But if the tomtom misregisters the speed limit, ie the A3 heading towards Kingston where it thinks the dual carriageway is a 30mph limit, it makes it impossible to set the cruise control accurately to 50mph as you cant read the GPS speed.

Clearly the issue should be that it should be optional. Personally I am capable of reading numbers on roadsigns so I know fine well what the speed limit is, I don't need TomTom to tell me about it, and more often than not get it completely wrong.

Most of the time when driving on fast roads I can't see the gps speed I'm doing because it's constantly flashing.. and TomTom saying you can just turn the speed off is of no use at all.

If they want to put an overspeed feature just put a red box around the current speed, even if it was just red text it wouldn't be so bad, it's the flashing which means whenever you look at the speed... it's not there!

Regarding the speed and speed limit display, it is inaccurate in many cases. Personally I prefer just to see the speed. To only give the option of "all or nothing" is poor. It would be far better to have the option to keep the old speed display or if it has to be, why can't the colour simply be flashing Yellow or something like?

Right, straying back on topic....what we need is a patch to disable the speed check. A couple of no-ops inserted at the right place in the executable would fix this annoyance.

A few questions to get us started:

1. Anyone know what processor is used?
2. Is there a dissasembler available for this processor which runs on a PC?
3. Is the TomTom applicaton resident in ROM or loaded from a storage device?

Either that or a patch to remove the speed limit data from the map files. I wonder if the speed limit data are held in a separate file?

WHY add a function like this when so many roads has got the wrong speed in the database.

WHY use RED color against a blue backround as a warning. Impossible for me to see and 7-8% of the male population are color blind (Hard to tell the differens in the red /green spectrum) (Tried it on a friend and he doesn't see the numbers at all!!!)

When Tomtom has grown they must have employed a lot of incompetent people.

I have mailed to Tomtom about this and some other issues and all I get is standard replies.

Who the xxxx do they listen to if not their customers????

Has anyone made progress with this yet? I'm also colour blind, and can't see red against the blue background.

Would it do anything if we deleted TomTom's speed camera database?

No, the data for the speed limits is part of the map data.
It definitely needs a change in the operating software, which will only happen if TomTom themselves get enough complaints about it.
If anyone out there doesn't like it, please tell them so!

Inserting NOOPs (A NO OPeration is an instruction executed by a processor, that doesn't actually do anything other than occupy a single clock cycle. Therefore replacing a call to a subroutine by a series of NOOP instructions causes the program to in effect, to ignore what previously would have called a subroutine etc.)

It may work, or even an RTS at the right place. It depends if the OS does a checksum before it starts.

The OS is Linux I believe. Clever little device really, shame the TomTom application is so Shonky. Now, if only the TomTom software were Open Source too.

Happy to have a hack myself. Just need a hex editor and a memory address range. Must be able to decompile the code, depends how clever TomTom has been with pre-execution segment.
