Yesterday I updated my Nuvi 2595 to City Navigator Europe 2018.2 which is now split into 2 files, North Europe in D6210030A and South Europe in D6210040A. For earlier versions Garmin Express had stored the single big .img file on the SD card as there was insufficient space on the device itself.

After the update everything works fine BUT I can only find the one .img file on the device in \Garmin\Map and the SDcard is completely empty/unused.
\Garmin\map contains 5 files: D6210040A (South) .img .unl and .gma, but only D6210030A (North) .unl and .gma, the .img mapfile is nowhere to be found and I've searched everywhere on device and SD card.

I'm really confused as it is all working (I can zoom into North locations in full detail) but it is as if the update failed as the device is 99.9% full and the .img file is nowhere to be found.
Does anyone know where the data for the North map (D6210030A) could be stored? I just prefer to be in control and understand what's going on..
