    There are limitations to the size of SD/microSD card used and to the number of detailed mapping segments that can be recognized by a device.

    If at the most recent unit software version, these limitations are:

    * There is no limitation to the size of SD/microSD card used but the device will only recognize 4GB of detailed mapping
    * Each expandable memory device will be able to recognize up to 2,025 detailed mapping segments

    If 2,025 detailed mapping segments are loaded to an SD/microSD card but does not reach 4GB worth of data, the unit will not show any more detailed mapping than what is provided by the mapping segments.
