I'm in the process of finishing up my Eonon GA9301B (A0582 wiring harness) install. Everything works great, I also installed a backup camera with mine and got it working too, had to excite a wire on the CanBus adapter to get it to work correctly but not a big deal. I wasn't happy with the built in AM/FM antenna and the separate WiFi and GPS antennas so I bought a shark fin antenna that has AM/FM, WiFi, GPS and LTE antennas. Haven't decided on which LTE booster (amplifier) to use yet but it will go where the old CD changer was. Also adding a 12v USB hub so I don't have to use the 2 loose USB adapters.
Can you elaborate on the backup camera wiring hiccup? Which sharkfin antenna did you go with? I am a newbie when it comes to electronics so i am hoping to replicate someone else's success...thanks!

With the backup camera hooked up I was not getting an image on the head unit when I engaged reverse. I looked at the wiring diagram and saw pin 6 on the back of the head unit was labeled 'rearview control wire'. On the A0582 wiring harness, that wire was controlled by the CanBus adapter. I just ran a jumper wire from my backup lights to that wire and it worked. I'm assuming that any vehicle that came from the factory with a backup camera wouldn't need this modification and it would already be getting the signal from the CanBus.

Shark fin antenna link. You will have to specify which 4 antenna leads you want and what connectors you want on them. DAB is for digital audio broadcast, a standard that is used in Europe but not the US, here we use HD radio instead. If you need more information PM me your email address and I'll forward the email I sent to the factory specifying what I needed.

Do you still have the hands free phone function ? can the vehicle still transfer your calls via the new stereo like it did with the old unit? does your new stereo allow for hands free calling via your stereo screen?

My 2004 did not have bluetooth from the factory. My Eonon does have hands free bluetooth. My steering wheel does not have the 'phone' button, but all the buttons used to control the factory stereo function correctly with the Eonon. The radio also has streaming bluetooth so I can play music off my phone without having to connect to the radio USB port.

Thanks Rattler, MrE and the others for your informative posts. I have a Dynavin in Rover 2, but Rover 1's BM54 just died due to water ingress, so I decided it was time to do an upgrade. The new Dynavin N7 is overpriced for what it is, so I just picked up the Eonon GA9201A with an A0582 harness, which I'm hoping will work fine.

My first question is: seeing from Rattler's pictures of how the harness plugs into the existing BM54, do you need to have a fully functioning BM54 for the EONON to function correctly? Or can the Eonon work without a BM54 even present?

I'm also planning on wiring up a rear reverse camera in addition to a front bumper cam.

Lastly, I'm an audiophile and have another life in home Hi-Fi, building speakers and such. So I have enormous respect for Harman and the work Dr. Floyd Toole has done in quantifying loudspekaer measurements. I'm also impressed by the work Harman did on the Logic 7, I think the factory amp and DSP setup sounds great in the car and I wish to keep every aspect of it. I want to keep the DSP and ensure that the Eonon uses the Logic 7. Any further tips on interfacing on the Logic 7 would be appreciated.

Thanks in advance

Quick update. I have the Logic 7 and it worked fine with the amp and everything, which was one of my initial concerns as well. Everything is still working fine. I'm not 100% sure about the new models offered, but I'd just see what the old models were updated to and get one of those. Make sure you get the wiring harness. I don't have the backup camera...

Everything is still working fine.

The only thing I have a slight problem with is on really bright days it's a little difficult to see the map if I'm driving. I haven't changed any of the default settings, there may be a way to adjust this...

You will need a functioning BM54 for it to work.

With the GA9301B they added a 'DIM' button for adjusting the display brightness, you should be able to adjust yours through settings.

rattler1975 and MrE, thanks again for your replies.

Eonon contact me and noted that GA9201A was out of stock, but their replacement model is GA9201B. Among some of the changes, GA9201B no longer has the EONON logo on the front, so it can blend it better with the rest of the dash. They are sending it with an A0582 harness. I can't wait to install it!

Congratulations, you'll be happy you did. Just as a FYI, I found a keyboard very helpful in setting mine up, either USB or Bluetooth.

MrE - would it be possible to show how you made the reverse camera work? I just got done installing the Eonon GA9301B in the dash and will be tackling the wiring later on. I did purchase the backup camera and would very much like it to work. Do you have any additional notes on the camera install? Thanks!

I used a wire tap on the hot lead to the backup lights for power to the backup camera and to the A0582 harness where you plug the Can Bus decoder that comes with the GA9301B. Tap into the the same color wire that goes to pin 6 (rearview control wire) of the GA9301B.

I am in the process of installing this into my 2003 Range Rover G4 and I am stuck - I wired everything up and before running the A0582 harness from back to front, I decided to plug in the head unit just to make sure everything is working. It's not. The head unit powers on but I am getting zero sound. The radio also failed to pick up any station while auto scanning. Am I doing something wrong? Here are some pictures of my install so far.

A0582 plug into stock BM54 radio and the stock BM54 harness is plugged into A0582

Unplugged radio antenna from BM54 into A0582 radio jack

Plug A0582 into Eonon Canbus decoder that came with the Eonon unit. When I plugged this in, the lights in the car would turn on (I did not disconnect battery).

The front end of A0582 plugged into Eonon unit. It powers up but there is no sound at all and doesn't seem like it's picking up any radio stations. Bluetooth connects from my phone to Eonon but again no sound when playing music.

I did not connect the center speaker on top of the dash. What am I doing wrong???

Hi.
I am having a similar situation here, with rear view camera.
So, you have just used a backlight as a CAN 'signal', right?
Where did you spliced in?

Tnx in advance?

Looks like you're missing all the speaker wires where you're plugged into the BM54. You need to grab them from the original BM54 plug, the way you have them running into the A0582 harness they not connected to wires. I tried to get a decent picture of mine, but the interior is all assembled now. They're two plugs, one white and the other is black.

It also appears that you're using the can bus decoder hooked to either the BMW E46/E39 (A) or the BMW E46/E39 (B) adapter that ships with the radio. They're not used, you have a plug on the A0582 harness for the can bus decoder.

I spliced in in the trunk area where the can bus decoder plugs into the wiring harness. You can use the unused adapters that shipped with the radio to figure out which wire. On my new harness it was an orange wire that went to pin six, but both the unused adapters have a brown wire running to pin six.

The speaker wires, the black and white plug is plugged into the A0582 adapter and the canbus decoder is also plugged into the A0582. I reconnected everything and was able to get bluetooth music for about 20 seconds before the music went away again. Starting to question the integrity of the harness...I've sent an email to Eonon and hoping to get a response.

However, still no radio signal and it doesn't pick up any stations at all. Again, I plugged the radio antenna from the BM54 into the A0582 radio jack...that should be the way to do it right? I thought perhaps I had blown a radio fuse but when I plugged in the factory unit, everything works. So puzzled and kinda frustrated...I thought this was a simple PnP set up!

They have to be plugged into the A0582 adapter where it plugs into the BM54. The instructions are weak at best, I made the same mistake. My car had an aftermarket XM adapter that used the stock AM/FM antenna. No matter how I plugged it into the A0582 harness I was only able to receive poor to mediocre AM/FM signal, that's why I went to the aftermarket shark fin antenna.

Hi all,
Thanks rattler for this great photo-reportage.
I plan on doing the same with my '2004 L322 Vogue.

First, I have to check what kind of modules I have at the back of the truck.
I sure have a GPS module. I also have a power amplifier and I seem to have an aerial amplifier.

I have not yet seen the BM54 module. Is it hidden under the plastic cover, next to the amplifier ?
