Garmin MAP transferring is dog slow

        I don't have any need to transfer the mao from computer to the 8GB SDHC
Class-6 memory card, but 1-1/2 day ago I give it a try... and man, it's much
slower than I have expected.

        After around 36 hrs transferring from hard drive to Card Reader and it's
only 65% done. And because it uses nearly 90-98% of CPU which causes
slowness to the whole system, so in the first 24 hrs I lower the Priority to
"Below Normal" in order to run other aps, then switched back to "Normal"
about 12 hrs ago which helps to speed thing up a little but not much.

        Why MapSource is too slow is beyond me, I have been using computer for
around 3 decades and this is the very first time I run into this dog slow.

        I am running WinXP, AMD 4800 (around 2.4Ghz) and 3G memory, and using
Memory Card reader by Transcend.

What are you doing? Tell us some more details.

Have you selected some map segments in MapSource and are uploading them
to the card in a reader?

If so, how many maps (segments) were selected (the figures are at the
bottom of the Maps tab)?

What is the total size of the selected maps?

What products were the maps selected from?

Tell us all that and we can probably tell you what the problem is. The
behavior you are seeing is not normal.

Also, last I knew, Garmins had a limit of 2 GB or 4 GB on SDHC cards.
That limit seems to vary with the GPS model involved and the version of
MapSource you are using.

You might want to call Garmin at 1 800 800 1020 and see if the tech
folks can confirm that your card is okay for the use you intend.

        I just select the whole Garmin Topo 2008 and tell MapSource to save to a
memory card from memory card reader. Just ONE MAP.

===============================================


        It's just a test so I don't pay much attention to the segments, but it
says something about 3.xGB of data


        About 3.xGB of data (probably around 3.3GB?)


        Because unlike City Navigator, MetroGuide etc. I can't select the BLOCK
(segments) one by one, so I selected the whole thing (USA). And I selected
using MapSource of course (as I mentioned in the original message).


        I may try again, probably City Navigator 2008 see if it will make any
difference.

        BTW, I have transferred smaller segments (around 2 states) to 128MB data
card and it won't take more than 20-25 mins. But 74% for almost 48 hrs is
way too much.

        And it eats lot of CPU resource too (looking at the Task Manager). It
just doesn't sound right.

Hi,

that won't work. There is a 2025(+/-) map file limit. You need to select
fewer Topo maps. I believe the whole TOPO 2008 has about 6000+ map parts.

Maybe Jack can explain it a bit better.

The problem is probably that you have too many maps or segments selected.

There is an undocumented limit on the number of map segments that can
processed and uploaded from MapSource. The maximum is 2,025 segments.
If you selected all of Topo 2008 I think you have selected something
like 6,600 segments, no?

I have the previous version, it was called U.S. Topo. But I think Topo
2008 has the same number of segments in it as did U.S. Topo.

My version has the topo mapping divided into four regions, East, West,
Alaska, and Hawaii. East and West have more than 2,500 segments each,
Alaska has about 1,500, and Hawaii has less than thirty.

Regardless of how the segments are grouped in Topo 2008, you cannot
upload more than 2,025 at a time. And when you try to do it the process
slows down grossly and might not even ever finish. If it does finish
the map file might not work in the GPS. If it does work in the GPS it
will not have all the segments you selected in it.


Well, I guess maybe you going to have to start. If I select all the
segments in my version it totals out to 6,639 maps totaling 1,795.8 MB.

How many maps and what size does Topo 2008 total out to? If the size
has nearly doubled they must have added a lot of stuff to it.


Why can't you select them one by one? Maybe there is something about
Topo 2008 I don't understand.



City Navigator only has about 350 segments, or 50 if you have the NT
version. U.S. Topo is the only mapping that maxes out over the 2,025
limit.

To travel with all the topo mapping you have to divide it up onto more
than one microSD card. Or use one of the other workarounds to beat the
2,025 limit.


You're right. I learned it the hard way too. It is one of the rites of
passage for using MapSource. Garmin is not renowned for having
excellent documentation or excellent software either one. The only
things that are less excellent than those are their product pages. A
decidedly most unexcellent company on the whole. But they make pretty
good GPS receivers.
