Re: Can't get satellite signal for my GPS.
Finding a GPS signal In the following cases it can take up to 5 minutes to find your current position:
You use your TomTom device for the first time.
You haven't used your TomTom device for a longer time.
Your TomTom device has been relocated without using it (e.g. after travelling by plane or train).
If it takes longer than 5 minutes, make sure that you are in an open place without tall buildings or trees around you. Once your TomTom device has located your current position, theDriving View is shown in full colour and shows your position on the map. Tip: Most TomTom devices can use QuickGPSfix™ to locate your current position faster.

Usually, when it's waiting to get a valid GPS signal, it is "listening" (scanning) for satellite signals to establish your current location. If you are in the open outdoors, i.e. not inside a building or under extended covers, it should get the satellite signals within a minute or so.
1) Make sure the TomTom can "see" the sky well... the GPS satellite waves are rather weak and easily blocked by trees, and anything not a window.
2) Hook up your TomTom to the computer (see details at www.tomtom.com or in the manual)
2b) Do a "sync" and download all updates. One of the updates is a small file that tells the TomTom where the satellites are located this week, and helps it sync up much faster. The longer time between uses, the longer it takes TomTom to find the satellites, and that can takes up to 2-5 minutes sometimes.
That can be frustrating with a car full of people waiting to get going and the driver doesn't want to drive without making sure the TomTom works and is giving valid directions.
check the port is set to 8 not sure if your model has GPS search wher it finds the port and vbaude automativcally, if it does use it and see if that fixes it if not your battery is too low you have a damaged SIIRF chip and that is expensive to repair
Try resetting your device. Depending on the model you have, this is done by either using the pin or holding down the power button for about 15 - 30 seconds. You'll know the reset has been successful when the legal agreement come up when it comes back on. Once this is done, go outside and on the device, go to the satellite detail screen and wait until several (about 4) of the bars are 75% or higher (they should change colors). You should go the the regular screen after that and you should be able to navigate again.
Tom Tom needs comms with GPS satellites orbiting the earth.
Make sure you are outside your home so the GPS can find these signals. Initially it may take up to 5 minutes to make these connections. One the satnav knows where it is, all subsequent connections will be a lot quicker. :)
Some vehicles have windscreens with special coatings which prevent the satnav initialising with GPS satellites. If this is your problem, the only solution is to purchase an external antennae for your satnav. :(
Make sure you are outdoors. Some buildings are well shielded due to their construction.
If you are not downloading the GPS Quickfix every week then it will take much longer for the unit to acquire satellites. Perhaps as much as five minutes.
If you are outside set in a destination and if you have not got satellites within a few minutes then drive a a few tens of yards and it should suddenly find satellites. Happens to my unit as well. HTH Peter
