Since I have always been disturbed on the disc of the disc holder of navigation devices that "love bites", I immediately ordered the air vent mount with my new TomTom. Adjusting and attaching the bracket to the vents in my Peugeot 307 (Bj. 2003) presented no problems are. Infected too, and pull the TomTom works smoothly. Keep doing the holder also. An approximately 2 cm protruding ball joint would improve the view of the TomTom might if you could adjust the viewing angle so. Since the Navi evenly seated on the vent. In sum, I regret the purchase in any way and can recommend it with a clear conscience.
