I have the same exact setup. It is a pain in the ass to figure out. Do you have a MAC or PC? you need to install Garmin Map manager. Then unlock the map that you downloaded. Then you need to download Mapinstall and open it and plug your Rhino into your computer and it will show up as a device. Then you can choose the map to be installed. This is what i had to do. But i have a MAC so it might be a little different.
I have some ideas. Will post later.
