Does anyone know where I can find the CD for this? I know each is for certain regions, but im looking for one for California.

 

The 2003 nav system is bad enough that it really isn't worth spending much money on the CD. The unit on my 2003 S500 can't read a CD and can't eject - but I have no plans to try to repair or replace it. I just use Google maps...

That being said, you might be able to find a single disk on eBay, or even perhaps on a local Craigslist.

 

the CD on my mom's unit takes and eject's CD's. So going by that, seems that it works. I'll try it out and report my findings, Thanks for the suggestion.

 

just because it loads and ejects doesn’t mean it works . The nav cd slot only reads nav cds and cannot play music cds . The music cds only work in the trunk cd changer

In fact many nav cd slots are left empty on purpose , because the nav system has an issue where it fails to go to sleep when the car is turned off , and drains the battery

 

You know what, I just forgot about the rear CD changer. Regardless that hasnt been an issue either (The front CD changer)

 

You know 2003 has female av in in glove box. Wasn’t in manual. Wish I’d known past loads of years lol
Headset SYS
Choose Aux.
I use male to male and tiny Bluetooth receiver.
i believe only found in 2003. Not any other year

 

The jack in the 2003 glove box is for Audio only - no connection with nav CD.

 

agreed. Was a side note. When see 2003 audio/nav feel need to share in case.
Soo much better than having get one of refurb expensive Bluetooth things replace phone. Also jack equals no steering wheel inputs or two way. Does intergrate re iPhone dimms music playing when maps pops up instructions!!
Still great find for me.
you have a great one.

 

Yes, the single-year, hidden audio jack is one of the W220's better-hidden secrets. To me anyway, the only thing that makes it worthwhile is voice control of the phone. Far too distracting to be fiddling with trying to get the music you want otherwise.

Now, if we could just find a way to merge the phone nav system with COMAND...

 

Fat chance!!!

 

arguably the best part of the car, yes, but the problem is you need a long enough cable.
