no gps signal

[bd1977]

So, Ive had my TomTom One 3rd ed for about 7 months now and use it everyday for work. Its worked fine untill this morning. It would not locate a valid gps signal. First thing this morning I loaded ver 7.166 and the GPS quick fix, left the device turned on and sitting on my dash board litterally all day while i was working. No luck.

The message says poor GPD signal, it does not find any satellites. I have reset to factory settings, made back up and recover the tomtom and update all via tomtom home. Is my tomtom dead?

no dead tomtom

try a soft reboot stick a papper clip in the little hole in the bottom of
your tomtom:

Try This

Try deleting the contents of your Ephemeris folder on you Computer, then reconnect your tomtom to the home software application. It should sense the files are missing and download a new Quickfix file.

I wonder if there is someway to totally format and reload my tomtom?

ephemeris folder

did you check your tomtom for the ephemeris folder after i install 7.166
it did not ask for quickfix . so i check for this folder there was no ephemeris
folder

ok, i have a ephem folder.... is this different then the ephemeris fold?
i dont have any folders named ephemeris, just one named ephem.

Right and in there should be at least 2 files: lto.dat (satellite data) and ee_meta.txt which contains an entry similar to this: "Expiry=1212557431" where the number corresponds to the number of seconds after Jan 1st 1970 and can be translated into a date by the web site utility found here: http://www.onlineconversion.com/unix_time.htm and translate it to: Wed, 04 Jun 2008 05:30:31 GMT.

Word of caution here is that lto.dat is for ONE models that use the Hammerhead gps chip and not the SirfStarIII chip used by TT GO models.
