BlueChart Card Caution and Unlock Disclaimer CAUTION: Do not use preprogrammed BlueChart cards for saving MapSource maps. The preprogrammed data will be lost. Remove any BlueChart cards in your Garmin unit before transferring MapSource maps to the unit to avoid losing the preprogrammed data. If you overwrite the preprogrammed data on a BlueChart card, Garmin will not replace or recover the lost data. DISCLAIMER: Your MapSource unlock code is valid for use with your own Garmin unit. You must have a separate unique unlock code for each Garmin unit. If you own more than one Garmin unit or upgrade to a new Garmin unit, you must have a separate code for each Garmin unit. If you personally own two Garmin units, you may obtain a second unlock code for the same region for your own personal use at no additional charge. Simply repeat the unlock process for the second unit. No more than two Garmin units may be unlocked with the purchase of a single unlock code. You must purchase a new unlock code if you have already unlocked two Garmin units. Information about obtaining additional unlock codes can be found at: my.garmin.com. This agreement provides a one-user license and it is illegal to share this data with others. Garmin does not give refunds or exchanges for MapSource unlock codes.  BlueChart User's Guide
