Re: Garmin gps, novi
What do you see if you use it in the open air? Same thing?
Some cars have a metal coating on the windows that works as a sun block, usually french cars. In these cars satellite reception is poor and this can be a reason for bad reception. Sometimes these problems also occur when a cell phone is too close to the gps. The gps does need line of sight to the sky to get a good signal, usually stuck to the windshield is sufficient.

With a normal GPS device, when you first switch it on, it needs some time to locate enough satelites. Most of the time it needs at least 5 satelites. Some time should be like minutes and not hours. After the GPS device fond enough satelites, it knows where it is and can when it is switched on again work faster. When you try to let the GPS search for satelites indoors, or without a free view to the sky, it is possible the receiver never can find satelites at all. I don't know if any test of the Lowrance iFINDER Hunt GPS was placed on the net, but that is where you can check how long it should take for the GPS to find enough satelites.
A TomTom GPS Devices requires a minimum of at 4 satellites in order to triangulate your position. Losing signal can be caused by many different factors such as your in an area with tall buildings or trees, unable to connect to at least 4 satellites, or possibly that the device hasn't been used in a long time. Besides simply exchanging it to resolve the issue TomTom has a feature called QuickGPSFix which determines where the GPS satellites will be located for the next 7 days. This feature is not yet available for MyTomTom but it will either be added by the On Device automatic updates when it is available or for advanced users you can use a Bluetooth connection with a compatible mobile phone.
On your TomTom Device go to TomTomServices > Tap Download QuickGPSFix. Almost any phone is compatible especially newer SmartPhones. Hopefully this helps you resolve your issue.
Hello jacke328, In order to maintain satellite connection your GPS receiver needs a clear view of the sky. If you are operating the GPS in areas where the view of the sky is limited due to tall buildings, hills and mountains, or dense forest, your GPS is liable to lose signal from one or more satellites and this can impact the receiver's ability to determine your current location. If you are operating the GPS inside your vehicle an external antenna may help significantly. The body of the vehicle can act as a shield, blocking the GPS's ability to receive satellite signals. This is why most manufacturers recommend installing GPS receivers on the dashboard with a clear view of the windshield as this maximizes the amount of visible sky. Installing an external antenna on the vehicle and connecting this to the GPS can help significantly, however. Depending on the geography of where you are operating the GPS, you may have to live with an occasional loss of connectivity.With proper mounting you can minimize this, however.
I have a 276C that has the same problem. Garmin has a unit with this
problem and is working on a solution. The problem is that the real time
clock loses time when the unit is turned off and disconnected from a
power source. As a result when you turn on the unit it thinks the
satelites are in a different orbit than where they actually are. The
unit will continue trying to aquire forever and not find the satelites.
You have to select "New Location" from the menu and select "Autolocate"
and the unit will start to look for any satelites in view. The unit
should get a fix within 15 minutes. This is a very frustrating problem
having to reset it every day. There is a new version of firmware (5.3).
I don't know if the problem has been fixed with this release.
10-15 minutes is normal. Did you take it outside? GPS doesn't work indoors. Try in an open field, no trees. Should lock in a few minutes. I always do the following: i key in the destination address at home, then put it under 'favourites". When i start driving, i put the unit in my car and look up the recently added favourite. The unit then has enough time to lock on to the satellites.
