Before you purchase ...

Ensure that your GARMIN device is one of the following models:

  • Nüvi® 

  • Dakota® 

  • Oregon® 

  • eTrex Vista® 

  • eTrex Legend® 

A single mNav Map license retails online for 140USD 


Note 1: mNav maps will in NO way interfere with your existing maps of the US, UK, Canada, Europe, etc. on your Garmin.


Note 2: Purchasing an mNav map entitles you to one FREE map update to the next version. Subsequent map updates cost 40USD (online) per year for unlimited updates within the year.


KENWOOD DNX OWNERS: If your map is to be purchased for a Kenwood DNX series in-dash system, you will NOT be able to perform it online. This type of install can only be performed at our office. Call us at 1-868-662-3605. 


(Disclaimer: mNAV maps are installed as a supplementary image file in your Garmin. Any existing supplementary image files will be deleted. Maps of US, UK, Canada, Europe, etc are NOT installed as supplementary image files and will therefore be protected.)
