What bike computer w/ GPS, has true tracking capability?

The Best Bike GPS of 2016 | Top Ten Reviews

The reason I am asking. Is because, the Android phone I have, is a pain in the (you know). Because, It is not good for someone with eye-hand coordination, and fine-motor skill, problems. So, I am going back to using a flip phone. While that will take care of my disgust about the Android phone. That doesn't solve the tracking problem.

Any feedback as a bike computer that would make it possible for Police/EMS to track and find a cyclist.

I have both, the Garmin Edge 200, and the Garmin Edge 500. The 500 tells me where I have been. But it can't be tracked. At the included website, it doesn't say if any of the bike computers have GPS tracking.
