The clock shows 0.00am
The clock displays 0.00am, and when you reset it after a few seconds it goes back to 0.00am. Ive done a reset to factory settings but no help…!! Any ideas please?
A GPS navigation device with a large touchscreen. TomTom’s all-in-one GPS navigation devices all include a touch screen, speaker, USB port, and an internal Lithium-ion battery.
Hi, I have a 430XL with very similar problem. On mine, the clock “works” in that you can set it, and if you power-off and then power it back on, it retains the time across the power cycle. HOWEVER, after a few minutes of its being ON (maybe until it locks on the satellites?) the clock resets to 0:00 just like yours.
This just started happening a few days ago. I *strongly think* it’s related to the “epoch rollover” of the GPS system ( https://arstechnica.com/information-tech... ). If so, and it doesn’t clear up in a few days, it’s probably permanent :-(
My unit otherwise works fine. The time is always 12:00AM, but the “arrival time” is still the correct # of minutes from that, and the map/navi functions are all as usual.
I could be wrong too, but this just started happening a few days ago…so seems related. (sadly!)…
Does the clock work OK when the charger is connected to the unit? You didn’t specify.
If it does and it doesn’t work when on battery only I’m wondering if the battery is failing and needs to be replaced.
How old is the unit?
Even rechargeable batteries have a lifespan.
Here’s a link to the ifixit TomTom XL Battery Replacement guide which maybe of some help.
Replacement batteries are available online.
Just search for 6027A0090721 to get results for suppliers.
Here’s a link to just one supplier. It it shown only to give an idea of the cost of the part. There are other suppliers online that may suit you better.
My answer is that i love my tom tom. It actually may be between 10 and 20 years old. Just the other day i left it in a hot car and on, and i started having problems. Map wouldn’t come up, couldn’t find GPS ,clock wasn’t working. I reset to factory while charging. Successfully lost all my info. Repeated attempts to sync the clock but would only last a couple of seconds then back to 12am. Everything else seems to work other than it also wont let me keep same vehicle and the battery is constantly charging and never attaining a full charge. My suggestion is plug it in for a couple of hours. Don’t use it during the charging and try again in a week. I think it will work. One other thing; when i used to turn it on it would chime. Now it only does it when i hold the button for 15 seconds. Then it brings ne to the “i agree” screen and my current position appears. Go figure. Todays date 7/21/19
