Clarification on DC Charging Speeds: 2024 Twin Motor

Hi all, I'm getting a lot of conflicting info on what the actual peak DC charging speed is on the 2024.

Volvo's own spec sheet for the US is saying 200 kW. I'm finding other sources saying it's only 150 kW, and only the European model got the 200 kW.

Can anyone in the US with a 2024 twin confirm what charging speed they're getting?

Been researching the infotainment upgrade problem that every pre-2024 LC500 owner knows about. I think I've found the cleanest possible solution and wanted to share the connector analysis before I pull the trigger.

The idea: Swap the OEM 2024 LC500 touchscreen head unit directly into a 2018. Native CarPlay, native touchscreen, OEM fit and finish, Mark Levinson preserved.

After getting high-res photos of both units and comparing carefully, here's what I found:

Both units have the same 4 connectors:

  1. Large multi-pin data/CAN connector (blue housing on 2018, black on 2024 — same pin count and layout)

  2. Blue optical connector — present on both, same form factor (this is the critical one for Mark Levinson)

  3. Secondary data connector — present on both

  4. RTI/sub-module connector, this one had me confused at first. I initially thought the 2024 eliminated it since touchscreen replaces the trackpad. But looking more carefully, it's still there on the 2024, just repositioned to the far left of the board vs the right on the 2018. I assumed it was for the RTI but maybe not.

Both units are DENSO TEN manufactured. Part numbers: 2018 = 86110-11040, 2024 = 86110-11190.

**What this means:**

Lexus appears to have maintained the same electrical interface across the entire LC500 production run. The connector change from blue to black housing on the main data connector is cosmetic — same pins, same layout.

**Remaining unknowns:**

  1. VIN programming: does 2024 unit need to be married to the car's VIN? Can a dealer or independent shop do this?

  2. Physical fitment: There would obviously need to be some jerry-rigging, but Lexus seemed to just slap the tablet on the old dash and covered the back with soft-touch.

  3. CAN bus protocol: did anything change between 2018-2024 at the software level that would cause issues?

The 2024 unit is on eBay for ~$1,650. Expensive but it's OEM, preserves everything, and looks factory because it is.

Has anyone attempted this or have info on the VIN programming question? I have a software engineering background and am comfortable going deeper on CAN analysis if needed. Happy to document everything if I end up doing this swap.
