Already tried emailing bob at modifry but im assuming he's probably still busy from his move. So maybe you guys could help me out. It was the coolest item when it was working but now driving me nuts. I took out my deck now at least several times searching for any strain on the wiring or cuts. Which there were none. Remote wire is plugged in firmly and electrical tapped. All wires are soddered.

I Purchased a wired dci for my JVC KD-AVX11 deck.
I had a Modifry DCI working great for about a year and all the sudden one day it started to do wierd stuff. I notice though that my mute button is always working flawlessly though. I started to notice when I would volume up it would sometimes do the CH command or will not respond to the volume up or down. So I took out my deck and checked the wires all looked well. I contacted bob the first time and was able to send it in for repairs. Bob found that it may have needed an update on the modifry itself so he did and said everything was working well.

So I just recently received back the modifry. I plugged it in and now nothing works besides the mute button? Big circle button does nothing, ch does nothing volume does nothing. The only thing i can think of now is to purchase a new one (which im not sure if I want to spend another 90 bucks since it would cost almost as much as my JVC deck) or find an s2k member who would be willing to plug in the modifry to there car. I have already removed my deck again and removed all electrical tape and found all my wires are still soddered together no strain or cuts on the harness at all that i can see. Remote wire definately plugged and clicked it and re-electrical tapped. Im really stuck. I also have done a search and tried to reset my deck and then start the car with the same results only mute button works. Thanks for the help folks!

 

I have an AVX44 with the same wired DCI, and noticed a few times it would give me weird commands. Restarting the car would fix it, but since you already tried all that, I am at a loss as to how to fix it. Maybe the toggle switches on the board got moved or are not set for your deck? Have you tried verifying they are fully seated in their on or off positions? Other than that I'm not sure what you could try. I bet Bob gets back to you - he is great about working tech issues with folks. I'd offer to try it on my deck, but I am stationed in Germany, so you would get a faster turnaround time with Bob himself. Good luck.

 

yea i'd check toggle switches

 

Thanks for the reply's. I definately played with the dip switches and they are definately clicked in the correct place. Just wanted to make sure I tried most of the stuff. Ill just probably have to wait for Bob's reply then. Hopefully i can finally get this thing working again.

 

if you have a multimeter, you can troubleshoot everything external to
the DCI following Bob's tech page. If all the wiring checks out, it's either
the DCI or the headunit.

 

i had a similar problem it was the DCI just try emailing bob again and be patient he will take care of you

 

Thanks again for your guy's suggestions. I got a volt meter and have no idea on what the different toggle settings are on this thing so left it at 10 DCV. Now I hope some of you guys know how to read this cause i dont but i can definately say the wires appear to be good. I really think its the DCI now. Let me know how you guys feel or think. I also did speak with Bob already but told me to do the following:

"Do this test - put in a CD, wait till it starts playing and then press MUTE. Does the CD pause and volume turn completely off or is the CD still playing? You might have to mute it a couple times to be sure the CD is pausing and then resuming exactly where it left off (or not).

If it does not pause then the mute command is going to the HU on the 3.5mm cable, which means the DCI is working and the cable is good. If this is the case then the problem must be that the DCI does not see the dash switch commands and there must be an issue with the dash switch wire (green wire on DCI harness).

If the mute test DID pause the CD playback then the mute command is going to the HU on the DCI blue wire (ATT wire), which could mean the problem is the 3.5mm cable is bad or not making a good connection. Usually cable problems are at the DCI harness side - one of the little wires in the 3.5mm cable may get broken where it enters the DCI connector."

Now It does not pause. It does mute properly so I checked the green wire. Even cut off the soddering point and re-soddered it back. I think this is like my 6th time now taking out the deck and checking the wires.... So frustrating. So i finally got a buddy of mine to give me a volt meter hopefully you guys can read this better than i can. I am definately not an electronics major but i can definately say i got a pretty good idea what each wire powers up. But from what i can tell the wiring looks fine.

Here are the pictures.

This is the meter i Used kinda old school but as long as it works right??


Green wire test



Grey wire not plugged in and the other third notch not tested assuming negative for remote wire

Remote wire positive test



Black wire negative so of course 0

Red wire postive test



Blue wire test. Deck had to be on to get reading



Purple wire test. In order to get reading had to hit the mute button

 

I just emailed bob this post hopefully I can get this fixed. Just really getting frustrated trying to figure it out.

 

OK, we have some progress. The voltage on the green wire looks correct (about 4.5 volts when no buttons are pressed). While it would be interesting to see if the voltage changed to the correct reading for each dash button I don't think it's worth the effort. My guess is the DCI is processing the mute command signal but not the dash switch signals, which is a pretty unusual type of failure.

Send the bugger back to me and I'll ship you a new one (send just the DCI, leave the wiring intact). Please use the below address to return the item, and be sure to package it appropriately, not like these guys

When you re-install it, why don't you put the DCI somewhere more accessible, like behind one of the console side panels or under the dash near the radio console. That way you can get to it without taking the HU out if you want to change the settings or need to troubleshoot it again. (this is suggested in the manual)

 

You know the crazy part is i didnt know i could test it directly from the modifry harness itself but saw metal i can use to touch with the voltmeter. I really didnt have to take out my deck the last other time but really needed to check for strain on the green wire. Made me feel kinda duh when i realized i didnt have to since i had the voltmeter.... I would definately tried to test it again but i had to give back the voltmeter to my friend. Thanks for the reply they don't lie when they say you will take care of your customers. I'll be sending it to you! Thanks BOB!!!
