I usually crate the custom map with Mapsource and then upload it on a SD card. BUT the two parts have the same FID and, when I crate the second-part-custom-map, Mapsource overwrites the first one also on the SD.
I hope I explain myself better.
thank you

Firstly your nuvi 250 was not designed for NTU maps but NT maps
Yes, Mapsouce produces .img files only named gmapsupp.
Check in your garmindevice.xml to see if there is gmapsup1 show this tell us you can have 2 maps on the SD card named gmapsupp.img and gmapsup1

Is there a way to combine the two parts on Mapsource to have one gmapsupp only? Or to change the FID of one of them? It is weird that I can see only half Europe.

By the way, thank you GarminNuvi! Your help is precious.
