Hi rockminder,
I agree about the built-in SPOT feature. That's sure attractive for those of us who like to disappear into the outback from time to time.
You might also want to take a look at
Garmin's Birdseye Satellite Imagery. They are trying to catch up with a feature that DeLorme pioneered with, I think, the PN-40 ... to have the ability on the device to display raster images and a service to select and download the aerial imagery you want.
I don't know what Garmin's aerial coverage is like because my eTrex Legend HCx won't display raster images so I have no interest at this point.
I would sure change my tune if they would release a version of Mobile PC on my laptop that could display raster images!!! (Are you listening, Garmin???)
Anyway, you might want to get a Garmin handheld that is capable of using this feature in case you might want to take advantage of it in the future. Much like with Garmin vector maps, there is already a bunch of knowledge out there about how to capture and use your own raster images for the Garmin devices that can support them. As I mentioned above, the Groundspeak tech forum at Geocaching.com also has a wealth of information about this feature and how to take advantage of it, too.
By the way, when you are talking to a local Garmin dealer you need to be sure you understand exactly what they are talking about ... because sometimes they don't have a clue. For instance, are you aware that the GPS400 and GPS500 are aviation units? The GPS400W is one of the cheaper ones and it's over $8,000 dollars (yep, 8 followed by
three 0's.
It's designed to install into the dash of an airplane .. comes complete with the basic wiring harness. ... Hardly something you want to go hiking with.
Also, you might want to verify what they mean when they say those devices will "take topo" some day. If they are talking about the avionics devices like the GPS400, etc., what they probably mean is that they will be upgraded so they can use standard roadmaps. Most avionics units use a basemap, terrain maps and the Jeppeson navigation database but do not use roadmaps. Any that will use Garmin's standard vector roadmaps will also use Garmin's topos or any Garmin-compatible maps.
On the other hand, if they were actually talking about the 400 and 500 model of one of their popular hiking handhelds like, say, the Oregon line, those devices already "take topo". That is, they will allow you to load and display any Garmin-compatible vector map like the ones I mentioned previously from a variety of sources. Those include topographic maps. There isn't a single handheld device in Garmin's line that won't let you load and display topographic maps. Some do a better job than others. But they all do it.
So in that case, they were probably talking about an upcoming upgrade to allow them to load and display the Birdseye aerial imagery I mentioned above, which is raster images rather than vector data. None of their older models, and not many of their newer models support raster data. They are adding the feature to many of their new models and providing software upgrades for some of the newer ones that have the hardware ability but not the software feature. If I was buying a new one and wanted the feature, I would buy one that comes right out of the box with it rather than mess with an upgrade that might or might not have some limitations.
I hope that all made sense to you. And I sincerely hope that you and your local Garmin folks were all on the same page and they weren't just trying to blow smoke up your kilt.
