I bought this Arkon suction cup mount back in early April of last year, to use in my US-spec Abarth. Despite being a suction cup mount, it actually works great. I have it mounted on the front of the dashboard (hard plastic area; it looks like the 595 has the same type of material here?). In the nearly 17 months that I've been using the mount, it has fallen off twice. So I would venture to guess that if I were simply to pull it off every six or so months, give the suction cup a quick rinse and reinstall it, it would never fall off. Which is really not bad.
Here's a link to the product on US Amazon store, but I'm not sure if it will help much since you must not be in the US yourself (if you're getting a 595).

Also, here is a link to some pics of the one I bought, installed on the dash in my Abarth. These are pics I took shortly after getting the mount. The phone shown in the pics is an iPhone 6S Plus; the mount will also accommodate smaller or larger phones, though. I showed the mount to two friends after using it for a little while, and they both went on Amazon to order one for themselves (and have been equally happy with theirs, last I heard).
