The thieves can be stupid too....

I've known this happen the other way around....someone I knew had their TomTom stolen from their car. A few weeks later it was recovered, which was a miracle in itself as you'll see.

The police then phoned to say they had the unit and were surprised to find on it a log of where the thieves had been since they had used it themselves - they had caught one of them who had the unit in their own car. It led them to all sorts of places including their lock-up containing boxes of other stolen sat-navs and other swag. LOL.
