Where Is the DCM in a 2024 Lexus GX550?

The DCM — the Data Communication Module, part of Safety Connect / Connected Services — is the module our bypass harness plugs into. Finding it is the only tricky part of the install. Pick your vehicle and we will show you where it lives and what has to come apart to reach it.

Not sure whether your vehicle even has one? Look for an SOS or Call Toyota button near the rear-view mirror or in the overhead console. No button means no DCM — and no need for the bypass harness.

Short answer

Directly behind the nav/audio screen in the centre dash.

We have not verified the disassembly for this vehicle yet - ask us before you plan the job.

Where it is

Directly behind the navigation / audio screen in the centre of the dash - the screen and its bracket come out to reach it.

How to get to it

We do not have a verified factory removal procedure for this vehicle yet. The location above is confirmed, but check a service manual for your exact model - or email us and we will help you plan the disassembly before you start.

No SOS button near the rear-view mirror or overhead console means the vehicle was built without Safety Connect - there is no DCM to bypass and this kit is not needed. Despite sharing a platform with the 2024+ Land Cruiser, the GX550 does NOT put the module in the same place - the Land Cruiser has it down in the console.

The bypass harness for this vehicle

Our bypass kit disconnects the DCM without losing your front right speaker or the hands-free Bluetooth microphone — the two things that stop working if you simply unplug the module.
