Hi everyone,
Here is my dilemma. I purchased a Garmin GPS 421s for my husband with the Bluechart Vision G2 Hawaiian Island map. Apparently Garmin decided to down grade this card after March. So the older version shows the important details that my husband needs to navigate the seas. The new one is completely worthless. His friend has the older version and gave him a "copy" of the chart on an sd card. When I install the card it says can't unlock maps. How can I unlock this with my computer or his GPS 421s? If anyone can help me with this I would be so grateful...hell...I will send you a special care package from Hawaii! :D Mahalo(Thank you) in advance!
