I found this in my car-any idea what it does?

It is a little bit larger than the two tracker fob that I already have for my Navtrack system. Any idea what it does? 2006 612

It's a Navtrak ADR tag

Thank you. Can you tell me how it is different from the two other tracker fobs that I have in my car? I attach an image of one of them.

Would have been one of the ones originally supplied with the car but does the same job as the later one you have there that were introduced when it became Cobra Navtrak. There's a new one again now with Vodafone seemingly taking over

I was informed the original Ferrari ADR cards were unreliable (didn't work) so the Cobra standard cards were provided as a fix???
