Almost all of them do turn on though but I have no idea if they work. 6 Garmin chargers are included

This lot includes 18 mixed GPS navigation devices by Garmin and TomTom, as well as 6 Garmin chargers. The GPS units are automotive mountable and come in a variety of models from both Garmin and TomTom. Unfortunately, these units are untested, so their functionality is uncertain. This lot may be ideal for individuals looking to try out different GPS systems or for those who enjoy tinkering with electronics.
