This Pro.Fit adapter plate combo secures your TomTom ONE XL portable navigator to one of Pro.Fit's universal or vehicle-specific mounts, allowing you to place your ONE XL on your dash or console. The package includes the ONE XL adapter plate and Pro.Fit's "A Plate" adapter — the two form a tight, secure connection to hold the ONE XL in place.

You'll need a mount to complete the installation in your vehicle — the "A Plate" fits with most Pro.Fit universal mounts, as well as the VSM and VSM G3 vehicle-specific mounts. Warranty: 1 year.
