But is it illegal to personally disable it?

No but it often involves voiding warranty and/or labor-intensive, really annoying work to access something you can disable.

On Toyotas, you simply remove a fuse [which can be re-installed].

Random question, but will this be open sourced at any point? Just asking as a curious party who just bought one for exploration lol Also super random question but would you happen to have any idea/advice on how to get a Raytac MDBT50Q-CX Nordic nRF52840 Dongle ( https://www.amazon.com/gp/product/B0DP6MVDZQ ) flashed with ButteRFly ( https://github.com/whad-team/butterfly )? I got it flashed through nrfutil with sniff…

Hi, sorry I missed your reply - Unfortunately it's a proprietary design, the vendor provides the firmware, I do all the schematic capture / PCB layout. Good luck though!

Thanks!! Had to at least ask lol

I can assure you this is not the case with all Toyota models or even most. It's often integrated into the radio instead of a separate module, or simply not on a dedicated fuse, but sometimes it is. Disabling it can also lose other features of the car such as navigation, remote start, the Bluetooth mic, or the mandatory eCall feature if you're in the EU.

On all 2016+ US Toyotas, removing the fuse labeled "DCM" will disable the following:

•) Wireless communications module (including OnStar and telemetrics)

•) Front passenger dashboard speaker (there is an easy bypass to re-enable, but must open dashboard — in which case just remove the entire module!)
