Would be quite an advance in the Discworld. Imps work inside of cameras and "personal disoganizers" (equivalent of a PDA), but I don't think there's a DPS (Discworld Position System) yet. Sadly, Terry Pratchett has Alzheimer's, so it's possible Discworld technology might never advance much further than the clacks. I think I have a team of them in my Toughbook .

You mention maps, but fail to mention that: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?

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. 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... http://forums.delorme.com/viewforum.php?f=131 Thanks, I'll give their forum a look.

Nice rundown, how are the units construction wise?

Are you saying that the unit bricked because you let the batteries run down?

No cracked screen? Maybe the small demon inside has a heater.

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. 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.

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'll give those a look. I remember that DeLorme made maps, didn't know they now had hardware. Have you used their system? 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. 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. http://en.wikipedia.org/wiki/DeLorme

Excellent way to crack the screen, too. It the unit is rated at that temperature then it shouldn't be a problem.

It has a SiRF Star III GPS reciever so it has more than 1 channel. Maybe "Yes" is the answer for "Comes in pink?"

That's a hypothesis we can test. - What affect does low temperature have on "inferior batteries"? Reduced voltage? - Is the PN-40 known to slow down screen redraws at low voltage? You could always stow your gps overnight in your freezer and check it in the morning, no need to wait until winter

Did you place it inclined against "a rock or something" when heating it?

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

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. 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. -JD-

I didn't know there was a test today
