I drive a Touran and have glued the plate for my TomTom XL on the hinged lid of the tray on the dashboard. At first I was skeptical (outdoor temperature -5 degrees), but when I stuck it, I can no longer even dislocate one millimeter immediately afterwards. She holds bombproof since. Even the regular removal of the TomTom has the adhesive properties can not diminish. She has since survived the freezing temperatures without damage. I would recommend the article without restrictions.
And a further advantage is the second "spare disk" if one of the selected place for TomTom but not suit you in daily use.
To the possible dust on the disc that is not holding the bracket enough, I can only say that I always leave the bracket on the plate and the TomTom decrease so. But is also the TomTom and the holder. Mine is already the newer version (EasyPort)
Greeting
Update:
The plates are now more than two years in our cars (garage and parking space). It has still not changed. Furthermore, I am very satisfied. Even holders of other manufacturers hold Bombenfest.
