I have similar experience. Just to add that if you want to load the
detailed street maps from MapCreate 6, you can only load a very
small map, covering 200X200 nm or so. This number is not
accurate, but an estimate. You have to spend $150 to buy
the "freedom" (or whatever the name is) SD cards.

I also have the 600C and think it is one of the best designed units on the
market with reference to features, software, and user interface. One method
of increasing the area covered in the terrain maps is to use what they call
corrider map borders and linking them together. I find the software somewhat
awkward with this, but it does allow you to have a large area, such as along
a road, covered without too much memory if you make the corrider rather
narrow.

The card reader that comes with the GPS has encryption function
in it, and is allowed to work on total of 5 SD cards. But you can
not duplicate the Jeppesen or Terrain database onto the after market

It is somewhat frustrating, but I rather think that they were following
Jeppesen's mandates and simply also used that same 'SD card id scheme' with
their Map Create.

But one nice feature is that you can simply buy your own SD card of whatever
size then download the new Jeppesen database for $35. If you read about all
of this, you find you have to also download, initially, a program from
Jeppesen (on Lowrance website) to unlock or 'key' the file with the SD card
id. I like the idea of being able to update the Jeppesen database without
having to mail in the old one and also not subscribe.
