You can use the JCV FULL SCREEN (D3084210A.jcv) ...

The full-screen D3084210A.jcv can be converted to a split-screen JCV.
Try my modified D3084210B.jcv above if you wish ...

Is it available to convert split-screen JCV (NTU) to full for old device (NT)?

This is not a conversion in the full sense of the word. I just resize the picture in the JCV header, then the device compresses or stretches the picture respectively.
You can stretch the split-screen JCV up to a full-screen image, but use it with its native map only.

So I can add my customs resolution to any JCV?!
I am going to offset 6C -> add my damned resolution for X and Y -> correct offsets for surplus 8 bytes in header -> and I will see what do not see anybody before?

It's not all that simple. Let's discuss this in the right place ...

Excuse me, but what is the sense of resizing the image of JCVs?
The device already does it. Another thing would be to replace images with others of higher resolution.
For me it is a completely useless operation, or I did not understand what you mean

Hello all. But first, many thanks for your help because I am trying some maps for my Zumo 310 (free maps freizeitkarte and OSM) for fun and testing during winter. BUT, FireFox58, when I want downloading France + Corsica from mega.nz, my firefox mozilla refuses to do that and no way for bypass "La connexion n’est pas sécurisée
Les propriétaires de mega.nz ont mal configuré leur site web. Pour éviter que vos données ne soient dérobées, Firefox ne s’est pas connecté à ce site web.
Ce site a recours à HTTP Strict Transport Security (HSTS) pour indiquer à Firefox de n’établir qu’une connexion sécurisée. Ainsi il n’est pas possible d’ajouter d’exception pour ce certificat."
So, somebody can upload France+Corsica on zyppyshare or something like that ?
Grands merci if you can and big kisses if no, it's just a game for me playing with my Zumo !

EDIT: as usual, I beg your pardon for my approximative english.

The point is that user bondi699 asked for a split-screen JCV, but such a file is not issued for this NT map. So I suggested that he try a pseudo split-screen JCV, obtained from a full-screen JCV.
See my post #44 above ...

Unfortunately, this feature is only available in Asian firmwares:

Good morning from Greece.I have the Nuvi 855 and i try to put the new map of Europe but it does not see it.Either the Balcan map.

Is there a new map either for Greece or Europe (2018) that can play at old devices like mine?

Thanks a lot

I manage to put and work Autodrive 4.50 and Anavasi 6.45...The new Autodrive 5.00 wont see it either the new Europe map 2018

Unfortunately your device should support map files up to 2GB so you have to download and install the Mapsource for PC and from there with the assistance of the Mapinstall to choose and install all the possible areas you may need
The Anavasi is a very poor map

I manage the gamrin to read the balcan map...I remove all the maps and i copy only the Balcan at SUPP name...Thats it....All ok....Then i copy the Anavasi because the Balcan map has not all the off road paths..Thanks a lot..I will download the Mapsource and MapInstall...Thanks a lot!!

For Mapsource wich links sould i download?Thanks
