Does someone have the file list for Garmin Nuvi50 with North America NT 2013.40 map on SD card ?

I want to know what file that Nuvi 50 should use with North America 2013.40 Map , like what JCV file should use and does it support 3D building map file ?
Does SID or ther file needed ?

I check the post on North America 2013.40 , no include those information.

I get the map works , but no JCV worked . The post say should use the D3478070A.JCV (113MB) ,doesn't show any more information on unit. I get the last version North America 2013.30 JCV file D3478060A.JCV , but still not see the Jcv function .

Could someone help me on how to load the right file on it and how to verify it in right way?

Thanks.
