Locked & Unlocked

Hi
After installing the new maps I thought i would try the gimtools and catymags cneig with the tool, after unlocking I found the unit would keep shutting itself off when it got to the garmin screen unless it was in the cradle in the car. I then tried the locked version without gimtools and it works fine with no problems so far, so my question is I thought locked versions would not work in my 2460lt and maps had to be unlocked?. Or am I just misunderstanding this.
Thanks for any explanation.

A locked .img file will not work in your 2460 unless it is the map supplied by Garmin for the unit and has the corresponding .gma and .unl files present. Check the map in GMAPTool to see it's lock status, under Info tab.

Do you mean catymag's upload named cneimg.rar of CN Europe NTU 2014.10 from [Only registered and activated users can see links. ]? Her posted GMAPTool log shows clearly that the image file is locked:

Hi Neil
Yes thats the one I downloaded it , unrared and installed into my satnav as is and it works fine as is, when I used it with gimtools I had the problems, so technically that should not be working in my satnav?.

gimgunlock doesn't change anything in .img if the map is already unlocked.
I rarely post unlocked .IMGs, and I can confirm .img in my archive is locked.

I wonder why it works in mine?, I will copy it from the satnav and run gmap, maybe I got lucky?.

You can run it from nuvi, right click open with GmapTool. Details tag.

updated unit to 3.40 software and now it wont work lol says cannot unlock maps, reloading with the cneimg. file that has been gingtools to see if it will work.
Update: used the tool again and the unit keeps switching off like the last time, will only turn on and stay on in the cradle.
Update 2: windows file repair and hard reset and all seems well, I restarted it 6 times and it seems ok now, phew.
Still don't understand why a locked file worked in the fist place.

Definitely not normal behavour for your unit. From memory, the only time a locked map will work in a particular unit without the necessary gma/unl files is if they have been present and operating alongside an 'official' map originally, but they then are removed in mass storage mode. If the unit is not hard reset afterwards it will continue to read the map normally, but will not recognise it after a hard reset/clear NV memory. I think that's correct and there is no other way a unit can recognise a locked map without those original files corresponding to the unit.
