maybe this is more a electronic problem than software but i am looking for
some suggestions.
i got a tomtom go 720 for over 2 years now and untill recently no problems.
I always leave it in the car ready to use but for the last few weeks i
havent used it and its been really freezing here since.
When i tried to start it up again i only got the tomtom logo and after a
few minutes a sign with a cross over wich i assume means no memory or
software.
at first i didnt panic since i got a recent backup.
Connecting it to the computer tomtom home doesnt start or recognise the
device when started up manually.
Using windows explorer it recognizes 2 external devices both with none or
no accesible memory .
I am afraid i got a total loss here .Further more i have no idea what the
reason could be except for the freezing tempuratures.
Any tips anyone? thanks

Device specs often list different temperature ranges for storage and
for operation. I had always assumed that storage wasn't that important.
Maybe I was wrong, and maybe your device went below the allowed range.

Thinking about it, I'd guess that if it got cold enough, the battery
could literally freeze and thus be ruined. Maybe electrolytic
capacitors too.

I'm just guessing, so maybe someone here who knows will post real info.

Doesnt happen with Lithium Ion batterys.

Doesnt happen with those either.

Thats obvious.

Wouldnt dream of it.

I have just had a look at the Users' Manual for my GO 910 purchased in
September, 2006. At page 73 it is stated, inter-alia with regard to the
battery :-

Temperatures : Standard operation : - 10C to + 55C ; short period storage
: - 20C to + 60C ; long period storage : - 20C to +25C

I am sorry I cannot offer advice as to remedial action.

Have you tried leaving it on charge for (at least) two hours before turning
it on? TT: Battery lithium-polymer (up to 5 hours operation)
Starting a car may generate voltage fluctuations, with the TT already turned
on starting may be a cause
Have you tried booting from an SD/MMC backup via the "SD card socket
compatible with SD and MMC cards "

No one has suggested yet that you press the reset button. My 730 has one on
the bottom edge near the centre.

i am sure its not the batterys since i can keep the logo on the screen for
ages.
However maybe its worth a try to put my backup on a sd card and see what
happens

I would try that too. If successfull, I then would try to reformat internal
memory and reinstall the whole stuff on it ... then pray.

Btw GOx20 are well known to suffer from fragile internal memory. This is not
really an issue as you might still use SD-HC (up to 16Gb) to run TomTom
(even if internal memory is dead).

Rgds.
