2003 SL500
Upgrade 2003 SL500 Radio
All - I've spent days searching for an aftermarket alternative to the stock nav / radio in my 2003 SL500. I do not want to modify / cut the trim in any way. It appears the upgrades drive several requirements - a separate fascia plate and harnesses that allow the new radio to communicate properly. I'm like an Apple Carplay unit that allows me to simply plug my iPhone into a accessory or charging cable and utilize the apps loaded on my phone, including my navigation apps (Waze). I'm also looking for a vendor that can properly install the new system as well.
Any suggestions?

I'm in the process of making this changes and will create a post when I'm done next week but I used the Spiral Audio harness and dash kit. I have a 2009 SL550.

Be aware that the '03 and '04 have a different fiber optic system and no aftermarket solutions exist for a plug and play solution. You will need to replace the amp at a minimum. Also, I'm not sure that you can find a bezel that fits within the wood trim. You might need to cut off the upper portion for it to fit. '05 and up have a wider bezel and the wood trim ends at the bottom of the radio instead of wrapping around it. I have a bezel and a trimmed piece of console trim that I removed to put a stock radio back in (previous owner had converted, but sold it with the radio removed). PM me if you are interested.

If you use an aftermarket amplifier be aware that there is no crossover on the tweeter to protect it from lower frequencies. (It isn't needed with the stock amp since it has its own dedicated amplifier.) To prevent the tweeter from running hot and potential damage you ought to put a capacitor in series with one of the two wires going to it.

All,
Last week I had my Comand unit replaced with a JVC unit with Apple CarPlay and numerous other 21st century features that did not exist in my 18 year old SL 500. I could not be happier. I lost the ability to change the volume on the steering wheel but that was a small trade off for the array of features I gained from the transformation. It’s like night and day. My 2003 MB now seems current.
Also, I had an Alpine amplifier installed to drive the subwoofer and center channels. Initially I was going to do the install myself to save money but after buying the head unit and amplifier from Best Buy i was convinced to at least consider their installation guy to install the units as they do installation free if you purchase the hardware from them.
I went into installation day with a pessimist approach but after spending 20-30 minutes with the tech I decided to move forward with the install. He let me know that if I was not 100% satisfied with his work he would reinstall my MB system and give me a full return on the equipment that I purchased from Best Buy if I wanted. He said he had performed roughly 40 Mercedes installs in his 14 years at Best Buy which is a big reason I moved forward.
The sound is not 100% of what the Bose system delivered before but it is dammed close. If Bose system is a 10 the new system is a 9. The install tech also said that I could achieve even better sound if I replace the current door speakers which Best Buy will install for nothing if I buy from them. I’ll likely be doing that soon and would have done it the same day if time would have permitted.
Bottom line is, don’t be afraid to make the transformation from the archaic Bose/Command system if you have a good installation technician. I was told several times to not let someone mess with my Comand system as ‘you’ll be sorry for it’ which is why I was so cautious to make the change. However, after my wife aid “either get a radio that I can take calls on or get me a new car” I decided it was worth the chance. Can’t tell you how happy we both are.
BTW, my total cost for the transformation was roughly $500. So far it’s the best half a grand I’ve spent on this car.
Good Luck!

1. Do they have the bezel to fit the JVC unit?
2. How about the microphone for cellphone (airplay or car play)? do they have to install a new microphone?
3. Did you have a backup camera install? do they sell that at BB?

If all you wanted was phone call interactivity then just put the official Mercedes “Puck” in the armrest and the factory system does the rest. It’s all prewired and the factory microphone is good.
If you want Bluetooth connectivity for your phone to play music just get a Dension system to replace the CD Changer in the rear locker. Everything else stays stock, looks original, Steering Wheel Controls stay the same, linguatronic commands still work and you keep the Bose quality.

LanceDal,
1. I used a model specific, double DIN bezel from Spiral Audio. It looks very factory. I'll attach a photo.
2. We used the microphone that came with the JVC unit. Photo attached.
3. Didn't do the backup camera yet. Going to do it later. Install guy has done them but significant job with the way the trunk and roof move so much during operation.
Hope that helps.
It's between the dials in front of the dimmer for the instrument panel.

Did your BB technician tell you what speakers he would replace them with? I thought you could only get the factory speakers that fit in the door.

Also, if you have not done it already, you can change your clock so that it is set-able from the steering wheel buttons (as you no longer have the head unit controlling that). Its been a few years since I did this, but I am pretty sure these are the instructions I used ...
(The following will enable you to set the hours/minutes in the menu where you normally can only shift between 12H/24H formats)
You need Star with Developer mode
Go to:
"Control units"
"Information and communication"
"ICM - Instument cluster with maintenance interval display"
"Diagnosis to plant specifications"
"Control unit adaptations"
"Control unit adaptations (variant coding)"
"Variantenkodierung Werkseinstellungen"
Scroll down and set "Uhrenverstellung" to "enable"
hope that helps,
Chris

Have your install guy add the Metra Axxess ASWC-1 and you will be able to raise and lower the volume AND answer/make calls (as well as turn on the voice control features of your new head unit) with the 4 right side buttons. I have been using this set-up on my 2003 SL55 and it works great.

I went with the Spiral Audio double DIN bezel for a custom fit/look. Inside is a JVC KW-M750BT head unit with an Alpine 4 Channel Amp (Don't remember the model number but it wasn't the most elaborate one they offered). Purchased the antenna adapter to utilize the factory radio antenna and it works just fine. Also had to purchase some "Speed" cable to get the wiring from the head uint to the speaker hub location behind the driver's seat and some RCA cable to get signal from head unit to the new amplifier.
Hope that helps. I really like my new system.

Really appreciate the answers. Have you asked about a wireless back up camera to integrate? They even have solar frames to power the camera. Thx

I have not asked about wireless system. I will look into it before doing anything. There is a "bullet" style camera that my installation guy is recommending that goes on the bottom of the rear bumper that is fairly easy to install, unobtrusive, and apparently works quite well that I will likely go with given the JVC unit has a video input ready to accept the signal.
