Traffic not working at peak times

While I'm not certain it is related (to the WNRO update), you may wish to check out a couple of other possibilities.
Yes, the recent WNRO update will ensure the time (on the GPS device) is properly displayed (after getting the satellite signals).
Find out if the software in your GPS device (model, etc.) can be updated (via the tomtom HOME software). If it can, and if the WNRO update is the cause of your not being able to connect, it may solve the problem.
If the software cannot be updated, it's TomTom's way of phasing out (i.e. not continuing to support ) older models of their GPS devices ... and tomtom hopes you'll get a new model, etc.
Otherwise, try to update the "satellite location" information regularly, i.e. the QuickGPSfix (data) patch, using the tomtom HOME software. It provides updated information to the GPS device on the (new) locations of the satellites. [ Yes, satellites do stray from their locations ] That may solve your problem too.

You will know if your (specific) unit comes with a free life-time map update if it says so on the retail box that it comes in. Usually there is an "M" ... indicating free Map updates. A "T" indicates free Traffic (info) updates.
Otherwise, you can register the unit (on the TomTom website), and use the TomTom HOME software .... to find out. When you connect the unit to your computer running the TT HOME software, it will automatically tell you if/when you have updates ... including any free map updates

TomTom recommends that youvisit their website to find the approved car chargers. There is a reason for that. The devices that have Lifetime Traffic update use the charger chord as an antenna to receive the traffic information.
If you are willing to lose that capability then things are simpler. Check the cable terminal that goes in the device. The end is one of two types USB mini B or USB micro B. Any car charger that has the correct end will do. But you lose the traffic updates.

I'm using the TomTom Go 730T - I think this is the latest and the last TT with Traffic because TT stopped supplying this option. I'm having the same problem from time to time but a reset helps. Just press the Reset button and after restarting the traffic option is back. Janos

started to work again with no intervention. This seems a service fault!

tomtom is coming out with software soon to be able to use your g1 as a gps device. theres apps on the market that let you view traffic updates just look up gps on the apps market and find one there. i believe google maps does traffic updates. you should get the docking station for your car it replaces expensive gps devices.

That means you didn't let TomTom Home finish your update before you disconnected. You can do one of two things: reconnect update your device, but if that fails to work, you're going to need to do a hard reset of the device. It is very important to allow TomTom Home to completely finish installing any updates you select before disconnecting or the software may become corrupt.

Hi, If its all working OK to your requirements . Let sleeping dogs lay. Theres no need to update it if you are happy. If you require traffic information updates ( thats if you are paying a subscription for the service ) then you will probably want to update anyway..... You can update by going to the TomTom website and downloading their software "TomTom Home" . Install this to your PC and follow the instructions . You will need to connect your TomTom to your PC via USB cable in order for any updates to take place. TomTom Home does this automaticly for you ( more or less ). You should laos have received a CD with your TomTom at purchase and this CD contains the TomTom Home software . Good Luck.

I phoned tomtom help line, they sent me a download by email which i ran on the tomtom which wipes the flash memory clean. Then did a download of latest tomtom operating system form tomtom Home software. When i tried to setup wireless data connection i couldnt believe how quick and easy it done it and now works amazing fast to find traffic updates in secs !! They told me that if you have used the tomtom with a few phones and changed a lot of settings the flash memory gets full and thats what made it stuggle to connect and was slow. Im so pleased it was driving me mad !! Hope you resolve urs the same. The number is 08451610009 Darren.

The problem seemed to be solved when I downloaded the latest update onto my TomTom. Although it was not as the RDS-TMC Traffic Reciever information stated on the box supplied with the system, I was able the recieve a signal form a radio station.

I have been unable to prove the whole system as I have not encounted any traffic holdups to date.

Thankyou for your reply.

Yours Faithfully
