Functionality of Devices & Apps

Not every Device or App we support can accommodate each of the four Versions of the data we provide (Version info). The chart below indicates which Versions can be installed to which Device or App. Likewise, not all the Devices or Apps allow the installation of custom display icons. If they don't, then a default icon is used (this doesn't affect the functionality of the data). We provide custom icons for the Devices or Apps that will allow it. This is also indicated on the chart below.

 

Note: The facility to sound a proximity audio warning when close to a low clearance will depend on your GPS Device or App.
It may sound automatically, or require activation. Some GPS Devices and Apps do not have audio warning capability.
If you're unsure; please refer to your GPS Device or App's manual, or the manufacturers customer support.
