Can anyone tell me what the maximum map size a garmin nuvi 50 can read from an sd card. i have an old nuvi 360t and it cannot see the new large maps..

And is the map unlocked ?

not sure does this make a difference ?
sorry new to all this ....

Of course you need an unlocked map and place the map in a folder with the name Garmin on a SD card.
And the map must be renamed to gmapsupp.img
So time to read the Garmin section.
