@lkmnb,
Is urs a proper aka legal version of Sygic?

Yes.. my experience.. Sygic won't able to work at in door (won't able to detect GPS signal).. Walk out of the building and get a clear sky.. Immediatelly u will get GPS signal & your current GPS location... It is not iphone problem, but it is more on Sygic... As if i use native googlem map in door, google map able to detect my current GPS location...

can i ask if use bosspref disable edge and 3G to prevent my iphone to use any data usage to avoid charges, so will my MMS work?

Yes, because i tried that myself.

oh nice then.. so no worry bout accidental charges on data already. thx for clarify.

Used both Sygic and Navigon in UK. Concluded Sygic is a crap and Navigon win hand down.

Sygic UI is so confusing with icons organized all over the place and finding it is rather difficult.

Navigon is very easy to use and UI is iphone based. So it works like any iphone app.

The only complain with Navigon is the voice is not very clear but lowering the volume seem to help.

Both can be used without incurring data charges.

But I am waiting for TomTom to be launched soon in UK.

I will get the TomTom car kit that offers secure docking, enhanced GPS performance, clear voice instructions and hands-free calling, while charging your iPhone at the same time.

IPhone 3G does not have a dedicated GPS chip, and instead uses A-GPS to triangulate it's position, is this the same on the IPhone 3Gs? or does it have a dedidcated GPS chip?

mate the I3gs too uses A-GPS and so does major models of HTCs , O2s and nokias with gps function..

well based on my understanding the a-gps works just like a normal gps but better in the sense that it can use a network to locate places instead of the gps receiver alone..which makes things alot faster..

in these phones there are gps chips..just like any gps device..basicly if im not wrong, without any network the A-GPS will work like a normal GPS system..

initially i thought the a-gps was network dependent but i have come to an understanding that its not..

I just don't know why people don't do their research first about GPS and A-GPS. A simple google or search in wikipedia would answer that (btw Spoodo, your understanding/fact on A-GPS are WAYYYYYYY OFF)

A-GPS are not below or less than GPS infact it's superior to GPS alone. A-GPS uses cell triangulation + GPS satellite locking to get a faster location than just normal GPS.

And to answer your question, YES, the iPhone 3G and 3Gs have a GPS chip in them, a dedicated one FYI.

GPS = only use GPS chip to lock on to the satellites
A-GPS = use GPS chip and assisted (thats what the A in A-GPS stands for) by cell tower triangulation to get the lock faster

Capish (donno what dat means, click here)

it's not that i didn't do my research. i know A-GPS uses cell triangulation to achieve better satellite tracking as compared to a normal GPS chip. I got confused with a statement on wikipedia which stated that the IPhone 2G has to use it's cell information to determine it's location due to a lack of a build in GPS hardware. Although this is not so in the newer 3G and 3GS due to the A-GPS, but since i know there are so many knowledgeble gurus here, i would just like to clarify or gain a better understanding. there's nothing wrong asking right? Isn't what this forum is for? Anyways thanks for your clarification.

Elusive: Yeah, initially i was in a similiar position as you. Thanks for the info!

Spoodo, no worries, the fastest way to get a correct answer to your question in this and any forum is to make a wrong/inaccurate statement, whether intentionally or not. Sometimes it's better than just to ask a straight question. You find a lot of people correcting you, myself included. :-)

Google maps won't be able to detect your location using GPS indoors either. What you are seeing is the approximate location based the "A" portion of the A-GPS (i.e. using cellular data & approximating based on nearby comms towers).

Anyway I had a moment of utter frustration with Google Maps last Saturday. Needed to attend a function at Malaysia Tourism on Jalan Ampang. Since the location was available on Google Maps I didn't bother doing any further research on where the place was.

Turns out the location based on Google Maps was WRONG! The actual MaTic place was about 1km on Jalan Ampang nearer to KL than the info on GM, made me late for my function by about 15 mins after frantically calling up people & trying to find a map online. Zzzzz.

Downloading the maps doesn't really take away a lot of data,
But it drains your battery VERY VERY FASTLY!

Hours, I mean, on 3G network.

hehe...battery wud drain alot alot faster if 3g is on...

Just to share

ow much for an iPhone-powered TomTom satnav? That's the question that has been on the lips of many an iPhone user ever since TomTom announced it was developing a version of the market leading turn-by-turn satellite navigation system especially for the iPhone. Now, it seems, we are a little closer to knowing the answer. I just hope you are sitting down before I reveal it.

According to one online retailer which has broken ranks and gone public with pre-order pricing, if you want an iPhone-powered TomTom satnav in your car it will cost you a cool £113.85 ($193.75) or which works out to £99 ($168.50) plus tax. Which is not, by a long shot, the most expensive iPhone app.

Now before you reel too far back in absolute horror, that isn't the cost of the maps and satnav software alone. In fact it's the price for an in-car kit which includes the software (with the latest Tele Atlas mapping and the TomTom IQ Routes feature) plus a specially designed, and I have to admit rather sexy looking, cradle which provides secure docking, enhanced GPS performance, voice instruction sound boost, hands-free telephone calling and in-situ charging of your iPhone.

In fact, a quick scout around the same site that has published that pre-ordering price is selling the cheapest standalone TomTom in-car unit for £118 ($200) which means that the iPhone version is actually cheaper, assuming you already own an iPhone 3GS that is.

Currently TomTom are neither confirming nor denying the pricing, or availability for that matter, other than to say that the cost is to be confirmed and the iPhone satnav should be released this summer.

Of course, the TomTom software application itself will also be available from the Apple App Store as a standalone download for the iPhone, and one has to assume that the cost will be fairly dramatically reduced if you are not buying into the hardware kit as well. Certainly one would hope that it will swing in lower than the only real competition at the moment, the Navigon MobileNavigator for iPhone which is currently being sold at a reduced price of £59.99 ($102) for the European maps version until the end of August when one assumes it will zoom back up to £79.99 ($136) - you also have to assume that the timing of the price cut is to try and ward off the inevitable TomTom effect. Which does, indeed, bode well for a release some time later this month.

There are still some questions to be answered, such as will TomTom for iPhone be Homer Simpson powered and how will the in-car kit deal with the 3GS getting hot issue considering Apple has already warned about leaving the phone exposed to heat through car windows.

It will be interesting to see if the new TomTom software developed for the iPhone can actually use data for traffic reporting. If so, I might just be tempted to invest. My wife has had her eyes on my TomTom Go530 for quite some time, so all being well I might just have solved the what to get her for Xmas problem - and, no, I don't mean the iPhone car kit!

For those who is using Sygic Map, I just wonder that how fast can you detect the GPS signal? My sygic sometimes takes 3 mins to detect, sometimes cant detect at all... Could I be the location or the cloud affected the signal?

My sygic needs a strong GPS signal to be able to detect my position. It detects quite fast actually... about 10 - 20 seconds. If i'm under any roof for example then the signal gets lost.

so far i've used tiwice and sygic was able to detect signal in less than 30seconds...but the thing is i've turned off EDGE and 3G (using bosspref) and when i check my data usage via settings i can see data being used up. Anyone experienced this?

Mine experience was not good...sometimes it cant detect at all...I am not sure is it because of the Haze in Penang..

ya sygic is crap.. even if u get the signal, its very bad.. normally i already pass the turn then it says " turn left turn left"... zzzz.

unlike garmin on n95, always correct on every turn..
im looking for other alternatives now.
