You mention maps, but fail to mention that:You can also get/make custom maps for Garmin.
The PN-40 works with DeLorme's xMap software line.
The Triton 2000 has Triton RMP Creator & TritonRMP Helper and will also run Ozi Explorer CE. TwoNav Pocket will also run on Windows CE/mobile devices.
Are you wearing your "GARMIN put the G in GPS" shirt or what?

Thanks, I'll give their forum a look.
Maybe. There have been numerous reports of spontaneous shutdowns and problems to power back up on the PN-40. Very often it's temporary; just leaving the device without batteries for a few hours sometimes resolves it.Are you saying that the unit bricked because you let the batteries run down?
No solid explanation but quite a few theories among the user community, and there may be more than one cause for what looks like a related batch of symptoms. Lots of ongoing discussion as pinned near the top of the DeLorme PN40 forums...

Nice rundown, how are the units construction wise?

No cracked screen? Maybe the small demon inside has a heater.Right, well here's the result of the first part of my freezer test of the PN-40; chilling just the device but not the batteries for several hours: No difference. The screen might have taken slightly longer to come on, but no obvious slowdown or problems with brightness.
Next test, a little later -- will be with chilled batteries.
I have no doubt that cheap batteries suffer from cold, but I still can't get that to fit Briansnat's observation of the screen redraw slowing down. A GPS is not a tape player -- low batteries shouldn't make it slow down. I'd expect it to give a low-battery warning or just shut off.
Unless it works like some of the gadgets in Terry Pratchett's Discworld? A small demon lives inside the GPS and paints the maps for you... but the poor little imp slows down when tired, hungry, or cold

Yes, I read it fully twice before I posted the link. The comment I made was about the PN line, feel free to reread my post. In any case I'm not interested in their PC or PDA based solution past or current, I have a PC based solution, I'm looking into a stand alone handheld solution as per my original post. And while their subscription service is a fair deal for the right person, it isn't anything I am interested in.Wikipedia has them coming out with the PN line in 2007, with the company forming in 1976. So it looks like that hardware line is relatively new to them as a company.If you read through that link, you'll note that it was 2007 that they introduced standalone handheld units. They've been doing PC- and PDA-based GPS for nearly 15 years.

I'll give those a look. I remember that DeLorme made maps, didn't know they now had hardware. Have you used their system?I'm looking to get a good handheld GPS that has the ability to load geo-referenced images, such as map scans and/or georeferenced imagery along with vector data. Simple enough.
You've just described the DeLorme PN-series devices in conjunction with XMap (if you're using your own images, instead of just what you get with the $30 map library subscription).
I've owned a PN-40 since February and have very few complaints. I don't use custom georeferenced imagery though, just the stuff that they make available through the map library.
They've been making GPS devices for quite a few years, actually.

It the unit is rated at that temperature then it shouldn't be a problem.You could always stow your gps overnight in your freezer and check it in the morning, no need to wait until winter
Excellent way to crack the screen, too.

It has a SiRF Star III GPS reciever so it has more than 1 channel. Maybe "Yes" is the answer for "Comes in pink?"For 80 bucks? I don't know this system that well. You can pick up an older well known unit for the same price.
Someone's definition High-Sensitivity Receiver may not be that accurate. Even just the AAA batteries make me cringe. And what the heck is 'Yes'?

That's a hypothesis we can test....I would have to point at an inferior battery type as the culprit and not the screen.- What affect does low temperature have on "inferior batteries"? Reduced voltage?
- Is the PN-40 known to slow down screen redraws at low voltage?
-
Did you place it inclined against "a rock or something" when heating it?I opened a 2005 chicken tetrazzini* this past weekend and passed on the shake because of this recall.
The chicken was fine, though as hot as the Flameless Ration Heater got, the food was only tepid.
* it came from a batch from last year, but according to the menus I've seen, it was a 2005 one.

I'll give that site a look, thanks. Betting that they are pretty much one sided?

The TwoNav Aventura looks pretty good, but there are other units that look a little more robust such as the Magellan Triton 2000 or maybe the Bushnell ONIX400. I have heard that the Triton 2000 can run OziExplorerCE, so I would guess that it should also run TwoNav's Pocket software, so I'm not so concerned about the bundled Magellan software. I haven't heard very much about the ONIX400, so I don't know if one can only use their downloaded maps or what.
In any case, I think that something like a Trimble Recon might be overkill for what I need, but if it came to be the right tool for the job, so be it.
If anyone here with any experience with any of these units that can toss in their thoughts it would be greatly appreciated.
Thanks in advance.
