Found the MOST fiber and power connections, have that all squared away, but unit won’t power on as it seems a CAN-H and CAN-L connection is required for that.
Their customer support is helpful…sort of…but is also 13 hours ahead and responses take a while.
Have looked all over for days trying to answer, worth noting 2005-20011 have similar interface and it is shared with other Mercedes models…but CAN BUS location for wire taps near HVAC controls or foot well is eluding me.

Tapped Cigarette Lighter for accessory power…everything turns on but still no luck with what/where to tap CAN-H and CAN-L
Believe CAN tap is needed for comms like reverse sensing to activate camera, steering wheel controls, and I’m sure various other things.
Anyone know where CAN location is around HVAC controls hopefully? I have seen it could also be above driver footwell or left drivers side door but don’t want to rip car apart if there is easy location I can tap around center console for CAN.
Thank you but CAN and fiber are different on the car in this video - the install on pre 2005 are much more intensive than post 2005 as everything is supposed to be able to be done up front in/near center console only
Can't help with your question, but I have a general question about installing this new Android head unit. This particular head unit seems to be the only available because it's the only one that comes with a bezel to match the space in the Mercedes dashboard. Is that also your understanding?
In searching for such units, I've seen units that look just like your Seicane offered on eBay and Walmart, for as little as $95.Do you know if these are all the same device?
When you ordered form Seicane, did you order any of the "required" items? Any of the optional ones?
There are only two different fitments in R230.
First one is as seen here, where the headunit fits inside the console, with trim all the way around it. This normally is on the D2B systems.
The other is where the head unit fills the entire space above the cup holders and the console trim does not surround the head unit.
The cut off is about 2005 and when MOST was used.
There are two or three different head units for each variant of the original headunit.
I just fitted one to my 2025 BOSE car, and quite impressed for the price I paid. Mine Keeps the cup holders as a bonus.
