Addendum on 14/06/2012:
I need to review korrigieren.Ich suspect that it is the area itself. In my Clio for example, there is no coherent flat surface. In other words, the pad can nowhere evenly rest with the three "legs". The Clio simply does not support surface.
And because the pad can now really nothing for. Therefore, I give the pad now 4 star (I have tried it in company cars (MB) because it kept wonderful !!)
