Hi everyone,
I am about to buy my first PDA/phone, and the choice boils down to either the E-ten X500 or the HTC P3600.
The E-ten has got the lead where GPS is concerned thanks to SIRFIII but the 3600 has UMTS/HSDPA...
I have read as much as I could on the Qualcomm chip that is used in the P3600 and since the GPS feature is very important to me, I'm worried that the P3600 is not the way to go.
I would therefore like to ask your findings in the GPS usage, not only in Time Till First Fix (although ofcourse very important), but also in keeping the fix, re-acquiring a lost signal, etc...
Have a S300+ (french vodafone version) with the original ROM and Radio version and for me it's less than a minute.
Hi,
TTFF is impossible under 30 sec (except A-GPS), 30 secs is the minimum to acquire ephemeride in good conditions.
If you are searching the best sensitivity, sure, take the ETEN (sirf III) !
But, with my french Renault Clio and its athermic heat shield, no big issues, no delay over than 10 meters, even in city, hot start less than 5sec (tunnel exit).
So really happy, it's nearly like a BT antenna (in same conditions)...
I will post tomorrow some pics showing differences between radio 1.38.00.11 and 1.41.00.11 on the same route, there is no changes in quality so all people can upgrade to 1.41.0.11 (for the gps part)
hi I have a P3600 and a separate Rikaline 6033 BT GPS. "the only 32 Parallel Channel GPS receiver in the world - Uses the latest Fujitsu Japanese chipset giving excellent precision
- Superior than the Sirf III Chipset with greater sensitivity and lower power consumption"
I can say (marketing blurb aside!) the Rikaline is a superb device, and the P3600 is almost identical.
It finds a fix very quickly from cold (unless in a moving car) and the sensitivity of the P3600 seems to be nigh on identical to the Rikaline BT device. I did own another BT GPS for a short period of time - but found the sensitivity poor so returned it for the Rikaline.
I have to say the P3600 is a great solution. My only gripe is to do with the poor Voda 3G coverage in the UK.
I would say that phone reception is slightly better on my M600 - but that's going on number of bars in the signal strength....
Please put the full name: "Time To First Fix" I guess in addition to the abbreviation (TTFF) in your vote
It can be : Trinidad and Tobago Football Federation or something esle
We are in a PDA dedicated forum... and not every body is suited to understand such GPS abbreviations

thx for the great info!
Can anyone back this up?
The reason I ask is that it is generally accepted that SirfIII is better than the Qualcom, and from a technical standpoint I can understand and accept this. However, if usage on a day to day basis shows equal or near-equal performance, I could care less about reputation and would go for the P3600
Hell, some might argue that if the Qualcom gets the job done with less sattellites, it's actually a better solution for it
On the other hand, I already put an offer in on a used X500 and can't seem to find any decent priced used P3600's where I live, so that might end up being the deciding factor anyway. But still, if the GPS is fine and I do get a chance to purchase a used one, I won't hesitate
If it can help :

I disagree with this test !
Got the S300+ SFR, and it works like a charm !
Depend of the radio version etc...
I already saw that one but thanx anyway
Actually, that was the review which caused me to start doubting the P3600 as far as GPS is concerned
The problem is that the only thing that is translated into real-world usage in this review is the slow Time Till First Fix they mention (though this is not reflected by the poll here I must say...Maybe thanks to the radio updates in the meantime...).
It does not really answer my questions on how GPS usage is affected on a daily basis.
Ok, there is deviance from a set route and you can witness that on the tracks they map, but how does this translate into the real world?
Does it point you in the wrong direction a lot?
Is it slow in giving you the right directions because of a more latent signal?
Does it lose its signal a lot?
Does it not reconnect quickly after connection is lost (tunnels and such)?
From what I'm seeing here on the forum (or from what I am not seeing actually: complaints ) this GPS seems to perform just fine so what is the relevance of the findings of the gpspassion comparison?
I'm not questionning these guys' work though, they seem particularly tech-savvy when it comes to GPS and I appreciate what they do.
But I'm starting to wonder in how far the SirfIII is actually any better.
I just set an appointment to pick up the X500 this weekend though, so if you guys are going to stop me from buying it, the window of opportunity is fading
I don't doubt that the X500 has better GPS but I'll never own an ETEN product again. Go with HTC.
Argh....we've been down this road a lot on this board already....
There's no actual winner here... I've used both a BT GPS mouse and now the Qualcomm in Trinity, and i can tell you there's no notable difference in the normal usage scenario's...
But hell...if you wanna start a chronometer everytime you fire up the nav, go right ahead Does it make you feel better if either one turns out to be just 5 seconds faster than the other ?
The P3600 is just as excellent (if not better) in keeping the fix and reacquiring it, it's got HSDPA/UMTS, it's already got WM6 by now, and just looks freakin' good as opposed to the freakin' ugly E-Ten...
Am I biased ? Hell no....

Looking at that review it appears they tested it in an 'urban canyon' - city with lots of tall buildings type scenario. In that environment it is no surprise that the SIRF3 outperformed the Qualcomm chipset.
So whether or not it will work for you depends what the environment is like that you'll be using it in. If you are spending a lot of time in a city with lots of tall buildings and short streets (ie you'll be turning a lot) then maybe a SIRF3 based device is for you. But if you spend most of your time in the suburbs or open space then don't worry, the difference will be negligible.

My answers to your question would be no, no, no and no...
Having used both a SIRF3 BT GPS module and the internal GPS on the Trinity I would say there is absolutely no difference in performance in the environment I use it in, which is mostly suburban driving with occasional trips into the city.
Also TTFF I found was negligible between the 2 - cold time was ~3mins on both, warm < 30s on both.
Only real difference I noticed was that inside my house I can get a fix on the SIRF3 in most places, with the Trinity internal GPS I can only get a within fix 1 - 2m from a window. But since I don't have much use for the GPS inside this is kinda irrelevant!

Hello:
my answers are NO, NO, NO and NO.
I get a faster fix when I'm not moving but it is always under 2 minutes (always with TT6).
The whole "fix-discussion" depends on where the satelites actually are and how many of them are "available" in the sky...
I did not recognize any differance between the radio roms for the GPS...

No at all... (No signal lost, No wrong direction, No slow redirection, No slow reconnection ...)
For me, It is my first GPS... I never had one before, so I can not compare.
However, this GPS does not have such problems.... and works really perfect for classical/personal use.
I am using it extensively for months, and It fits all my needs and expectations.
Also, I do not have any experience with Eten.
But for me... the HTC Trinity is the best and the most complete communicating PDA never constructed
Now we're getting somewhere!
Thanks all for your great replies!!! Keep 'em comming
I'm starting to think about cancelling the X500 now damnit
Just when I thought I had it all figured out....

Hi....Just wondering, because my contract with o2 just finished and I was looking for a replacement for my XDA Mini S...and what's the best phone for me now . I'm looking for a 3G phone, with built in GPS, WiFi, fast processor and good looking one (for my pleasure only, not to show up ;p ), which fits into pocket and, and, and...I was thinking about XDA Orbit, XDA Trion maybe (no GPS, but 400 MHz, 3G etc)....but then, hey, HTC Trinity...Guys do you know, that you have probably the best phone ever made ? 3G, Video Calling, GPS, 400MHz (which can be overclocked - 500MHZ probably !), WiFi, great shape etc. 99% decided to get it with Orange now). Anyway just want to ask about some things...:
1. GPS. I'm using it a lot now (with my Mini S, external Bluetooth GPS). Found some threads about it, looks good, but if you can rate it - 1-10 please (does it loose the signal, reconnecting time etc, all together). And do you need to subscribe to any Orange GPRS packets etc. for using the GPS (like in Nokia N95, you need to pay £50/year to use build-in GPS) ? I'm gonna use different GPS software, not the one provided by Orange...
2. Battery drain. Practically. Cause I'v changed my Mini S ROM to a custom WM6 and the battery hold much, MUCH longer. Any problems with this phone ? Maybe not the phone, but software and how it handles the CPU and RAM usage (I'm gonna probably change the ROM to a custom WM6 anyway).
3. Are there any "-" of it, cause it looks great, as I said .
Thanks for any help.

that is..if you like slideout keyboards . otherwise the Trinity is one of the best devices produced by HTC (in my opinion).
Yes, I agree.... except for the lack of a macro function on its camera (à la HTC Prophet) the Trinity is a very competent all-rounder
After much searching since my First Trinity was run over by a car, I ordered one more - a white one. Nothing else has all of the features that are important to me. I actually hoped to find a new device that fit my needs but there is still nothing else!
Having said that, I was not happy with the black coating peeling TWICE. Sent it in for repair and it peeled again.
Ordered white. I have a black case to hide my shame.
It's the best looking HTC phone.
>>After much searching since my First Trinity was run over by a car, I ordered one more - a white one. Nothing else has all of the features that are important to me. I actually hoped to find a new device that fit my needs but there is still nothing else!
Where did you find a white one? Did it come with the GPS active?
Smart Mobile Gadgets got one (or more) in. Got it today. The white is pretty cool. I don't like it as much as my black one but it isn't an eyesore like I thought it might be.
It has a ROM dated in March 07. GPS active and Tom Tom CD in the box. I have 64 Mb free mem and it won't install. I'll figure that out later
Its the best PDA I've owned.
Looks good, nice size and most importantly works well.
Mine can be a littleslowwith some applications, but #I think the problem is due to the type of mini SD card I've installed my applications on.
The GPS function is great. Once you tweak it a bit, it will work as well as any of the stand alone devices.
Only downside is that HTC and the service providers are looking very reticent about issuing a Windows Mobile 6 Rom.
XDA Flame
If or when this comes out I think it could be a great handset ... apart from that I really like my M700, apart from the fiddling around to get Phonepad back, much better than my old M500
1. GPS works a dream. Was a bit worried about the Qualcomm chip - but despite it being apparently less sensitive than a SIRF III I get great results and have never had a problem. TTTF 2 mins maximum. You do not need subscriber services for GPS to work. although A-GPS is network dependent (quicker fix by downloading satellite info from your GSM provider). I recommend Tomtom - it's the best I've tried - and as long as you have 6.0.3 it recognizes the interal GPS as Internal GPS device instead of other NMEA device. 2.Battery drain not a problem - especially since the WM6 cooked ROMs for trinity have come out - a dream! 3. Only plusses for the Trinity. Especially if you get it from Orange (white) coz the only - about the Trinity is the paint peeling issue - which can be resolved like this: http://forum.xda-developers.com/showthread.php?t=307949. Go get yourself a Trinity today!
I still own a HTC Prophet and got a Treo 750v a few weeks ago.
The Prophet has a lot of things that I really like and the Trinity has the same specs, with a faster processor and GPS off course..
But what I like about the Treo is that it handles the phone functions superb! As well as ergonimics of the device.
The only thing I really miss is the options to tweak my device as much as you can with the Prophet/Trinity. I guess that this is caused by the facted that Palm is aiming at real business users and HTC is aiming at a more general market.
So if my Prophet died and I would have to buy a similar device I'd choose the Trinity without a doubt, but for now the Treo wins this match as far as I'm concerned
Thanks for your answers...anyway decided to get O2 XDA Orbit instead and wait for something with some more RAM . Gonna get it on Monday, play around....and who knows, maybe I'll switch back to Trinity.
Hi there please help me to decide wich Pocket PC to buy!
HTC P3600 or ASUS P735?
They are at approx. same prices so Wich one is better?
Thanks
Trinity. Why? Because P735 has no GPS, has a weaker battery, has no infrared. On the other hand, P735 is equipped with a faster processor, more flash memory, auto focus and probably doesn't peel off, which is nice...
@dubart
Thanks a lot, Dubart, I'll be more than interested if you could tell me about the p3600.
Actually how powerfull the battery is-especially when using wi-fi? The Samsung CPU- how fast is? is it capable of managing the latest version of Skype, or some 3D game? The camera isn't problem for me.
Do you know what graphic chip is being used in the Trinity? Is it capable of playing xvid without conversion?
Finally does every single p3600 peel off?
Camera is not worth mentioning at all... totally useless, if you want my opinion. Well, it's difficult to judge battery power because it depends on many many things (usage, network, etc) but I'll describe my experiences:
I usually charge my Trin every second night. Sometimes even every night, but I'm OK with that because prior to Trinity I used Symbian-powered Nokia N80 which never managed to last until 8 pm. Wi-Fi, backlight and GPS drain the battery significantly. I've tried 2-3 times using wi-fi & GPS all day long, and needed charging after a couple of hours already. Even bluetooth & infrared make an important difference when battery time is concerned. 400 MHz Samsung processor is fine, but only 64 MB of RAM is inadequate. Skype works just fine, but not v2.2 (good for chat only, voicecalls don't work) - you need to find v2.1 (both chat & voicecalls are OK).
Graphic chip is by ATI and I'm not sure about XviD...
And finally - peeling: mine started peeling off after almost two months, but a friend of mine has it (black one, too), and his one started after just a couple of days (maybe his fingernails are a bit longer ). It peels around reset button and around stylus 'compartment' (cannot remember the exact term for it right now...). You can read here that the problem exists with black ones only, but the white one is hard to find, unless Orange branded.
Networks here in Croatia are both 2G&3G and when I set the device to choose them automatically, it ocasionally drops calls (when on 3G), so I keep it manually on 2G and turn it to 3G just when I need to make a video call or surf using 3G speeds (which is not so often because of prices here...).
Where are you from?
polaris look sweet imho
If you are going to get any asus wait for the p750. It is going to be great. I have the 3600 and it has been a good little device. Its not the best at everything but it does everything well enough. I am going to wait for the p750 to come out in Oct/Nov.
I have the black p3600 for 3 months now and mine hasn't peeled at all yet! I have been really happy with it. Definitely worth the money. I use the wifi loads at home and it works a treat. (I am using it right now)
If that screen is 2.8", then it must be too big because it has a non-sliding keyboard
Buy the Trinity
Well I'm really concerned about the skype and that peel off.
Actually I've read that the skype for Samaung CPU is still in beta version.
Could be that the problem?
What kind is that chip by ati?
Imageon what?
Is it possible to use it for 3D accelerator?
Thanks to all of you!
Здравеи!
Don't worry about Skype. As I've told you - it works, but v2.1 which you can download from www.skype.com. Skype is probably working on a solution for Samsung processors. The graphic chip appears to be ATI The Imageon™ 2282 according to this thread: http://forum.xda-developers.com/showthread.php?p=1068170&highlight=ati+imageon#post1068170. Someone here posted a photo of Trinity's motherboard, try to find it, and you'll see what chip that is.
3D games work as well.
What's the price of P3600 in Bulgaria? Around 700€ here, that's why I bought it in Germany.
p3600
The best pda, smart phone i've ever had! Its got the best features about! It will do me fine until the polairs comes out

In BG now the trinity is sold for arround 500 euros, and I've heard that the cost will drop to 450 till christmas.
The graphics aren't teriblly fast but I hope to work for unconverted Xvid.
What about he Flash content viewing with the Trinity?
Is it true that there is fullyt functional plugin from Adobe wich makes possible viewing the flash objects inside the Pocket IE or Opera?
Have you tried this, and does the Trinity's hardware managed to render the flash content reasonably well-like desktop PC?
What about the sound quality from the stereo handsfree-bad, good, perfect?
I'm keeping asking a lot, please keep answering !!
I would wait for Polaris or maybe for Ipaq 600 / 900.

Yes, there is Adobe Flash available and it opens flash movies, but I just cannot make it work within IE or Opera. I always get a message that a plug-in is missing. The headphones that were in-the-box are nothing special, but I've found them to be OK after playing with Audio Booster.
Thanks Dubart!!

Yeap, it is. I bought one of those adapters from eBay. They're very cheap, altogether with shipping it costs around 6 €! The sound on Sony's megabass headphones is great.

Alright, if you're so smart, I'll give you one nobody answered to date, despite my questions in many threads:
What about a quickfix program that works for the GPS unit?
P.S. I don't really understand why nobody cares about this one, probably nobody had a SirfIII in their hand before with quick GPS running, so they can tell the difference with the P3600....
It's not that we don't care or haven't used other types of devices, i find that i get a lock within a minute or two max, by the time my GPRS or 3G connection is established & details updated i'd have a locked in GPS anyway.

Before my P3600 I had a Glofiish X.500. The quick fix took exactly 3 seconds, in the middle of Paris with tall buildings around me. In the same location, my P3600 doesn't even fix at all. I have to be out on an open square with lots of visibility to the sky, then it's 1-2 minutes.
Believe me, even though the P3600 is a lightyear advanced in terms of quality compared to the Glofiish, on the GPS side I find it extremely hard to accept even a 1 minute fix when I had 3 seconds before ! (and yes, 3 seconds, not 20 like on the P3300 which I also found slow for a Sirf III chip).
I guess that the new Glofiish X.800 is becoming a serious competitor here, with a Sirf III chip and 3 second quick fix as well.
Actually I also have an external Royaltek 2010. This one takes only 20 seconds for a cold fix, inside a car, without any quickfix software !
it isn't that bad actually. Under the same condition, it took my D810 around 2 mins to get a fix,the N95 about 4 and the 6110 Navigator,despite it being marketed as a GPS phone,7 mins.There are better GPS phones of course, but the trinity is not the worst so lets not dwell too much on it.

true, but when you're in a car, driving out of a parking lot, you don't want to wait for 1-3 minutes before getting a driving direction. 3 seconds only - that's what the Glofiish X500 needs, just as fast as a warm fix.
Googling and searching these forums doesn't bring up anything obvious. So does anyone know what chipset it uses? Looking at logged data it is operating at 1Hz.
It's built-in the Qualcomm Snapdragon chipset, see here
Thanks. I'm just trying to work out if it will do as good a job as my external bluetooth sirf III one I used for racetrack lap timing with my previous phone.
For normal navigation the inbuilt GPS gets fast lock and seems to work okay but the more accuracy the better for the track.
Guess I can just run it and compare times to the electronic timing (which take 1-2 hours to be printed out and released hence the need for an instant solution).
it's the best inbuilt gps ive used gets a lock in under 10 sec my xperia used to take 30s to 1 min.

The SiRF chip is better than the GpsOne on Qualcomm SOCs.
And to above post, this might be because AGPS is actually working on this phone rather than the antenna being better.
dont think i have agps enabled if im correct it uses data, when i start igo 8 no connection is made, im just using antena.
my device recives signals even if iam in home and recives at least 3 satellites

it will be down to how fast/often the app polls the gps surely?
I've been playing with it a fair bit (for the same purpose) and it certainly better than one or two stand alone gps
Getting satellites indoors or getting a fast satallite fix does NOT automatically indicate that the GPS chip is good.
Actually GPS on the HD2 is pretty poor compared to the SIRF III chip, or even compared to other HTC devices, I am talking about accuracy and stuff. This is a fact, so i don't want to hear any more about "how good it is because it gets a fast fix" or other crap
For more info:
GPS going crazy (proven with plot screenshots)
Weird GPS problem. Moving even while my car is motionless.
Recent ROM/Radio for the HD2 upgrades do seem to improve this bad GPS functionality though.

Accurate, scientific data to prove that assumption, please?

I understand your viewpoint, actually I had such information (plots of the HD2 and of other devices), but I really can't be bothered to make them again and spend all the effort on it... just believe me when i say it (or don't believe it, i'm just sharing what i know)... or have a read through the topics i linked to (should be enough proof in there)
Well if I have time I'll try both at the same time this weekend at the track (still have my old phone and external GPS).
With the high speeds involved and a racing line that varies no more than 1-2m it becomes pretty easy to tell if the GPS is out when plotted on a track overlay.
Plus values for lat/long g forces and speed are all extrapolated so if these are out it becomes pretty obvious.
