where to download TOM TOM for X1 - XPERIA X1 Themes and Apps

HI guys, wherre can i down load TOM TOM for X1?
is it "turn by turn" navigation? is that what A-GPS means?

Assisted GPS, generally abbreviated as A-GPS, is a system which can improve the startup performance of a GPS satellite-based positioning system. It is used extensively with GPS-capable cellular phones as its development was accelerated by the U.S. FCC's 911 mandate making the location of a cell phone available to emergency call dispatchers.[1]
[edit]
Description
GPS operation uses radio signals from satellites. In very poor signal conditions, for example in a city, these signals may suffer multipath where signals bounce confusingly off buildings, or be weakened by passing through walls or tree cover. When first turned on in these conditions, some non-assisted GPS navigation devices may not be able to work out a position due to the fragmentary signal, rendering them unable to function until a clear signal can be received continuously for up to 40 seconds (the time needed to download the GPS ephemeris).
An Assisted GPS system can address these problems by using data available from a network.
Assistance falls into two categories:
Using information known to the assistance server but not the GPS receiver
It can supply orbital data or almanac for the GPS satellites to the GPS receiver, enabling the GPS receiver to lock to the satellites more rapidly in some cases.
The network can provide precise time.
The device captures a snapshot of the GPS signal, with approximate time, for the server to later process into a position.
Accurate, surveyed coordinates for the cell site towers allow better knowledge of local ionospheric conditions and other conditions affecting the GPS signal than the GPS receiver alone, enabling more precise calculation of position. (See also Wide Area Augmentation System and CellHunter.)
Calculation of position by the server using information from the GPS receiver
The assistance server has a good satellite signal, and plentiful computation power, so it can compare fragmentary signals relayed to it by GPS receivers, with the satellite signal it receives directly, and then inform the GPS receiver or emergency services of the GPS receiver's position.
As an additional benefit, in some A-GPS device implementations, the amount of CPU and programming required for a GPS receiver is reduced by offloading most of the work onto the assistance server. For modern hardware this is not a major consideration but many 20th century GPS navigation devices used Intel 80386-class 16 MHz CPUs[citation needed] or similar hardware.
A typical A-GPS-enabled receiver will use a data connection (Internet or other) to contact the assistance server for A-GPS information. Some A-GPS devices cannot fall back to standard GPS, needing cell tower or internet signal as these A-GPS devices won't function with only GPS satellite signal.
Many mobile phones combine A-GPS and other location services including Wi-Fi Positioning System and cell-site triangulation in a hybrid positioning system.[2]
High Sensitivity GPS is an allied technology that addresses some of these issues in a way that does not require additional infrastructure. However, unlike some forms of A-GPS, high-sensitivity GPS cannot provide a fix instantaneously when the GPS receiver has been off for some time.

XDAIIs wifi problems

I just bough my XDAIIs. Live in Sydney Australia.
I'm generally happy with it but the wifi reception is really bad.
I work at a Uni where we have a huge wireless Network with over 150 basestations and I work in the ITS department where we have at least 4 wireless access points. 3 of them a A radio and one is the BG radio.
From what I've seen the XDAIIs used the BG radio and not the A but I have been reasing several posts and it looks like the wifi antenna is very weak.
I too took my XDAIIs right in front of the base station set the reception to FULL and could barely manage a signal and even when it did manage a signal I couldn't connect.
I have
ROM Version 1.12.62
ROM Date 10/04/04
Radio Version: 1.02.00
Protocol: 1337.32
ExtROM Version: 1.12.925WWE
Is it possible to update the ROM on the XDAIIs yet with a later version such as ROM 2.02.t1WWE. I see posts inidcating its possible on XDAII but not XDAIIs

Peter,
I haven't bought a Blue Angel yet, primarily for this reason. However, I've been watching these forums closely to see if anyone knows what the problem is with WiFi reception.
So far, no one has posted a solution, and I fear it's not a ROM or software related issue, but a hardware design issue. My guess is that the WiFi antenna design is extremely poor and either:
1. Internals are interfering with the reception of the WiFi signal
2. The case (which I do believe is some metal alloy) might actually be preventing the internal antenna from receiving external signals.
Hope it helps. By the way, the Blue Angel only supports 802.11b, not 11g or 11a.
Some wireless defination
802.11a - almost proprietary wireless network (All PDA based devices are 802.11b, as per other reply)
802.11b - standard 11mb, and what has been mainstay of most wireless devices up until past 6 months
802.11g - standard 54mb wireless.
Sure there are some others in the range afterwards, but next comes configuration.
Most A wireless networks only communicate with other A networks, few were bought out with interopaeratibilty.
B networks will communicate with B Networks
Most G networks are set by default as communicate with G only (The fast setting), and are not changed to support both, as with many wireless networks, slows the entire speed to the lowest connected speed.
Nearly all G wireless networks are backward compatible with B networks and hence why is displayed on box B/G
Hope this clears it up.
For some real run, get wififofum and a bluetooth GPS, and plot out the access points, then hand to your security audit guy, watch those eyes turn red.
I'm not sure it is a hardware issue because mine works absolutely fine and I've spoken to others who have no problems. Anywhere in the house I get a really good signal (about two thirds on the signal quality indicator) and even outside I get a signal. And that is on best battery setting. A friend of mine lives three doors down (i.e. a lot of bricks in the way!) and I JUST get a signal in his house with best wi-fi performance set.
This would suggest the hardware is fine. Certainly it is on a par with my Dell 510m laptop with a centrino chip.
The only thing I've noticed is that the signal indicator drops off VERY quickly as I move away from the house. So it will stay on two thirds for quite some time and then suddenly drop down to almost nothing about 30 meters away.

WiFi fine on Cingular Siemens Sx66
Following these posts led me to have low expectation of the WiFi capability of the SX66, but having received mine on Monday, I am pleased to state, that at least on my unit, the WiFi is working great. On my AP, I run MAC filtering, 128bit WEP and shared authentication. To ease the installation, I turned my AP back to OPEN Authentication, WEP OFF, and MAC filtering OFF. In this config, the SX66 immediately found and connected to my AP. This also gave me an easy way to determine the MAC address of the SX66 for inclusion in my AP and my router tables (ie PPC Wireless LAN Manager MAIN tab). The WiFi signal strength indicated was on par with what my two other WiFi notebooks indicated(ie around 3/4 max). Taking this one step at a time, I then added the SX66's MAC address to my AP and router tables and turned on MAC filtering. That worked okay, so I then set the AP to WEP encryption and entered my 128 HEX (yes HEX) WEP key into the SX66. BINGO, that worked as well. Then I set the AP and the SX66 into Shared Authentication mode and that worked as well. So, I have my SX66 connected my well guarded WiFi AP with full filtering, encryption and authentication active.
As I mentioned, in testing the WiFi capability, I am finding it at least as good as what my Dlink DWL650+ PCCards running in my notebooks and it also seems to have similar range.
I did note that if you leave the Power Save Mode in the default setting ("Best Battery"),it really dogs down the perfomance of WiFi. I moved mine back to "Best Performance" and the web browsing speed is on par with my notebooks.
All in all, I am very pleased with the WiFi connectivity.

wi fi reception
Hi, I don't know about wi fi and all, but could it be an issue where there just isn't a good signal..or the signal you receive depends on where you are as it does if you have a tower close by or not? Sorry if I seem like I don't know what I'm talking about...because I don't. I've just been getting into these devices in the last 6 months and really behind...I'm wanting a blue angel (early next year), but want to make sure it's right for me and weigh the good against the bad

GPS no radio no wifi working?

Hi all
I plan to use the Galaxy Nexus as a music player. I will not activate it with a phone company. Therefore I will not have any voice or data connection. Also, I won't always have a wifi connection.
I would like to know if the GPS will be working under these conditions.
Definition of working : will give me a coordinate of longitude and latitude. Separate programs may require data connection but this is another issue. Might just download offline mays.
Thanks.
Yes, it does work.
Download GPS test from the market.

GPS not working (also can't capture NMEA)

Hello,
I've new LS970(Sprint) flashed to E975 rom. And I have GPS problem: I can't see any sattelites and NMEA stream, tried several programs. I had same problem with LS970 rom. Should NMEA be active during no GPS signal? Maybe it could be possible to access serial tty where GPS is connected to send it some debug commands? What device in /dev/ is GPS? I don't know if you understand my me
Some time it gets location with accuracy of 20m, but only when connected to wifi internet, but still no sattelites in list.
I am in Europe.
Thank you,
Kęstutis

problem with gps antenna

i have a problem with navigation gps on my huawei rio-l01, the gps antenna doesnt work, it lose signal continously or it is very inaccurate.
i try to reset to factory options in recovery, or different option as: only gps, gps and mobile connection
i think it is an harware problem but I cannot find the spare part on internet
