Live GPS tracking

This is my first post on this forum. I hope I haven't picked the wrong place to ask my questions. This seemed like the best place to start.

I am interested in doing live tracking in my vehicle with my GPS. National Geographic make a product called TOPO!. It is comprised of USGS maps (the only topo mapping using USGS info) covering all of the USA. With a GPS hooked up to a PC (laptop), which is running the TOPO! program, you can follow, (real time) your path as plotted on a USGS map. I travel off road and need the detail of the USGS maps.

I have a Kenwood KVT 911 DVD and KNA 3100 navagation system in the vehicle now. The unit has a flip up screen which the manufacturer says can be used as a monitor.

I would like to install a remote PC, which I am told is an ITX (???), in the vehicle which can allow me to do what I would otherwise need a laptop to do. I would use the existing Kenwood screen as the monitor. Any help would be appreciated. Thanks!

ITX is just a formfactor for motherboartds, nothing more. Many enthusiasts prefer the miniITX formfactor because of it's small size.

ANY PC can do what you want. Howrever, you're going to need a mobile internet connection, probably through a cellphone carrier.

You're also going to need a PC-compatible GPS receiver, as the one in your Kenwood setup isn't going to interface with the PC.

Also, you would need a PC that can output composite video to get the image on your existing Kenwood monitor. You could use a scan converter, as well.

I take it then that I need a miniITX?

Why? There is nothing that I would need from the internet while live tracking. Besides where I go, often times there is no cell phone signal from any carrier.

Already have a Garmin 276C which is compatible. The Kenwood is just being used for the screen as a monitor.

Translation??? Thanks again.

Translation: Google "Scan converter"

A computer outputs VGA. That's much higher resolution and a different standard than your Kenwood screen can display. The Epia M10000 mini-ITX has a composite video output that you can plug into the Kenwood.

Be aware that the picture will be fuzzy and it will be difficult to read text unless it is fairly large.

I never said that. I don't believe I even implied that. And there is no such thing as "a miniITX".
Do you need a miniITX formfactor motherboard? No, not at all.

I'll reiterate: Many people prefer the miniITX formfactor because they are small and most of them have a very low power draw.

IS this for someone else to be able to track you? If so, how do you expect to get your GPS coordinates on another computer?
If it's for your own use, you don't need the internet connection, to be certain. If I misunderstood your post, I apologize. When I heard "live GPS tracking", it implies that another person can see your location at any given time.

Nothing to translate.
PErhaps you need to learn about video connections first. Try checking this out: http://www.mp3car.com/vbulletin/faq-...strations.html

Amd, as Bugbyte stated, Google is your friend. Use it wisely and it will serve you well.

Well, when you said that many enthusiasts (I am an enthusiast) prefer the "miniITX" due to its small size (obviously a requirement for vehicle mounting) it sure sounded like you were implying that I might need such a thing. If I wasn't an enthusiast and I wasn't interested in the small size I would have purchased a laptop and wouldn't be posting here. Don't mean to put words in your mouth, but I just interpreted your words using commonly understood definitions.

Funny, I just used your terminology. Excuse me if I forgot to add "motherboard". As you might have noted from my first post, I am new and am trying to learn. Chastising me for omitting a term which I don't understand seems like a good way to get me to leave. If thats the case, I'll comply.

No, as I mentioned in my original post, I am interested in observing my tracking in my vehicle. If I need to obtain another vehicles position I will utilize APRS over my Ham radio.

What you mean is you want to display your GPS position on the topo maps using a PC. That is trivial.

1. Buy laptop
2. Buy GPS
3. Buy Topo! or TopoUSA by Delorme.
4. Buy car adaptor for laptop if you don't want to run on batteries.

Done.

If you want to do some more advanced stuff like installing a touchscreen, integrating the system into your car and so forth, a good place to start is with the link in my signature to the FAQ emporium. For a good overview of the various topics you may want to cover, check the wiki from the link at the top of the page.

There's a HUGE difference between live GPS tracking and GPS navigation. I guess you need GPS navigation?

I am using the terminology which National Geographic uses. LIVE TRACKING means, in their lexicon, observing your progress as plotted on a USGS map. Which is what I want. I do not need navigation.

I'll clarify:
Many users prefer to use motherboards with the miniITX formfactor because they are small.
They are hardly necessary, so long as you have the space for a motherboard with different (and larger) formfactor.

Personally, I have a motherboard that uses Shuttle's proprietary formfactor, which is about the same size as flexATX, yet nother formfactor.

Basically, my point is that you can use damn near any computer hardware in your vehicle. You're only limited by how much money you have to spend and how much time and effort you're willing to put in (or pay someone else to put in) in order to make your hardware fit & work properly in your setup.

My point is that there is no such thing as "a miniITX".
There is such a thing as "a miniITX formfactor motherboard".

Does that clear up what I was trying to convey?

It's similar to the difference between "I have a red." and "I have a red ball." Which one makes more sense?
I promise you that if you were to walk into your local computer store and tell the salesperson that you want "a miniITX", they would correct you as well. Depending on the shop, they might also laugh at you. We're not doing that here...

OK. Subsequent posts have made this clear, I believe.
Understand that typically we think of "live GPS tracking" as the ability to remotely see someone's location based on GPS data that is sent to some repository, typically through the internet.

GPS navigation is the plotting of current lcation on a map and interpolating the directions you need to follow in order to get to a specified destination.

Based on what you've said, you really don't want either. You just want to see your position plotted on a map, using the GPS data. That's pretty simple, so long as your map application has the ability to plot coordinates from GPS data. You said that it does, so you're set there.

I believe that you may also want to have the ability to plot your route after the fact in your map softare, as well. If this is the case, then you may want the ability to log the GPS data or possibly the route from your topo map program. This might be a bit trickier, but certainly doable.

There's a lot of it to digest, I assure you!
PAtience, planning and asking of relevant & intelligent questions will yield good results.
