underneath for support).

Also, instead of trying to cut out an opening, I mounted the controller bracket on top of the above assembly. ^^^

What happens when CD is pressed twice? I was thinking about that as I drove home and cycled through FM1 and FM2. Seems like they might do the same for CD1-6 in the Dash and CD's 1-6 in a changer somewhere.

Nothing happens...at least, nothing on pin 7.

 

Thanks for the info scoobydrew. I was sure someone had tried this in a SpecB, but I couldn't remember who. Looks like a pretty sweet setup.

 

So, I've been looking at the signals on pin 6 some... Not easy to make heads or tails of, but I've been trying to figure out if there's some kind of marker to indicate the start and end of a data stream. The best I can determine... which admittedly, isn't great... it seems to be 230ms chunks, which at 5ms timing is 46 bits. The start (or end) of each string seems to be marked by 10ms high followed by 20ms low. Just to make things more confusing, when the 10/30 signal is "on" active on pin 7, the divider seems to be 10ms low followed by 20ms high instead.

 

That leaves 200ms for data, or 40 bits... 10 nibbles. I'll collect some data later & see if I can make some sense of that instead...

Just wanted to drop a follow-up that I installed the Jazzy board and a GLI in my Outback XT this weekend and I NO LONGER AM SEARCHING FOR FREE FM frequencies while on the road and the sound improvement is fantastic.

 

Thanks for your efforts!

 

Looking forward to ditching the blank CD

 

Thanks,

 

Jed

Keep up the good work Jazzy! I'd be into upgrading too.

Mine sounds fantastic. Thanks Jazzy!

Well, now that I have my LGT, it is time for my Jazzy board. Jazzy, do you have the pro install kit avaiable on your website or just as paypal?

 

Thanks,

 

Ben

Thanks,

 

Ben

As a kit, it's only available on the forum. You can buy all the components on the website though. I should mention I'm out of GLI's, but I have more on the way that should be here Monday. I also removed free shipping, which upped the total price $5.

 

And thanks for the continued feedback everyone. It never gets old hearing about successful installs

Jazzy, thanks for the fast feedback. I will proball be ordering it monday or so anyway. I was just thinking that it would be easier for me to just get the kit, so expect it to come through sometime between now and tuesday. The FM transmitter in the myfi2 is just not adiquate for my tast.

 

Ben

Just ordered mine. Can't wait.
