Pro.Fit's VSM G3 vehicle-specific mounts feature an integrated mounting ball for the Garmin nüvi. If a VSM G3 isn't available for your specific vehicle, this package offers an ideal solution. The package includes the nüvi adapter plate and Pro.Fit's "A Plate" adapter — the two form a tight, secure connection to hold the nüvi in place. This combo secures your Garmin nüvi portable navigator to one of Pro.Fit's universal or vehicle-specific mounts, allowing you to place your nüvi on your dash or console.

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 vehicle-specific mounts. Warranty: 1 year.

Good Accesory Mount

Written By Sailwin, Rio Rancho, NM on Saturday, February 22, 2014

Crutchfield Customer Review (What's this?)

Straight forward mount. Made of Plastic, maybe ABS, Ball lets you mount a Garmin or Garmin Style holder to it. Highly Recommend if you need, but most mounts come with this.

Pros: lets you mount a Garmin or Garmin Style holder to it.

Cons: Highly Recommend if you need, but most mounts come with this.

Awesome product!

A really nice adaptor to use with the iphone. Makes the LoBoy mount adaptable to the Garmin-style iphone mount.

Pros: A+ No problems that I am aware.

Product Research


Overview: The Pro-Fit TT-39 is specifically designed to fit the Garmin nüvi series portable GPS units. The holder makes in-vehicle operation of your nüvi simple and easy. The TT-39 has the same sized mounting ball as the nüvi's suction cup mounts.

Installation Requirements: The TT-39 comes with the MG-032 Two Prong Adapter which attaches to any Pro.Fit vehicle-specific or universal mounting solution. Once mounted, the TT-39 Garmin nüvi adapter easily attaches to the Two-Prong adapter.

Note: The TT-39 is not a stand alone holder. Another Pro.Fit VSM or universal mount is required. It is not necessary to use the TT-39 with a Pro.Fit G3-series VSM because the G3 mounts have the same Garmin nüvi mounting ball.
