The support allows to place a GPS with 11 cm screen and suction system "easyport" center right of the dashboard when it has a fairly flat beach. Longer need to hang escrimer GPS on the windshield or stretch their arms to make adjustments. Tried on a Citroën Berlingo, one of the bearings exceeds a little but support allows for GPS at hand and still maintaining a distance of at least 40 cm from the body of the driver (useful and recommended for some people). It is itself equipped with an adhesive system on the back, protected by a pad but I have not removed for use on other vehicles (and show it to someone who is looking for a on the dashboard rather "steep" a Mégane). The system is easy to place and can easily be stored in a drawer of the vehicle (including the Berlingo nasturtium). The suction cup GPS glues well on fairly wide central part. It remains to test the stability of the assembly on a long journey but it is one of the least expensive market research and after comparison supports. Be careful when using such a support check that GPS can be reversed automatically (which is the case of most recent GPS).
