The standalone GPS units have no video input of any sort.
Your short answer: No.
Hey there people,
Okay, first of i have search on this one for a little bit.. Usually my keywords are not to bad, but i could be having a bad day as any. So anyway, it to what i have been curious about for the past 20 minutes or so..
GPS Units, As in the handheld/car/portable units that are sold from most car places. Navman, Garmin, TomTom and all the other brands. Most of these have a USB interface or other means to connect to the computer and operate a form of Windows CE. Cut down from what i could see on most.
Is there currently a project, software or something out there about a two piece application and or driver setup that allows a networking screen display. So being able to share the screens either way, I'm mostly curious about getting the control of the GPS unit.
So for an example, XP being the CarPC. CE being the GPS Unit..
Having the CE comp showing a fullscreen menu/app generated from the XP comp, Then the user would respond with a touch or two of course then the mouse X,Y are sent to the XP comp to respond so forth and load or generate what ever needs to be. So extending your GUI to a networked or possible driver controlled external USB device.
The other part of this i did wonder about would be being able to also hook into the GPS receiver and use this with any application or to which ever level. So for people who say have GPS unit laying around already that seems of no use or are current running a separate GPS device as no USB module/dongle.
Dont get me wrong, it could already be out there.. A waist of time or no use, but its a thought that i had a quick look into and thought would share on here?
So your saying that a windows CE device can not be networked? Does not need a video input such as svideo or that, Just the ability to draw pixels.
And I never said that a WinCE device couldn't be networked.
However, what you're talking about is not networking. You want to use the touchscreen of a standalone device to show the display of a PC and control the PC with a touchscreen.
I will say that it's possible to pull off. Here are the steps you'd need to take:
- Open up the GPS unit, voiding any warranty.
- Figure out how to get video to the screen.
- Reverse-engineer the touchscreen mechanism to be used as a HID-compliant device for the PC.
- Wire the touchscreen and the video to the PC. Understand that you'll likely be limited to either display & control of the GPS or display & control of the PC, but not both.
- Potentially code drivers for the touchscreen to use on the PC.
There was a user on here years ago that did this with a Kenwood in-dash unit. The general consensus is that such feats are possible, but hardly practical.
In addition, the screen of most standalone GPS units is pretty tiny, making use for a PC extremely limited and difficult to use. Modern Windows-based PCs are designed to use a pretty high resolution (800x600 or higher) and you won't be able to get close to that on a 5" screen.
Long time ago i had a wince PND not anymore and used to display it to my pc using something called cerdisp.exe,cerdisp2.exe or ftpdce.exe,cerhost.exe,RemoteDSP or WindowsMobile Power Toys that i already forgot which one...just search with those related words and hope you will find one.
But not sure if this were something you looking for.
was thinking more of simply getting them networked, then having two apps running like a client/server which will transmit the data as needed.. Sort of similar idea in mind with MaxiVista
CE will have a custom build app that will generate displays based on HTML or something scriptable and will send back mouse xy.
Screen size is to be used more of as a miniature control panel,
EDIT:, Cheers bandung_steve.. Will have a google now
