GPS reception

When you first start your TomTom XL navigation device, the device may need a few minutes to determine your GPS position and show your current position on the map. In the future, your position will be found much faster, usually within a few seconds. To ensure good GPS reception, you should use your device outdoors. Large objects such as tall buildings can sometimes interfere with reception.

12. TomTom Map Share

TomTo m Map Share
With TomTom Map Share, you can correct errors on your map and share those corrections with other people in the TomTom Map Share community, as well as receiving corrections made by others. If you find a street that has recently been blocked to traffic which was open before, you can use Map Share to correct your map and then share the correction with other Map Share users. You can use Map Share to send and receive map corrections during the first year after the maps release date. This means that one year after the release date, you will no longer be able to send or receive map corrections for that version of the map. You will still be able to make corrections to your own map for use on your own device. Note: TomTom Map Share is not available in all regions. For more information, go to tomtom.com/mapshare.

There are two types of map corrections: Corrections that are immediately shown on the map. These include, changing the traffic flow of a street, blocking or renaming a street and adding or editing POIs. This type of change is immediately shown on your own map. Corrections that are reported to TomTom but not shown immediately on your map. These include, missing streets, errors in highway entrances and exits and missing rotaries. This type of correction is investigated by TomTom and, once verified, is included in the next map release. These corrections are therefore not shared with the Map Share community.

Making a map correction

Important: For safety reasons, you should only mark a location when you are driving. Do not enter the full details of an error while you are driving. 1. Tap options in the Main Menu then tap Map corrections. 2. Tap Correct a map error.

Walterova (aInstitute of Medical Chemistry and Biochemistry, Faculty of Medicine, Palack University, Olomouc, b Laboratory of Biotransformations, Institute of Microbiology, Academy of Scienes of the Czech Republic, Prague): Natural Substances in the Prevention of Gastrointestinal Diseases Some polyphenols such as lignans, flavonoids, and flavonolignans, phytosterols, and non-digestible oligo- and polysaccharides were shown to have in vitro and in vivo chemopreventive and other positive physiological effects on the epithelium and metabolic processes in the gastrointestinal tract (GIT) of humans. Most of these substances are metabolized in the colon; some of them stimulate bifidogenic bacteria and Lactobacilli. It was proved that sufficient daily intake of these phytochemicals shows beneficial effects on cancerogenesis in stomach and colon. Functional foods and dietary supplements that contain these substances may play an important role at present when the incidence of cancer diseases of GIT increases.
