GO 740 - 860 map installation problem

cibofbs wrote:Dear

I would like help to install 860 map on my go 740 device.
I give a try, and can't success.

My Device (working well, before try):

map 810
bootloader: latest available (I think 5.5.20, didn't have my device at work now) 9.058 bootloader is 5.5259
navcore 9.058

Hardware thing:
I had a 4GB SDHC Card, except internal.dat on internal memory and autorun.inf, all date are exactly the same between internal memory and SD Card.
My computer is Win XP Pro SP3 fully updated, full administrator rights for current user, TTH 2.7.x

Downloaded:
Western and Central Europe 2GB 860.3101
FastActivate 1.8.02
AutoActivate 1.5.02 Premium Not needed

What I do:
* backup internal and SD memory =) OK
* delete map directory on internal memory Not necessary.
* copy new 860 map contents to SD Card map directory Do mean "map folder", rather than "map contents"
* copy FastActivate (also try with AutoActivate with same results) to SD Card (also try it to internal memory) OK You don't mention putting a copy of the 70 ttgo.bif file on the card.
* run FastActivate/AutoActivate to patch map and ttsystem (tth is already patched): all seems correct with a lot of "OK - DCT file exist"
* I disconnect my Tomtom properly with tth

What happend:

* I restart my GO (also try full reboot with "tamtam" sound)
* the start screen appears, two steps of luminosity, then... nothing... endless (except when empty battery)

What I try:

* rename mapsettings in map directory, then restart: nothing NO!!
* try "Operate my GO" from TTH: I had "Innacurate map" message on the screen (red), it give me the choice to choose a map, but of course I only see the only one on the SD card. If I select/validate: nothing
* try to put back the 810 map on the internal memory only: nothing

At which steps does I do a mistake, or what's wrong ?

Thank's for your help

Downunder35m: I will also try the .dct file, and clear flash.

If nothing better, I will retry from scratch (my backup), and try an alternate patcher for TTSYSTEM.

Do you confirm 3101 is the right sub-version for my device ? (GO 740)

Thank's

Back to home, I check the map directory, and found my mistake !
In fact, to preserve my POI and settings, I merge my actual map directory with the new map content, so the directory had 2 files of that kind: "Western_and_Central_Europe_2GB-XX.meta"
One for old map, one for new map.
When using the patch utilities, it looks only the presence of .DCT file in directory, and go ahead if more that one .meta is there.
I remove old .meta, and patch map again: it's working

Thank's a lot for your help and utilities =)
