Does anyone know if these radios can still be decoded and used? I did a little searching, and it appears for this model head unit the "Hold 1 and 6" trick does not give the reference numbers that you can then give to Honda and ask them to look up the code. I've also read that Honda deleted/purged their old data for these radios anyway.

So if one doesn't have the code written down, is the radio a paperweight? I was hoping to do a "period-correct" restoration on my EF hatch using OEM parts when I could, and I have a 3000 series Radio with the add-on CD player for the lower optional console which I'm wanting to install.

Not sure if anyone has ever tried, or cared enough to figure out a way to internally bypass (or somehow reset/input a new code). I'm sure there's got to be a way, kind of like hacking/rooting a cell phone in developer settings if you can get inside the rudimentary BIOS system of the radio (if it even has that, I'm not sure what makes it "run" so to speak). Or maybe it's a matter of figuring out which chip on the board stores the reset code, then replace that chip with one from a broken radio with a known code. I don't know, I guess I'm just thinking as I type. But if anyone has any ideas on how to make this radio come back to life, I'd love to learn more.

 

you can also give honda the serial number that should be on a sticker on the radio deck
in order to get the code

also there is a website with the serial numbers and codes
i found it years ago when looking for a code for a toyota but all the honda ones were on there also
you can search for it on google it might take a while to find but youll find it ^_-

honda radio codes

 

So today I took the physical head unit to my local Honda dealer, and both the lady in the service department and the parts manager tried looking up the code based on the serial number printed on the label; no luck.

They referred me to Honda's customer care hotline; which I tried, but they were even less helpful (basically advised me to swap in a modern radio,...I dont wanna do that; I guess they dont understand "period correct" restorations).

I'm not gonna give up, I know there has to be a way to unlock it.

In other news, after I got talking to the parts manager about my obsession with older Hondas, he offered me what he calls his "dead stock" of radios he hasn't been able to sell. So I now have 10 NIB Honda radios that I dont know what to do with LOL, but at less than $10/each, I couldn't pass them up.

 

Did you happen to have an EG or DC integra stereo?

 

I have this for an EG.

 

I also have this used Honda 2000 series EG radio (3rd down from top on right side); and an unknown Acura CD player (bottom of right side). Both units however are untested, and unknown if a code is needed (I can attempt to test them in my EF if you think you might be interested in one/both).

 

The bottom right appears to be a integra . Cool collection, I like the one with the yellow writing.

 

Yes definitely interested. Send me a PM with what you're asking for the 2 EG stereos receivers and the Acura CD stereo receiver. I've always wanted a clean stock radio for my cars.

 

Today I was able to get into my Honda 3000 head unit.

I learned that there were two main ways manufacturers set radio codes back then; there's likely more ways it's done today, but for late 80s early 90s it was done one of two ways:

1. eeprom chips. Basically a memory chip, where the code is stored. If a radio has an eeprom chip, its possible to reset the code one of two ways: send to someone with an eeprom reader/writer; or replace the eeprom chip with that of a known code. The 3000 series does not use this method; so lets move on.

2. Circuit board jumpers. This was the method Clarion used for the 3000 series. Basically "all" 3000 series radios are the same, with the exception of certain soldered or non-soldered jumper slots on the circuit board. There is a series of 6 slots, 1-6 from right to left. If you obtain a known code from a known radio, and know the jumper sequence (open or closed) you can resolder your radio to that sequence, and that code is now your code.

That's what I did. I was fortunate enough to find a fellow Honda 3000 radio owner, who shared his radio's jumper sequence and code with me, now my radio shares his radio's code.

Here's a pic of the jumper sequence for a visual of what I'm talking about. It's very simple to access, just take off a handful of screws to remove the back plate, and you're presented with the underside of the circuit board. Then the jumpers are right there.

If anyone has a codeless Honda 3000, and needs the code, please PM and I will be happy to share the solder sequence and code.

 

Hi, I'm in the process of buying a Honda 3000 and will be soldering the jumpers manually to enter the code. Can you post which code and sequence ended up working for you? Thanks!
