U.S. Maps fit on a 1GB card

| Just purchased a C320 and have an extra 1GB SD card. Will all of the U.S.
fit on the 1GB card as we program the unit?

There was a thread on that a while back. I believe that the
end result was that all of the US required approximately
1.7G or thereabouts. It was only a month or so ago so it
shouldn't be difficult to locate.

If the C320 can accept NT compression, then City Navigator North America NT
will fit on a 1GB card. Unless someone with C320 experience can confirm that
it will, you can check the Garmin web site for compatibility with this map
set.

1.7 GB is needed for City Navigator North America whereas City Navigator
North America NT fits in 970mb. NT means New Technology and the only
difference in the two is that NT uses an improved compression algorithm.
They both have the same mapping details and POI.

Ah, ok thanks for the explanation Jack. I should have just
waited for your post in the first place. ;-D

| After checking the Garmin page....it says this unit does take NT so it
should fit the 1GB...Thanks.

Tomorrow, I'm going to look at a 60 CSx, meaning I'll probabkly buy it. I
have a 512 MicroSD that will from my Vista Cx that will be adopted by the
new GPS, so no problem there. Just wondering, the price has come down so
muich, will a 2 GB card work in the 60 CSx? I seem to recall a thread a
while back about the max size MicroSD that the unit will recognize, and I
think the answer involved testing by Garmin. Since the 2 GB is not longer
that new, I'm hoping someone will have an answer on this.

First, I congratulate you on your choice the CXx models are
great. Second, I'd suggest you compare the 60 to the 76 to
see which one you prefer. The 60 gets the most "press" for
some reason, which I don't understand, but I suggest you
look at both.
I don't know if a 4G card will work first hand. I have
"heard" that they will if they're Sandisk and not the
highspeed cards. Personally, I have a 2G Sandisk in my 76CSx
and it works fine. Piece of cake to get out if I choose to
as well, I don't have to remove the battery cover and
battery to get to it.
There have been reports that other manufactures memory cards
have issues so I'd recommend only going with Sandisk even if
it costs you a couple of bucks more.

Small correction, you do have to remove the battery cover, right? But
not the batteries as with the 60 series.
And I have three SanDisk 2GB microSD cards (standard speed) and they all
work well. In fact I've also used those card in the SD adapter in other
PDAs and they work fine, and if I put the microSD card in the SD adapter
and then put the SD adapter in a CF adapter, it will work in my 2610 too.

On the 60csx the memory card is seated behind the batteries, so yes, you do
have to remove the batteries to get at the memory card.

Someone who owns a highspeed card ought to test that with the newest
software update. It did say something about support for version 2
Micro-SD cards. This could possibly be high speed cards?

Except that you might find there's not 970MB of useable room on a 1GB card.
Check that out first- most storage devices have some overhead for whatever
reason. Besides that there's actually, if I recall, 1024kb to a MB. My
"160GB" hard drive, for example, only has 144GB capacity.

And as usual Jack, you're correct. Fat fingers
donchaknow... ;-)

Jack was questioning my statement that I didn't have to
remove the battery cover and batteries on my 76CSx. He of
course was correct. I do have to remove the cover, but not
the batteries. In the 60CSx, you have to remove the
batteries to get to the card.

Just wanted to correct a small inaccuracy. As far as fat fingers, I
have that problem with the microSD cards.
When I unseat a card I sometimes have some trouble getting a hold of it
and pulling it out.
Shortly after I got my 76Cx I was standing in back of a boat when that
problem occurred. I decided I would try pushing the card part way back
in, letting my finger slip off, and seeing if the eject spring pop would
pop it all the way out. And pop it out it did. Much better than I
expected it to. The microSD card went about three feet through the air,
skipped across the transom, and when last seen it was settling slowly
towards the bottom of the Kennebunk River.
That card was my first and brand new microSD, about $80 worth at the
time, and I clearly remember that it was sinking slowly enough that I
had time to think about jumping in and trying to catch up with it. But
it was spring, the water was cold, and I did not think the chances of
seeing it once I was underwater were very good.
So that was one boat delivery that I did not make much money on. :> )

It sounds like it was the Ultra-Speed card <bg> Thanks for sharing some
good memory of life <bg>

Hard drive specifications have usually been given with decimal prefixes,
whereas most other computer related equipment is given with binary
prefixes.
The 160GB hard drive = 160,000,000,000 bytes using giga = 1,000,000,000.
"giga" as a power of 2 exponent 30 = 1,073,741,824.
So 160,000,000,000 / 1,073,741,824 = 149GB.
The difference 149GB - 144GB = 5GB is the format overhead.
Decimal: kilo == 10**3 = 1,000; mega == 10**6 = 1,000,000; giga == 10**9
Binary: "kilo" == 2**10 = 1024; "mega" == 2**20 = 1,048,576; "mega" == 2**30

As for the 60CSx vs 76CSx, I guess it's a matter of styling. They are both
excellent. I just prefer the 60CSx. With a large capacity MicroSD card, the
process of swapping them out almost becomes moot. With 2 GB of maps, I
really can't imagine changing out memory cards too often. Right now, I have
a 512 MB card and I've loaded CityNav for most of the states contiguious to
where I live plus quite a bit of the Eastern Seaboard between Cape Cod and
DC. I still have room for the topo maps ofthe areas I cache regularly.
So far, I've only used SanDisk flash memory for all my electroinc devices
that use flash and I expect the 2 GB card for my 60CSx will also be SanDisk.
I seem to rememebr a discussion someplace that people using the faster speed
cards, really intended for video cameras and the like, in GPS units are the
ones having the problem. I don't know if that's urban legend or not, but I
have not had any problems with standard speed SanDisk in anything. No need
to tempt fate.
I just got the 60CSx yesterday and I've already swapped the 64 MB factory
card for my old 512 MB card. Not too big a deal and I don't anticipate doing
it too often either. While I'm still in the learning mode with it, it is an
easy switch over from my Vista Cx. Probably have all the settings cusomized
by tomorrow.

Congratulations! I'm sure you'll love it once you get used
to where things are on the menus.
