TomTom died

Heard of a warranty claim on a different brand refused cos it was left " in the sun". Suppose it would be if it was on the windscreen but I think the instructions advise to keep it below a certain heat and out of direct sunlight. Whilst it mightnt be overly hot outside interior temps can get up to 60 deg C pretty quickly.
We leave our buses in an open yard for about 5 hours during the day and even tho its only 24 -25 outside the aircon can read upwards of 38- 40 even if we leave the door open when we restart them.

Steve,

My Tomtom would not turn on unless it was connected to 12v so I went thru the reset procedure as outlined on the Tomtom website and it worked.
The Tomtom will now power up on its own power.

Maybe if you reset yours it may do the trick.

try starting it up connected to your ac adapter. or even pulling the battery out and putting it back in.

If that fails, check out the brands web site or your dealer, as it may be a known issue.

Same as the guys above.

Mine died and only way to start it was to use a 240 v adaptor. Then reloaded all maps on a new sd card and backed up to be on safe side. Since then it has been going great - touch wood. I only had the problem after installing the later version on the original supplied sd card. Now have later version on a different sd card and no worries. I often wonder if it is from lack of use as mine only gets used infrequently nowadays. good luck

This may help for the future.

I had a cover made from that silver windscreen shade, so that it fits over my Navman for the times I need to leave car locked in the sun .

Hope you get yours fixed as per suggestions above.

Steve, try putting it in the fridge then doing all as suggested, sometimes you need to cool down the display crystals

Steve,
Hope you resolve the problem. Not recommended to leave them in the car. Had a friend who was given a Tom Tom for his birthday. His wife went shopping and left it on the windscreen. When she returned 30 minutes late, broken rear quarter panel window and Tom was missing. On a lighter side, I went to a public toilet with Tom in my pocket (still turned on). Standing there minding my own business when "Ken" tells me "Turn left". Certainly attracted the attention of the guy on my left until I explained the situation.

Steve,

I've got a Tom Tom 500. Had it for 3 years now and occassinaly it dies and won't turn on.
Take it from the cradle turn it upside down and you will see a tiny reset hole in the bottom. Use a pin or similar and press the reset for about 2 seconds and it should reset.
We used ours in Darwin for two years and the heat did not effect it although I did cover it most times with a cloth to keep the direct heat off it. The inside of our car was often 50+ degrees.

The battery does not last long on it's own power now, but they tell me they have to send them to China to fit a new battery so I just run it on 12 volt now.

Happy ending - although a trifle embarrassing. Went back to the shop after trying a couple of gadget repairers who wouldn't touch it for fear of buggering the thing up. Anyway, my hopes sank as the 18(ish)-year old girl said "just try the re-set button", which I'd done about 4/5 times with the thinnest Allen key I could find. She got out a paper clip and poked it - BINGO - back in action. "erm....I tried that a few times" stuttered I" -

she just gave me a sympathetic look.

but I tried the re-set button heaps........aaaaaaaaaaaagh
