Sure, just transmit stronger white noise on 433.92 MHz. I haven't looked up who owns that frequency and whether there are restrictions. Or get a GPS blocker. W

Or get a GPS blocker. Which I think are illegal to operate.
- a1k0n 15y agoAFAIK 433MHz can be used for any short-range application, similar to 27/49MHz for R/C cars. There are plenty off-the-shelf 433MHz transceivers for hobbyists, and I think car remote-unlockers use that band as well. And this doesn't appear to have a particularly powerful transmitter, so you'd have to bring the transmitter relatively close to the receiver (like <100ft, usually) in order to download...whatever. If they're able to put this thing on your car in the first place, I guess it's not infeasible for them to drive by to download updates.
