This is more of an informative/warning post to those who are considering purchasing the Garmin Mobile 20 GPS unit.
I've been a big Garmin fan since I owned an iQue3600, which was a Palm PDA that contained a GPS antenna and software. It worked quite well, but I recently migrated to a Cingular 8525 to get the convergence device.
The Mobile 20, unfortunately, suffers from the problems described in this thread:
http://forum.xda-developers.com/showthread.php?t=277742&page=1
Essentially, the Mobile 20 advertises the fact that it can charge your cell phone while using the GPS function, using it's passthrough cable. While I know that it will charge with a T-Mobile SDA (a Windows Smartphone), it does not charge the TyTN/Hermes, even though the Cingular 8525 is listed as a compatible phone. (Note that the GPS software does run on a TyTN, and runs well.)
The trick of connecting pins 4 and 5 on the mini-USB end of the cable does not work, I tried that today. So, sadly, the only solution at the moment is to not use the Mobile 20 to charge the phone, but use a second charger.
I am hoping that Garmin can fix this issue, but I am not holding my breath. In the meantime, I am content enough to use a secondary car charger.

Hi, this is my first post to these forums, although I did spend a couple of hours browsing after finding them last night.
Having played with my wife's month old Mio168/TomTom5 and loved it, I decided that when my CPW/o2 contract was up I'd go for a pda/phone rather than the SE K750i I had previously been planning on.
I did just a little research and went for the XDAIIi over the MDAIII (don't like T-Mobile's pricing!) and XDAIIs (no wi-fi, slower and unnecessary keyboard).
I initially thought I had a great unit but things haven't been as smooth as I expected.
http://www.globalpositioningsystems.co.uk supplied me with a Holux combined GPS receiver/cradle, Kingston 512MB SD card and screen protector at very reasonable prices and with swift delivery.
First thing I noticed was that whenever the phone utility was brought on-screen, it showed me that my last caller was the very first person I had phoned on it. After any call, the same info would pop back to the display, too.
Another little thing that surprised me was the SIM code entry. I have set an 8 digit code. When I enter the first number it appears on the display as an asterisk but when I hit the second, the first two numbers appear (the asterisk changes to the digit). Is this normal or a quirk of having '08' as the first two digits of my code?
TomTom5 installed fine but kept randomly freezing (whenever a call or txt msg came in it was certain to happen) so I contacted o2 Customer Support who told me to take it back to be checked out.
Three days after installing the card (and before I had taken the unit for its o2 'inspection') the SD card suddenly 'disappeared'. Actually, it's shot; it isn't recognised by my XDAIIi, my work supervisor's XDAIIi, my wife's Mio168 or my computer's USB card reader. I researched this a little and found it a fairly common occurence but the only recommendation seems to be to format it. HELLO? How does one format something that no equipment recognises? Fools!
Actually, while googling the SD card problem I found people recommending the removal of o2 Active to cure TomTom lockups. o2 Tech-Supp were very helpful with this - instructing me how to hard reset and install 'corporate' using the 0506 password. This appears to have cured almost all TomTom problems although I need more than the old 128MB MM card I currently have for storage!
This also fixed the 'last call' bug I'd been experiencing.
Having found this marvellous forum, I set about finding info for the XDAIIi and promptly discovered that the wikki bears little specifically for it. I would update it but don't know enough yet!
I did read a post last night that pointed out to a user that the cradle charges the battery from just the USB port, and not requiring the AC supply so I decided to check it out. Sure enough, the battery is shown as 'charging' but after leaving it overnight, I find that the charge has actually dropped to 87% (still says 'charging', too) from the 95% I left it on.
Perhaps I have a faulty cradle.
It also seems a little odd to me that I can use mp3s for ringtones but can only use wav files for the alarm!
Is there a way to stop the wi-fi 'do you want to connect' popup appearing when TomTom is running other than disabling wi-fi before running it? It's a right pain having TT freeze until I get rid ot the popup.
One other little thing - anyone know how I can ensure that GPRS isn't going to be used for web surfing? I don't want it to be activated accidentally and certainly don't want to go surfing on it for an hour thinking I'm using wi-fi!
Don't get me wrong - overall I'm still happy with the XDAIIi (look -> ) but there's just a few doubts as to whether I went the right way creeping in.
Hi there, im pretty much a "new" user of the XDA 2i aswell but have learnt alot from using this forum.
I have almost the same setup as you now as far as the "corporate" install, TomTom5 etc etc .... but i have updated the ROM on mine to the latest Imate version, which you can find in one of these forums , its called PDA 2K ROM streight from I-MATE or something along them lines.
I would recommend that you update also as it fixed a few problems was having with lockups, but make sure to do alot of research before you attempt it cos you dont want to knacker it up
Anyway .... my cradle charges fine just using the USB (no AC adapter)
Passord thing .... this has came up before , it for some reason displays the digits when the numbers 08 are first , i seem to remember it being something to do with emergancy calling features, although i didnt think that they started with "08" but there ya go
GPRS ... will only activate when you cannot get a Wireless signal, the hirachy is WiFi then GPRS, but to be on the safe side i removed all the setting configurations for the GPRS so it can never connect, i never use it anyway.
Im not sure about the "Do you want to connect" popup you get when running TomTom as it doesnt happen to me , perhaps you have wireless enabled all the time, id tun it off to save your batteries anyway.
well .... i think ive covered a few of the things your asking as good as i can, best of luck with it
Thanks for the reply, Danny.
I haven't had any TomTom problems since 'going corporate' so I'll wait and see how it goes before trying another ROM - taking warranty into consideration too.
Mind you, I haven't received any calls or texts while running TT either so all may not be as it seems.
Hmm. I'm plugged into a 4-port USB hub that came with an external power supply I don't use, so I wonder if that makes a difference. I'll have to pull out the base unit and plug the cradle in there to check charging on that.
I've double checked that I have no settings for GPRS so unless o2 'push' them to me I should be OK.
Yes, I do have wi-fi on all the time and the battery still lasts all the work day with a little usage when time permits. My cradle/GPS receiver charges the pda when it's in there on the way to/from work, so I don't really have to worry about that.
I'd just like to not be bothered by the connection dialogue box rather than have to turn off wi-fi for navigation purposes... have you seen how many networks are open out there? Not just the city centre ones, there are loads of not-very-secure company and household networks that can be connected to and utilised. Free broadband internet - almost makes you want to get a laptop!
the computer to which the cradle is connected via USB must be turned ON, or else there will be no current passing through the cable. Thus, no charging the PDA. The Ipods have the same "handycap". You can always use the AC power adapter...

Quite true, but my charging test was performed while the computer was on and defragmenting my 5 partitions.
Actually, my Soltek motherboard has 'hot' USB ports at the rear that still supply a little 'juice' when the power is off - my USB hub, BT dongle and Intellimouse 4 stay alight when the main machine is off, although I've not bothered to check exactly how much voltage is supplied.
Hi all, after months of try&error and buying 2 (TWO!) MDAs (Wizard & Charmer) i finally found out WHY sometimes GPRS data flow stops and no incoming calls will be put throught (they land on mailbox):
It's the docking stations! Just let me explain that a little bit more: Both Wizard & Charmer will be delivered without any docking stations, so I bought two different on Ebay + one active holder from Brodit for my car.
After I put Wizard or Charmer in one of the docking station it's necessary to call 2 or 3 times until the call gets through, also in the car (Brodit), and - GPRS data flow, that means even I'm connected (2 GPRS arrows are there), stops after 2 or 3 minutes. I see that with a network monitor called Phatnet (very recommended!)
So now comes the real scurillic thing: If I use the original AC adapter from T-Mobile nothing of the above happens... GPRS data packets flow hours and hours without any breaks, and calls come through.
The docking station definitly loads the devices, but it takes longer. So here's my conclusion: The AC Adapters and the car adapter give to little current for the radio part in the devices - sounds strange, but I have no other ideas.
So now what? Try yourself please, anyone who owns Wizard or Charmer and some other AC adapters than the originals should tell here - it's easy, just put the devices in, surf a little bit for just a couple of minutes and you'll see surfing stops. It's not dependend of the loading status (orange or green led).
I tried different Rom updates, different devices and now it seems that power is the reason, really annoying. Tell us your experience!
Yours B.
Here are the links of the 2 docking stations:

Must be a Charmer/Wizard flaw as my Magician doesn't act at all like this.
What I really don't understand is how you can even make a phonecall or use gprs when there's no original AC-adapter connected to your device, when a car charger doesn't give you enough current to have the radio operating as it should be. So your devices must be pretty crap then lol.
I think the cradle's are somehow interfering with the radio. The current can't be the main issue, otherwise the device wouldn't be functioning on a battery only. Guess it comes in a strange state, I noticed that my magician doesn't hold a gprs connection while Act.Sync is running, maybe this is something simular.
But it sure must be a pain in the rear bottom I agree to that.

Well there's some additional information I researched:
When connecting the device to the original AC adaptor it does NOT switch on the display, when connecting to the cradle it does. So the pinout of the connector must be different and Wizard/Charmer maybe (half way) believes that it has been connected to USB of a PC, but not in a defined state. Remember that my docking station IS NOT connected to a PC, it's only there for power.
Somebody maybe knows the pinout of the delivered USB sync cable and the AC adaptor?

Hi
Using T-Mobile (UK) on the Stirling/Bannockburn transmitter...
Just changed to a Hermes from a Universal because I bought a umpc and no longer needed somet the size of the universal.
On the universal, I was seeing downloads of around 300Kbit/sec and uploads of about 100Kbit
On the Hermes with HSDPA enabled (I assume) I get downloads of between 700 and 1000Kbit/sec with uploads at 300Kbit/sec
Both the above measured with http://www.dslreports.com/mspeed/jisok=1
Pleased --> Yes indeed I am - a worthwhile speed increase
But
When I connect to the hermes via bluetooth from a laptop (using hermes as a modem), I am only seeing 300Kbit (both upstream and downstream). Both devices have bluetooth 2.0 (EDR).
On the universal I used to see the same speeds over bluetooth as on the device its-self (although I realise that my laptop speeds with the hermes exceed my universal speeds!)
Does HSDPA only work when the connection comes from the device its-self (rather than via bluetooth)??
Is there some kind of issue with bluetooth that slows things down? would USB prove to be faster?
The laptop has the option of fitting an HSDPA module, but I never went for this because it would also have meant paying for two contracts!
On the whole, I like the form factor of the hermes and dont really miss the keyboard/screen of the universal esp now I have a umpc.
Only critisism of the hermes would be that its not exactly production quality. Compared to my universal its very buggy. Guess thats just the products immaturity - its certaining no more buggy than my universal was on day 1.
Maybe HTC will eventually replace the universal - I got fed up with waiting and my old contract ended. The chap in the t-mobile shop showed me pics of t-mobiles forthcoming take on the HTC athena (think thats what its called - the one with the detatchable keyboard... but that's hardly a replacement for the universal.
Anyone had any experiences with using hermes on t-mobile (UK) over bluetooth as a modem from a laptop, please reply!

i cant get over 350k using bluetooth to desktop either.
Tytn has bluetooth 2.0,but NO EDR, maybe that is y.
when i use USB to desktop, i can get around 550k.
Hi
Looking at the modems for both USB and Bluetooth, the baud rate appears to be 115,200. In ControlPanel-->Modems.
This is the baud-rate limit for the hardware
If you get up the properties for your dialup account, and look at the modem properties from there, then you can select ~900Kbit. Unfortunately this does not alter the hardware port restrictions.
Of course, the speeds we are seeing are better than is poss over 115,200 anyway...
I find the USB modem thing very hit and miss - it only works properly where there are no other modems present otherwise, if the dial-up account cannot find the usb com port it just changes it to something else.
Other problems I have with the hermes are that sometimes it refuses to connect from the laptop at all (requiring a soft reset). Hopefully a new rom will fix this - this problem did not exist on my trusty universal.

I upgraded my phone and I am selling my unlocked Wizard loaded with Faria's Crossbow Mobile 6. It was originally with Tmobile USA. It comes with a 1GB microSD memory card, original battery, extended battery (2 times the charge), case, USB connect cable, wall charging unit, and Holux GPSlim 236 GPS. All for $275.00.
Phone works very well, especially with the extended battery which I charge every 2 days. Condition of the phone is good with minor nicks and the screen in very good condition.
Email me if you are interested at [email protected]
Shipping is $20.00 in US.
Thanks,
Mike
how did you get crossbow mobile 6?
email me at [email protected]
Can we place ads on this site? If yes, I have an MDA Unlocked and will load any ROM and provide a lot of installed and registered applications such as SPB PocketPlus, FInance, Diary, Backup, etc.
If interested email me.
Hi Mike. How about $150?

I have a (dis)connection problem with my XDAIIi which only started about three weeks ago.
It may (or may not) be related to a problem that I had when I was using my XDAIIi in the car as a sat nav.
As is my custom, I tucked the XDA into the glove compartment (with car charger attached) when I popped into a shop. When I got back in the car, the XDA was part of the way through a hard reboot and the car charger was not working. Since about that time, it has only been possible to connect to the device (via the USB port) occasionally. (I have never had any success with IR, Wireless or Bluetooth – but have never really tried before.)
My company laptop has slightly more success at connecting to the XDA than my personal laptop has – both of which worked perfectly before. I have a USB sync cable as well as the standard cradle but there is no difference in the connection performance. I have tried loading various versions of Activesync but without any success. The problem is basically as follows:
Mostly, when I attach the device to either laptop, it will connect normally (if a bit slow) and get part way through the synchronisation process before disconnecting. Typically, the connection lasts less than a minute but it can be for quite a long time – e.g. long enough to load TomTom Navigator 5. Rarely does the connection last more than a few minutes though and never more than about 10 minutes.
My company laptop has a firewall as does my personal one – but they are different. I have disabled my personal laptop (Windows) firewall as well as the virus scanner etc. but it has no effect. I have tried hard reboots several times but am reluctant to do any more as loading software back again is a painful (hit and miss) process. My personal laptop has various anti-spyware packages which I run regularly as well as CCleaner. My company laptop has none of these though.
If anyone has any ideas what is wrong or (preferably) what I might do, I would be extremely grateful. My personal hunch is that I may have caused some damage to the device when I put it into the glove compartment. Maybe the charger cable was a bit tight and it damaged the connector. Or the car charger may have produced a voltage/current spike somehow and I have damaged some internal circuitry. (Quite why the XDA connects at all though is a bit of a mystery.)
PS I don’t want to buy a brand new TyTN2 (much!) but if I have to …… Oh well!
