How do i correct the time on my TOmTom one.

One of 2 things happened here. Either your T-con board is defective and needs changed, or your Panel is defective and you need a new TV.

According to the manual:

The easiest way to set the time is by tapping the Sync button. Your ONE XL will then take the time from the GPS information it receives.

Hope this is helpful.

I would recommend contacting Tomtom support directly about this, thay are very good.

There ar frequent minor map corrections accessible through MapShare. You configure your GPS to accept these corrections. You can selected to accept ALL, or from TRUSTED sources, or ONLY corrections verified by TomTom.
Connect the unit to the computer and download the MapShare corrections. If your map is too old, maybe it is time to get the latest one.

If you have started using your unit not long ago (less than 30 days) you may have the right to a free update. TomTom offers the 30 day latest map guarantee.

Connect the unit to a computer where you installed the tomtom HOME application. Upon registration, HOME will proceed to update your GPS.

certain map share corrections can only be reported...some of those corrections are missing streets...please be advised that the maps on your unit are preloaded...the ability to change them is not possible....the errors can only be reported, and then will be added on future map releases..check out the support page for more on map share

Go to My Computer, then the TomTom drive and click explore. Move your Map folder to the desktop. Then, delete everything on the tomtom drive. Unplug it, plug it back in, and start up Tomtom HOME and install all updates, keep unplugging, plugging back in, and installing updates until there aren't any more updates. Then move your map folder back to where it was on your TomTom drive.

Please rate, Thank you!

TomTom Home now has a fix which corrects the stuttering problems with the computer voice needed for the 'text to speech' function on the GO720. Simply plug your device into your computer and have it connect with your computer. You should automatically see a large fix available which will correct the problem. Download it as I did, and the problem is corrected.
