I must wait till weekend to get my new Navigation. It´s a MK4, course the lastone (MK3) won´t work and coult need a new Laserunit, or software ...

@ccfj1:
Thanks alot for your help and so I´m understanding what happing by "Select-Language" to switch the POIson/off.

When my German-Version already done, i´ll still upload it, too.

But I´ll change ALL languagefiles to german. So isn´t necessary to know, how does the navi coded. It´s enough, when 1st ist GER and the other is xyz and it will works fine...
