Maps in navigation obsolete the day when it was purchased and it was no wonder that here and there where the menu does not know what change was made and paid would go to the new road instead of lettuce where you just fall off the exhaust. Maps can be updated through a program mostly supplied by the manufacturer, or downloading files to the card or directly into the GPS memory.
Map manufacturers update their data mostly as a quarter / half year. Someone, it seems that little time, but the truth is that many roads disappear or arise in the short term. And it is not just about the journey, but the POI points of interest, current information such as phone number, name of the item. These are all details that you need on your journey easier and your guidance and lead you to the destination without undue delay.
How to update your Garmin navigation? Very simple and mostly free! Download routovatelnou map of the Czech Republic in IMG format and play it for navigation. The procedure is as follows.
Unpack the file using the archiver. I recommend 7zip
The archive will find a file named gmapsupp.img that you upload to the Garmin folder on the disk, under which we are enrolled in the navigation computer, or on the card.
The directory structure on the SD card
If you want to save your work and the larger card is a handy backup old GMAPSUPP to be generated MapSource. If you overwrite the original file, so you lose your maps and you'll have to reload via MapSource.
Pretty simple eh? Best of the matter is that "update" to do each week and therefore you have always the latest map data! And if something is wrong, the speed of communication not match the actual situation in reality, there is nothing easier than to register OpenStreetMap and correct the error and help others
And finally, how the map looks like?
