Sorry for the delayed response but here is some additional information I was able to gather for the Medallion Viper system featured in the MY2012 boats.
1. The Medallion Chart Plotter Application supports the following map Navionics Map Databases:
- For Boaters who boat primarily on Lakes we recommend Hot Maps Lakes Premium Charts.
- For Boaters who Boat primarily on Intercoastal waters we recommend Marine Gold Charts.
2. The card may only be inserted one way as there are tabs in the card reader and slots in the SD Card designed to ensure that the card is inserted correctly. If the display is oriented as shown below the SD card is inserted with the contacts facing up and the label facing down. When inserting a card you will hear a click as it locks into place.
The SD Card Reader is spring loaded. So to release the inserted SD card just push it in until you hear a click and then let go of the card and the card will release and pop out far enough that you can grab it. Go to the full post
