    Default Removal of certain map files on internal storage in .System Folder

    Hi guys quick question. So i have the Garmin Nuvi 58LMT and i`m trying to free up space on the internal storage because its 99% full. I want to install my maps on my 16gb micro sd card instead. I have access to the .System folder and i was checking in on you guys if you know which files i should remove without bricking the unit. Thanks in advance fellas.

    Looks like you already have the latest USA & Canada maps installed.
    Garmin Express will normally ask you to use a SD card when the device capacity cannot cope with the update and split files between the device & SD card.
    What are you hoping to achieve by removing files from the device ?
    If it is space for something else then the obvious is move the gmapprom.img & gmapprom.unl to a folder called Map on the SD card change their names to gmapsupp.img & gmapsupp.unl
