Our chinese unit in ML is having the same issue. Looks like a very common problem reusing factory Mercedes antenna.

Is there a best practice to address the complex antenna and amp configuration for aftermarket radios? Lots of posts, but nothing jumps out as being the most straight forward fix.

Success rate for this swap and for that matter any other audio modification must be very low. I’m yet to see a happy customer after the “upgrade”.
Myself I’m not that concerned on where the unit is made since most of them are now made in the same country anyway. Previous owner of my Sl spent a pretty penny on the radio swap/upgrade by installing a Pioneer unit in the reputable audio shop. Reception is like the wind, it comes and goes. Most importantly steering wheel controls aren’t working. Do I need to go on? As the looks go personally I have nothing against the unit but in this car it just looks out of place.
To sum it all up - I would love to put all back, jut the way it was.

I upgraded my 2003 Sl55’s radio with an Android unit. Tried everything under the sun (aside from opening up the circuit board) to get better radio reception with zero success. I gave up and just use the local station or mostly use Pandora from my phone or listen to music I have stored on the sd card inside the radio. Overall it is a huge improvement over the stock radio since I now have Bluetooth capability... much better navigation, etc.

The Metra steering wheel control adapter would definitely fix the steering wheel controls. Your install looks pretty good and probably already has it. If not, it would be very easy to install and would definitely fix the SWC issue. Here is a link: https://axxessinterfaces.com/product...s-instructions

What year is your SL? If 2007 or 2008, perhaps the NAV-TV kit would help to convert it to work with the MOST interface? I am trying to decide what to do for a 2007 SL55, and this fiber conversion kit seems like a good idea. I am trying to decide between the Seicane and Alpine, but based on what I am reading the Alpine seems like a safer bet.

I actually don’t have an SL. I have been planning to purchase one and wanted to know what I would do in regards to audio at time of purchase.

Wow sweet CL! I have a 600. I am looking to do the same with my 2003 SL and CL. Yes I'm nuts. Bought a SL55 but can't bring myself to sell the CL. Love long distance trips in it. Like an airplane. I have been reading that there is an "adapter" that plugs into our optical outputs on the 2003 models. There is a newer post about it. Some posted THESE or THESE

You need a lot more than just center trim. 03 SL uses a proprietary fiber optic loop whereas from 05+ they switch to MOST fiber optic loop. This means you will need to replace your head unit, amp, and wiring.

I have a full MOST wiring harness, just trying to determine if it's worth the hassle of an upgrade.

2004 AMG SL55
I am looking to upgrade my 2004 SL55 head unit as well. After emailing customer service at Seicane they request I check to see if I have built in amp or not. They offer an additional cable if no amp. The rest they promise is plug and play with steering wheel controls working. I don't want to have my dash apart for weeks waiting on cables or amps.
Does anybody know if my car has built in amp? Audio system currently is as how it left factory. Thanks for any insight.

I just bought the unit from seicane, thy ask for a picture of your radio and dash when you order and they determine what you need, they send me the radio with a 6m wireharness that plugs into the bose AMP.

The audio input to the Bose amplifier is light instead of electricity. I presume that harness plugs into the existing Bose amplifier connector and bypasses the Bose.

Please let me know how you make out with it. What year is yours? I have seen articles saying 2005 have a different fiber optic amp than the 2004.
I send Seicane a picture of dash and stock radio and they still didn’t know if I needed that extra cable.

Since 2018 my SL55 has the Android HU and I've been using it for a while. I have replaced the Bose amp with a 4x100W Pioneer that is connected to the doors and the subwoofer and the front center and the rear spekers is connected to the HU built amplifier, the sond is as good as with the std Bose setup.
Reception is OK, when close to the transmitters but not as good as the Comand but acceptable. I noticed that the stations are not updated when listening to other media when driving long distance, might be a setting thing I've missed.
The screen is washed out by the sun in the same way as the Comand HU when the top is down, I have fitted anti-glare film as the high gloss screen is like a mirror when the sun hit it. The screen contrast should be much brighter to work perfekt when the top is down, but as referenceI have compared with a Samsung Galaxy Tab7" and a Chines Android tablet and they don't have better contrast.
The steering wheel buttons works as before ((if the control box is set to S-Class on my 2003) when changing menues the station also changes, same on media when changing tunes and the same if you change menues the station or tune changes.
The phone buttons works perfect and the sound is quite good in both directions.
I have also installed reverse camera, a wirless one, that s fitted in the possition where the right licence plate light is, it works perpekt.
So how is the verdict?
The only remark I have is that the start up time is to long, 30-60 seconds, but when it is up running it is great and for less then €500 I have as modern system in a 16 year old car with dual USB as you get when buying a new car.

Does reverse camera display come on automatically when car placed in R, or do you have to switch display?
thanks again

Automatically using the can bus module. The radio also has an extra reverse input wire if you are omitting the can module and still want it to switch to the camera when backing up.

Hey guys, I have a 2003 sl500 , I purchased the seicane unit and it came with the 6m long cable , but i do not see how this unit is plug and play , the connectors from the car dont match the ones that seicane sent , and the plugs that are supposed to be plugged into the wireloom in the back and bypass the amp seem to be different as well.

Which CAN bus module do you have? I have an Axxess ASWC-1 steering wheel interface module connected to a Kenwood Ecxelon DMX905S. I haven't installed a backup camera yet, but it would be great to know the steering wheel interface module will send a reverse signal to the head unit versus having to hardwire it.

Center fill speaker

My 04 SL55 does have the fiber optic amp which I will have to replace

does anyone know of an amp that has a center full channel? Wasn’t planning on replacing speakers. The dash speaker is a center fill that apparently is a blend of left and right

GPS antenna

Did you use supplied GPS antenna? The factory connection looks similar but the Chinese help line suggested using the supplies one. I was considering putting supplied one in hood vent above battery then running wire through dash etc. but if factory gps antenna works it would save a lot of work
