I'm planning to buy a set of City Navigator maps for my new Montana 600,
which are available as a download or a DVD.

I was about to specify the download to avoid delivery delays until I read
this page on the Garmin website:
<http://tinyurl.com/ygk6r96>
According to this it appears that updates can be obtained for the DVD version
but not for the download. Can anyone actually verify that this is true? It
seems such a pointless and arbitrary restriction that I can hardly believe it

That's Garmin for you. Yes, it's true. I wanted to download City
Navigator and use it in Mapsource. No go. Download to device ONLY.

No wonder people use GPS functions in smartphones instead.

To answer my own question, I telephoned Garmin support to ask them about this
and the answer I got was this:
Yes, it is true that you can buy updates (either one-off, or a lifetime
payment) *if* you buy the original on DVD but not if you get the download.
The explanation (which I'm not entirely convinced by) was that the download
is supplied as a complete image file for the area you specify, which is
downloaded directly onto the unit. The only way (it was said) it could be
updated was to replace the entire file with a new image. The DVD version on
the other hand was supplied as the individual area tiles which are installed
on your computer which are then compiled into the final image by the
installation program also on the supplied disk.

As I said I'm not entirely convinced as I would have thought some update
scheme could be devised for whichever format you chose. However at least
there *is* an explanation and it isn't simply arbitrary as it seems. It's a
very good reason *not* to specify the download version though, as the price
is the same and the only disadvantage of the DVD is the time taken for
delivery.

If this is true, it's an artificial/business decision and not a
technical one. If anything, downloads make it easier to replace parts if
you create a rudimentary versioning system and/or servicing stack.

However, none of this changes your options once they've made the
decision.

When installing from the DVD, the map version on the DVD is compared to
the version on the Garmin website. If the online version is newer, you
are given the option to download the latest version or stay with the one
on DVD. If you purchase it online it *will* be the latest version, so
no update is necessary. In any case, you get the option to get the
latest version. Any further updates require another purchase. I did
the online update from the CNNA DVD and it DID put the maps on my PC also.
NuMaps Lifetime allows updates four times per year for the life (as
defined by Garmin) of your GPS for one purchase price.

Hi,

Yes, but the load on the download server would be a denial of service attack
whenever a update was announced for the new image (s).

Compare the loads for the updates for the DVD version Vs the download
version.

The DVD updates must be much smaller and the new image updates oh so much
larger.

My GPS is a DeLorme PN-60 so I have no idea of the actual update file sizes.

Ever camp at Spruce Grove Campground 39.58279 -122.93447?

It took my Garmin 12XL to find it.

Yes, but I was thinking of future updates in (say) a year's time. With a
download, your only option would be to buy a new download at the full price.
If you get the DVD version (as I understand it) the same update policy
applies as with a pre-installed map.

Again, this is an implementation difference. If they wanted to avoid
recreating their environment more than necessary, they could distribute
the download version as a DVD image (ISO format, for example) and use
the DVD-download patches to handle updates.

A better solution would treat the maps as modules and allow them to be
superceded, only downloading the parts that actually changed.

When I purchased a DVD a prompt on the screen said if I didn't opt for
the online update at the time of installation, I would not be given an
opportunity to update once the DVD version was installed.
