JUST GO INTO SECURITY SETTINGS AND DELETE THE CACHE FILES FROM IT

This was is a known bug to TomTom. The suggested solution is to update to the newest software version. The Download Page Here is where you can get the newest version.

(2) Backup your navigation device by clicking Backup and restore in HOME
(3) Make sure you have enough space on your memory card or internal memory.
(4) Transfer your favourites to your new map

Downloading and installing your map
(5) Select your navigation device:

• GO x50, GO x40, GO x30, GO x20, GOx10, GO classic
  XXL, XL, Start, ONE
  Rider
  Blue & Me, Carminat TomTom, ECLIPSE, TOYOTA

Before you disconnect
(6) If you have a speed camera subscription, install your TomTom speed cameras.

Select your new map

(7) If you have more than one map installed on your device, select the new map. On your navigation device, tap Manage maps in the Preferences menu and then tap Switch map.

Bring it back into the house (unless you have your software on a laptop) Plug it into the computer with the cable they gave you, then go to Tom Tom's website and follow the instructions for a reset.

Sometimes just plugging it into the computer will automatically reload the software menu.

I have the same problem. It seems to only happen sometimes after I disconnect it from my PC. I find holding the power down for 10 seconds fixes it. It is annoying as it will happen again. I would think it was a software issue but seeing as you are the only other person online that suffers from it - I am thinking it is a defect.

This can happen on rare occasions in very built up areas. Most certainly it can happen indoors.

Using tom tom home from your computer plug your device in and tell it to update. most can now accept the gpsquick fix which will allow tom toms to pick up sats a little quicker

Its not uncommon for some GPS to take a while to "warm up"

Check the tom tom site as some tom toms have a quick sat finder update. If you use tom tom home on your computer it usually has an UPDATE option where it will go online and get any fixes etc for your device.

Even then you may still see over a minute or so to boot up.

My tomtom one screen kept showing that it was waiting for a valid gps signal all day yesterday 7/1/09 what can I do to fix this problem?

plug in the usb to pc (computer)
download tom-tom home 2.6
create an account click update my device/one/go
cllick install gps quick fix

I suddenly lost the GPS signal today and could not get it back. All I got was the "No valid GPS signal". My solution was to tap on the GPS satellite bars when in the route map. this brought up the "Status summary page of the TOMTOM.

I then again tapped the satellite bar which brought up the "GPS Status" page. I then tapped the bar labeled "configure".

The radio button next to the option titled "Minutes (dm.m') was selected. I then moved the selection to "Degrees (d.d) and it started working.

I had just downloaded the GPS fix 5 days ago so it is not like this suddenly caused it to stop working.

This may not work for everyone but this is what it took to get mine working.

Cheers

I have had my GPS( TOmTOM One) on Waiting for Signal for 2 weeks now and I finally fixed it.

My symptomtoms (word play) were no signal at open areas, when connected to Tom Tom Home it showed exactly where I was and worked through the PC but when disconnected back to the same thing.

I called Tom Tom CS and nothing, FLash did nothing, factory defaults nothing, and updating did nothing.

What I did:
I charged the unit completely.
I took a paperclip and while off pressed on the reset button at the bottom by SD slot. I held it there for 30 mississippi's.
I did not turn it on after letting go.
I went outside to my car (parked on roof of parking lot) turned it on and set it on my dash vertically.
I left and came back in 1 hour and wallaaaaa. It is working perfectly!

Let me know if this fixes it.
