They suggested I call them, but I was able to come up with the answer
without that.

I've been unable to see towers displayed on the map pages as shown in

Full map or compass overlay in the Aviation map. You will not see the towers
in that mode until you get the range down to a certain amount, say 10 miles
or less or something like that. As you increase the range, the lower towers
disappear, leaving only the very tall towers, and finally no towers. Guess
their reasoning is that if you are using a large range you are high and no
problem with obstructions.

the manual. I am unable to see taxiways. I've not found a description of
this anywhere. I assume that is what the Taxiways file is and it is only

That's the file and if you look on the website, www.lowrance.com , you will
find they have a file you can download (it's the same one in your present
unit, I'm sure) and it contains the larger airports, part of a gov plan. At
this point that plan has 80 airports. There is a map of the US showing the
airports included in that gov plan. To test, choose a large airport and
decrease the range and you will see the entire taxiplan, with labels.

I tried copying the files from the OEM SD to a new 1 GB SD from CompUSA.
The files appear in the 'Browse Files' menu just as they do on the OEM
SD. However , none of the data is available.

I don't know about all of the files, but I _do_ know that the Jeppesen
database and any files you create with Map Create are assigned to the SD
serial/id number of that card. You can't copy the Jeppesen database to
another card and have it work. This is stated in the manual. The only thing
you can do is use the download facilities and download a new database for
$35. When you do, you must download a Jepp file/program which 'unlocks' the
encrypted file and assigns it to the SD card you have in the reader on your
computer, which you will then place in the GPS unit. All of this is
explained in detail on the website. There is an option to purchase a larger
card with the Jeppesen database on it, rather than download.
