to all interested parties: with the help and guidance of the forum the NTU map works on zumo340; what had to be done: remove the built-in CE map (gmapprom.img and associated files), load the NTU map (gmapsupp.img) on SD and related files into zumo .sys folder; i even managed (catymag's thread for sound files on POIs) to customize speed cam alarm tones; great ! only one thing does not work - junction views - and i wonder why ?! i copied the JVC file D3048160A.JCV into the JCV sub-folder of the .sys Folder, but the zumo340 will not Show one single junction view; Routing works fine, voice routing instructions work fine, just no junction views ...; any hint on what to do to set this straight ? thxs in advance, matthias
