Your navigation device uses the signals of at least 4 satellites to get a GPS fix and determine your starting location. This can take longer when the GPS signal is weak or partially blocked.
When using QuickGPSfix, a feature only available to TomTom customers, your navigation device retains information about where the GPS satellites will be for the next 7 days. Your navigation device can then calculate where you are very quickly and with only a weak GPS signal.
If your navigation device is unable to receive a GPS signal, see No GPS signal on your navigation device? Here's what to do
Updating QuickGPSfix
The process of updating QuickGPSfix depends on the type of navigation device you have. When a new QuickGPSfix file is available you will see it in your list of updates. For more information, see: Updating your navigation device
Note: If you have a connected device that receives TomTom Services through your Smartphone or a built-in SIM card, you receive automatic updates for QuickGPSfix as soon as they are available. For Smartphone Connected devices you need to connect to a compatible Smartphone in order to receive updates.
