I have an old nuvi 205 (without the "W"), that has only gmaptz and gmapbmap installed in the internal memory.
So I wanted to update the device with the latest map - so with the Europe NT 2025.10 (the latest NT maps for Europe).
The thing is, that I've accidentally copied the file "South (D6210320A).rar - 2.4 GB" from Europe 2026.20 NTU onto the sdcard.
There is 100% no other maps on my device, because if I eject the sdcard, it says "there is no detailed maps ..."!
But now I can enter the address and the nuvi makes me a normal route ... :o
So whats the catch? I thought NTU map shouldnt work at all if a garmin only supports NT maps :o
Or will I notice some other problems during usage?
