OK...I wanted to update this post for future readers. First, the software needed is Bluechart Americas by Mapsource (Garmin). The GARMIN Trip & Waypoint manager does not work for marine applications (No marine charts) - so this was a needless purchase on my part.

Also, they have a newer software versionof Bluechart Americas - "Bluechart 2008", but it has not shipped out to dealers yet (Not at WestMarine). Garmin was nice enough to say that should I buy the older version Bluechart Americas Version 9.5 now and provide proof, they would provideme the 2008 Unlock codes when its available, for FREE and they sent me an email confirming this! Second, although not mentioned in the box I received, YOU HAVE TO INSTALL THE DRIVERS FIRST BEFOREATTACHING THE USB CARD READER. You also need to be careful that your USB port at your computer is a 2.0 (Fast) speed ready or there may be a problem withdownloading the updates to the card.Also, there is a potential problem for those that connect the USB 2.0 Card Reader to a USB Hub (Multi USB's). You may need to connect directly to the back of your computer, instead.My USB port at my computer is an older version, so Ihave that problem now anduntil I geta newer USB port in my PC that reads at the newer 2.0 speeds, I have to manually download to my cards (Online). Thirdly, you have to buy a blank User card with at least 32MB of memory, or your downloads won't fit. Most ofwhat I'm saying here is not contained in any literature or its sporadicallyplaced. Also, the Bluechart Americas software will require an "unlocking" code that comes in the software package, but this will require that you have with you at time of installation your GPS Unit serial number, becauseeach "unlock" code is specific to only one GPS unit. Garmin will give you a second "unlocking" code for free, if you have a second unit. I have a second and will require another "unlocking" code.
Hopefully, this will help some members - this infois for those readers similar to my situation - i.e. GPS 3210 & 3005 and with a 2.0 USB Card Readerwishing to download version updates and create waypoints and routes on your PC.GARMIN was very helpful and a special thanks to BWP.
