You are wrong, in the ad absurdum extrapolation in this thread that using a phone for navigation is illegal in “all of Europe”.

You presumably meant EU, a part but not all of Europe, but that too is wrong. For example, the law in the Czech Republic, a member state of EU, states that it forbidden to hold a phone (or other handheld device), in hand or otherwise (e.g. between shoulder and ear) while driving (§ 125c / 1f) 1. z. č. 361/2000 Sb.).

Handheld devices probably are illegal to use while driving in all of EU while being (hand)held, but absolutely not when mounted and used in the same manner as car’s builtin display. It may be the case in some country, but is not true generally.
