SL/R230: Hi, new owner. 2007 SL550

I bought a 2007 SL550 with AMG sport option and, well, I think every other option as well.
94k mi. a 'white' ABC malfunction showing on the multifunction display. Keyless Go is not working. Not sure if it is the key (I only have one) or the car. Otherwise seems to be in really good condition.
I'd like to get a backup key (or a primary key, if getting a Keyless-Go enabled key is the solution). Suggestions for the best dealer in Dallas for this is appreciated.
Anyone in the Metroplex with a SDS and willing to hook it up to my car.. multiple cold beverages of your choosing??
First question: I have seen a few posts indicating that a 2007 SL550 has bluetooth capability. I am not finding any evidence of that in my car. Is it because I have the "Premium Sound" option? What should I be looking for? OK, first 2 questions...
Thanks to moderators and contributors for the fire-hose-stream of useful information here.
The DVD slot above the Comand display promptly ate the first MP3 CD I put in. First it declared the format to be wrong (could be, it was my first attempt at a MP3 CD. Any Windows 10 suggestions welcome). Then it said it was ejecting it when I pushed the button. Then it declared there was no disk present, although it had not ejected one. I removed the in-dash unit, removed the optical drive module (with my CD still in its maw), read the part number on the label, and ordered a replacement from China. Fingers crossed.
My advice is to buy your own SDS. You can get a full turnkey system pre-installed on a used laptop for about $300. Bobterry999 has posted a few links for these. You can use this to diagnose your ABC issues. Also, this is an invaluable ABC resource:

As for KeylessGo, so it does not work at all? What messages are displayed on the MFD when you try to use it? Also, try from the passenger door and trunk to rule out antenna issues. Check fuse 58 on the rear panel, too. Most dealers charge the same for keys and now require the car to be in service for programming. With KeylessGo, there is some programming required. Expect prices over $400. Although it is possible to order a non-KeylessGo key, most parts guys don't know how to do that, so by default they order the proper KeylessGo version.
Bluetooth was not standard equipment until the MY2009 refresh where they upgraded the COMAND head unit to the NTG 2.5 version. With your COMAND unit, there is no good way to do streaming music, but you can do hands-free if the car has the optional cell phone interface. If so, there will be a puck or at least an MHI plug in the center console for this. If not, then forget it - it's very expensive to retrofit. If you do have the MHI connector, then you will need the Bluetooth puck. MBZ makes one as does a company called Viseeo.
My datacard says I have option 389 - MOBILE PRE.-INSTALLATION (MTUS) USA/CANADA COMPL. I took a closer look in the center console, and found the phone interface. Lucky me.

maybe i'll just get the whole out of the box turn key system and not mess with looking for parts to put together.

If you want to buy a complete setup I will sell you my Star Diagnosis kit for $500, and I pay the shipping. (I'd then immediately purchase for $249 the aliexpress.com kit and look for a Dell on eBay.)

can you tell me a bit more about your setup?
basically i would receive everything in the mail that i can just plug-n-play with my MB? all cables and everything?
what's the software version you have?
My software is from mid-2014. This is the latest version of software which is fully supported by the C3 multiplexer. (The eBay seller tacitly recognizes the limitations of using his kit with a newer vehicle as evidenced by the cautionary note at the bottom of his ad.) If you want a kit which will work with all Mercedes cars which have been produced since late 2014, then you need a "C4" or newer version of multiplexer.
If you still want mine instead of the aliexpress.com kit, then I suggest we work out further details via PM.
It also says it has comm errors with both Keyless go (no surprise, it's not working) and ABC. The latter is a little surprising, since it does seem to be working. No codes set. Anyone have a suggestion where to start looking for the ABC comm issue? Thanks!
