There's some really active community discussions around disabling the Data Collection Module, discussing everything from simply pulling the DCM fuse to disabling only the antenna.

If you pull the DCM fuse, you'll loose the microphone and potentially one of the right-hand speakers - these can be fixed by jumping the wires in/out of the DCM.

What's concerning to me are reports of the car still uploading all the collected data if you attach a cell phone to the radio's bluetooth. Apparently the car just relays all the info.

I kinda want to snoop that data and see what it is, at least collect the encrypted packets... but my car is from 2007 and has no connected features, so...
