night mode

Hi Ive checked the box to have my TT740 switch to night mode when dark. For some reason the unit is not changing to night/dark mode.

Any ideas how to correct this issue please?

It needs to be connected to the car dock in order for this to work - Mike

Hi Mike,

Thanks for the reply - the 740 was in the car mount. Night mode works if I choose this option manually but appears not to go into night mode when set to do so automatically

What concerns me is even if I place my finger over the light sensor so the unit thinks its completely dark the unit still fails to go into night mode.

Thanks for pointing out you can manually switch between day and night mode - this method works without any issue.

Yes my finger is on the right spot Smile

Last night the room was completely dark, and no auto switch to night mode.

I hope the unit is not faulty - if it is, does this mean I will have to return to Tom tom and be without unit for a couple of weeks? (I purchased my unit from tom tom direct)

I was wondering if anyone else here with a 740 suffers from the same issue?

I can assure you my 940 needed to be on the car mount for this to work, I will look into this again with the latest software on the device. How long did you leave the device with the light sensor covered up, the unit takes quite a while to respond to light level changes to avoid nuisance switching - Mike

I drove home last night from oxford to Marylebone High Street and the unit failed to go into night mode - so a good hours drive

I will leave in the unit in the car mount and cover so there's no light seen by the unit sensor and report back later

I've had this problem on my 540 too. It does go into night view most of the time, but sometimes it doesn't. It seems to coincide with it having been connected to the PC. Strange.

You do have to have it on the car mount too. Usefully TomTom don't mention this is their documentation!

I don't know if this is related but the other night I was in town (small town) with overhead street lights and it was in day mode while I was driving out of town to the country I happend to look at the screen as we were aproching the last light post and the map was in night mode beyond the last light and still in day mode where I was.
Shore enought when I past that light it switched to night mode screen.

Its not unique to the x40 the older x10 series did the same thing, unless they were on the car dock the screen brightness wouldn't vary - Mike

Have placed the unit in the car mount and and set a route - covered the light sensor and its now switching across to night mode - strange it would not change mode last night and was in the car mount.

I will monitor the issue over the next few days

I think Mike is correct the mode does not change unless the unit is in the car mount. Why is this Mike?
