    Is your Mapsource or Basecamp slow in rendering maps or OSM maps are fuzzy? solution



    Recent MapSource versions use a cache to speed up map rendering. The drawback is that until the cache is refreshed, you will continue to see what is in the cache rather than what is actually in the data. One answer is to pan around, zoom in and out, for a bit until the cache is updated.

    And now, when we zoom into a map produced with mkgmap, like the OSM maps,sometimes the display gets corrupted. Roads and rail lines become fuzzy and get multiplied horizontally

    Control-G hit twice will flush the cache and clean up the image with newer versions. The first Control-G may blank the screen. The second will bring back a cleaned up image. But it wont delete all the files in the tiles cache.
    Rendering problem is the same in BaseCamp.

    The better solution is to wipe the tile cache, as follows.
    Note: The Application Data directory is a hidden system directory

    For Windows Vista users, empty the following folder of all files:
    c:\users\YOURUSERNAME\appdata\roaming\garmin\mapsource\tilecache\
    where YOURUSERNAME is...your user name.
    In Xp
    c:\documents and settings\YOURUSERNAME\GARMIN\mapsource\tilecache

    Even better, create a batch file that automates this for you by running the following command (for Vista):

    del /Q "c:\users\YOURUSERNAME\appdata\roaming\garmin\mapsource\tilecache\*.tile"

    (for Xp)

    del /Q "C:\Documents and Settings\YOURUSERNAME\Application Data\GARMIN\MapSource\TileCache\*.tile"

    This can be done for Basecamp too.
