The pesky message "Your Maps Are Out Of Date"

[Tiger]

A question.... llooking for an answer.

After updating internal maps (gmapprom.img) on some units you still get these occasional messages that your maps are more than a year old and visit Garmin... etc for update.

Does anyone know what triggers this message or how to prevent this nag message from recurring?

Thanks!

Yes... I too get this quite regularly on my nuvi 765 and would be grateful for any help... TIA

There is some bit in IMG file which makes a Garmin device save the current date and the map FID in NV memory when it first sees the map. In one year this record will make the device show the message (only when the map is loaded) with period ~1 month until a never map version is installed in some special way (I don't understand it yet).
So you can do the following:
1) Clear the record (install date, FID) from NV memory using a special USB command. I can help you with that, but the problem will appear the next year, as you are still using the map with that bloody bit.
2) Clear the special bit in IMG file. I can't do it now.
3) Clear the entire NV memory. You can do it yourself but you will loose many devices settings and the device version (765 will show 7xx at startup).

I had this issue but I don't know how to fix it. What I did was to take the device back to where I bought it and they had some expert to fix it.

The prompt was caused by internal software versions.
Frequently most people update their maps but not the device software.
Conflict on date issues. Does not cause any navigational problems.

This utility should help: https://dl.dropbox.com/u/32785663/mupd-clr.rar
Use it as follows:
1) Fully boot your device.
2) Press the battery icon until an engineering menu appears
3) Connect the device to PC
4) run start.bat by double clicking it

In case of success the utility will print a text similar to the following:

M:\WORK\GARMIN\[UTILS]\mupd-clr\Release>mupd-clr.exe
map update message remover v0.1 by kunix
Initializing USB...
hwid = 596
swvr = 490
name = n№vi 670 Software Version 4.90

Initializing USB once again...
removing the map update message...
all done

M:\WORK\GARMIN\[UTILS]\mupd-clr\Release>pause
Press any key to continue . . .

And if you are lucky the pesky message won't appear sooner than one year from today.

Worth a try.
