I think its quite important that all users of LIVE devices (Sim card embedded) can read it here. It states:
"Only if you give us your permission, your navigation device will continously collect information and send it to TomTom at regular intervals. The information is also stored on your device until you connect it to your PC, then the information is sent to TomTom and deleted from your device. The information includes details that identify the navigation device, your MyTomTom account name and information entered while you were using the navigation device.
TomTom uses this information to be able to deliver LIVE services to you and to improve the HD Traffic service.
Within 20 minutes of switching off your navigation system, TomTom automatically and irreversibly destroys any data that allows identification of you or your device. This, now anonymous, information is used to improve TomTom's products and services, such as maps, reports on Points of Interest and average speeds driven. These products and services are also used by government agencies and businesses.
Using your navigation system, you can join the Mapshare Community or report speed cameras. If you choose to use either of these services, your reports, that include location information, are sent to TomTom and kept together with your MyTomTom account. TomTom then uses your information to improve its maps and speed cameras.
If you no longer allow sharing of information, none of the above information is sent to TomTom and information previously stored on your device is deleted. You won't be able to recieve HD Traffic or mobile speed camera locations, or use any other LIVE services.
TomTom will not give anyone else access to the information collected from your navigation system.
In choosing to provide TomTom with information, you are helping to make driving better, specifically by improving maps, traffic flows and reducing congestion. We appreciate your help.
Note: The length or end date of your service subscription does not change if you do not allow sharing of information.
This navigation system uses a GSM network (the embedded sim card) that contains location information about your navigation system. By law, the network operator may be required to retain this location and other information for law enforcement purposes and TomTom has no influence over this. If you disable information sharing, the mobile network connection is not active and the network operator cannot store location information".
If you think that your information is not being used for the purpose for which you have provided it to TomTom, contact us at http://tomtom.com/support

I'm going to keep my LIVE services active - the HD traffic is the reason I purchased and there's nothing to touch it on the market. It has really helped me out many times.
I'm more than happy to share my information.
What I'd like is an option to answer "yes" once and for all, so that I don't have yet another button to click every single time I fire up my TomTom. I guess the reponse would be that it's better to ensure my consent each and every time, and it would be difficult to manage reinstating the question if anything changed that required fresh consent. 
HOWEVER from a functional stand point it has the following negative effects. First of all The way Maximum speed used to be displayed was below the Current Speed using same size and color font. This was a Perfect combination to glance at, make the mental analysis of current vs posted speed. Both numbers were offset only slightly vertically in the same column of sight. However Now the Maximum Speed is displayed 1/2" or more to the left in a different column or vertical plane of sight and the current speed is in another column to the right. Its simply not natural for eye's to have to glance right and left to compare a changing value in one column to a fixed number in another. The way Maximum Speed was displayed in the prior update was much easier on the eyes and to process the difference of speed. The second negative consequence is the fact this new Speed Limit sign is black lettering on a white background. I do most of my driving at night and have selected the darkest color combination settings. But now with the new Speed Limit sign icon, there is significantly more concentrated WHITE LIGHT coming from the display. Seriously, it's noticeable..!!!! and in a reduced light environment the extra sq inch of the new WHITE speed limit icon is a real distraction compared to the much less sq inch of just white lettering on black background as before. This should be an easy fix to make. Just make a logic branch under display Maximum Speed in the Status Bar option in the Settings area. In a future improved update possibly a user could choose: Settings / Status Bar / Display Maximum Speed / 1) Display as Speed Limit sign icon or 2) Display below current speed (no icon). TomTom already has the programing code for the new and old way of displaying Maximum Speed. If anyone else agrees, then Please Reply to this post. Hope someone from TOMTOM is looking or listening... ))))))))) TomTom is still awesome, though a little less awesome to me with the new Maximum Speed limit icon... 
Thanks in advance... Happy trails to all...!!!!
