    hello, can you please give me a hint ? i can copy unlocked IMG files of Topo maps onto SD cards up to 8GB directly from WIN7 PC to SD and my Oregon450t will show them; if i do the same on 16GB cards my device will not show them; same effect if i do the copying via MapInstaller/Basecamp ? any clue what might be the reason ? thxs in advance .-)

    From :

    * There is no limitation to the size of SD/microSD card used but the device will only recognize 4GB (in some old devices 2gb) 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.

    BUT...WHAT ARE THE LIMITS, REALLY??

    Mapset Segment Count:
    As far as I know the mapset limit should be still 2025 map segments on most Garmin devices, regardless of filesize. (MapSource might not care but your device might choke anyway if there are too many segments.)

    But, Oregon and Colorado and 62s can handle mapsets with at least 4000map segments. There appears to be some evidence in the Garmin Colorado and Oregon Wiki from actual use that supports the 4000 number.
    Basemap+preloaded map+user added map=max 4XXX (4096? 4k ?)
    The 60CSx supports a maximum of 2025 map segments by comparison.

    All MicroSD cards at 16GB, or any other capacity, are not the same. If you check the card you'll find another small number inside a "c" (class) letter that indicates data write speed of the card.

    MSD3 MSD2 MSD1

    As you can see we have three different speeds for the same capacity 2, 4 & 10 MB/S and sometimes this spec could be a problem for some devices as they are not compatible. I'm not sure that this is your problem, is just a thought and something you may want to try with different class MicroSD cards if you can.
