Another OPTI-1 Success story, and big thanks to jbondox
illumination & ignition at cig lighter
reverse at light or rear sam
when removing the comand, set the instrument cluster to display audio and set the comand to radio am or fm before disconnecting the power
CAN wires can be also taken off the A/C controller but since you are going to the gateway it is up to you.
Rear camera is a treat to run in that vehicle! bust out the bourbon for that!
BUT, I'm fearing that I may have buttoned things up too soon. QUESTION: Can I tie in the reverse signal somewhere up front? Or do I need to route my cable to the reverse lamp in back?
Thanks for any additional guidance you can provide!
1. Reading the NAVTV Opti1 instructions it refers to connecting the antenna of the new unit to the audio gateway AGW. It states this is located behind the drivers seat in the side panel. Is this what you experienced? Odd that it wouldnt connect up where the Comand is located. Also states you need to pull power from the fusebox behind the passenger seat. Cant you access power from where the Comand was powered?
2. Looking at wiring harnesses it seems I need a CAN Bus adapter am looking at Axxess BXMB1. Is this correct? Are there any other wiring adapters to avoid cutting into the factory harness? I know I need a Metra ASWC1 for steering wheel control. Just want to be sure Im not missing anything.
3. Aside from setting AM radio to mid volume, balance and tone before removing the Comand are there any other preparations? The manual mentions decoding voice recognition??? I dont have a factory phone or anything. Just ignore that??
4. I am going to remove the dvd changer after install. Can I just leave the MOST bus cable loose or does it need to be terminated someway?
5. Here is my parts list. Am I missing anything? Any extras I ought to be thinking about?
Pioneer 4100NEX
NavTV MOST HUR MB-S Opti1
Metra ASWC1 Steering Wheel control
Axxess BXMB1 CAN bus adapter
Metra 40 EU10 antenna adapter
NAVTV SL Dash Plate
Thanks much for any assistance.

Hey Bob, did you manage to get this installed in your SL55? I just went through the same process with my E63, so have some knowledge while it's still in my head.
Radio antenna to the AGW is not entirely true. You actually disconnect the antenna connector from the AGW and connect the cable to it. If yours is the same, there's a 'pink' piece on the connector that you lift up with a small screw driver, then you can press down end to lift up the connecting latch. It took me a while. I didn't realize that and almost yanked the cable out. I'm not sure if you can pull the power from the original connector. I just pull it from the fuse. Either car seat controls will work. They 12v connector to 30 amp fuses.
I ended up tapping into the canbus wires, so don't know about the canbus adapter you are referring to.
Yup, just ignore that. My car came with "voice" command system but it wasn't working already, so I ignored it.
Don't remove the DVD changer as this is part of the MOST system and is needed in order for all the devices to work. I think in order to remove it you'll have to use STAR diagnostics unit to remove it from the MOST network.
So if I go this route Ill plan on making an appointment with the dealer first to take the dvd/mobridge out of the loop. And I suppose the nav unit too.

Any tips before I dig into my install? Anything you would have done differently?
Thank you
Also, I didn't know about putting the factory H/U in AM/FM before removal. I assume, but probably shouldn't, that is just for the benefit of using the factory antennae. Do I need t o worry about that if I am using a different antennae ?
