Locus pro on Android device without Google Play
I have a Garmin overlander GPS that runs Android but it does not have the Google play app. The maps that are available for the Garmin Explorer app is not good enough, so I am trying to find a way to get maps of better quality. Can you download and use Garmin .img-maps with the Locus app without having Google Play? If not, is it possible to have the pro version without Google play on the device? Or is Google Play the only way to verify that you have paid for the pro version? The GPS has a browser and internet connection via WiFi, but I would like to hav maps on the device going of grid.
The Garmin overlander supports sideloading apk-files to install Android apps.
