Hi all, I accidentally reach this thread while doing some reading. Surprised to c my lelong posting (selling GPS) is brought up here. smile.gif

Well, I've tested my GPS on notebook and HP Ipaq 2868 (with mapking) .... and I think its really helpful.

Just put the receiver on car dashboard, connect via bluetooth to PDA and hold the PDA by a holder and navigate around.

Further ques... PM or email me. smile.gif

Thr's 1 option in routing, you may set to 'recommended' instead of 'shortest route'

Thanks for the info. Reason i'm asking that question beacause I work in plantations sector (oil palm estate). It can be useful if I can use it for perimeter survey.

GPS can provide you coordinate... The rest of the features all depends of software you are using. Since u can plot the route u drive, you could calc the perimeter, area, etc (its all methematically solutions, u can even calc it manually)

Bout the accuracy, I would like to rectify my earlier statement bout the accuracy of my GPS unit. The stated accuracy for mine (16CH) is <7m (Non DGPS) and <1m (DGPS)

I attach herewith the tech spec of my product.

16ch means, it can connect to 16 satellites simultaneously. the more it connect, the better. gps needs at least 3 signals to get coordinate. its math. but normally, my 16 ch not even fully used. maybe not enough satellite up thr. hehe. anyway, i'm very satisfied with de accuracy already. smile.gif

can the GPS detect traffic jam? (like can we see the roads around us if there are many cars?)
No way, man. GPS detects ur coordinate, then realign ur coordinate on the digital map (software) on ur gadget. Its not a cam to capture image.

QUOTE(sniper msia @ Jan 8 2007, 04:10 PM)
one more thing. you said can reroute a better path. means the software oso shows direction of the roads? coz in KL those roads all like one way nia. sweat.gif

It depends on ur map software. As for my mapking, yes. It shows one way road. Whn auto routing, it knows way to guide u accordingly

ermmm how do u guys reset the gps??? mine is the one podo bought at garage sale................. i get soem misalignment lo

I believe its a temporary problem. Maybe the signal is weak, so, low in accuracy. Try to test it out in open space.

Once more thg, gps map normally has auto snapping function. Means, if ur detected coordinate is near to any road, it will put u on the road (it assume ur signal is weak and no auto correction by closest point) But if there are many roads nearby, it might put u on the wrong point.....

Just wanna share my opinions here because I have both type of GPSr

If you are planning to get a GPSr for light map browsing and navigation (on for a few minutes to find certain plc) and you are not driving, you may consider to get a Phone/PDA with GPSr / External BT GPSr.

But if you are heavy user where you depend on GPS technology to find your way while driving, by all means, get a Standalone GPS which is specially made for navigation.

Why?
1. Your phone has very slow processor/ram/storage/Smaller Display. Operationwise would be very unfriendly with slow response and you might have to press/tap many buttons before you could actually get what you want. If you are the driver, that would be even worse. You might have to get an assistant sitting beside just to operate your phone. And its a common thg if your PDA hang while u'r using the navigation software with many other software running behind
2. While in busy roads/highways, you are finding your way using GPS with your phone, in critical turning point, suddenly a call comes in....haha....
3. Phone/PDA normally has a short battery span, so, save your battery for your calls. For bizman, calls means money! smile.gif
4. And 1 more very important issue is, some phone uses GPRS (its GPRS, not GPS) to download maps. GPRS downloading.... if you dont have an unlimited data package, u wont know what is the amt printed on you mobile phone bills at end of the month. Sigh....
