    Never saw any post about where2. I think if you can not fix it you could use it as spare parts.

    I think you mat be right , it may make a good parts machine. I was able to figure out the 6 digit key ( 1 in a million shot) . all works well until it sees the sky . if you power it off after seeing the sky it locks again and the key no longer works until I unplug the battery.. the where2 firmware doesn,t have all the security icons that the normal 780 normally has. This must have a back door that i doubt I will ever figure out. The only way I could use it would be to leave the battery disconnected.

    You have to unlock it before you be able to play with device. You have only few options to unlock it.The key is four digit. Go to car rental place and rent a same device or get the code from them. You can punch in 0000-9999 numbers to find the code,It may take few days. Wish you good luck. Any body know the location of security file in this device ?

    There is no such thing as a security file on Nuvi. What problem are you trying to solve ?

    If it's a pin lock problem there is no known solutions, send it to garmin.

    If it's a locked map problem the tools discussed here will make any map useable in your 780.

    Did you talk to anyone specific? As you know, this is pretty annoying. It screws up daylight savings time, as well as when the device goes into day/night mode.
    No one specific, just tech support.. No fix as of yet..

    Formatted Nuvi 780

    Hello all, I accidentally formatted my Nuvi 780 drive and now the GPS is stuck in the loop. Could anyone upload their files? They aren't big, as I don't need maps. Just whatever in the Garmin directory. Thanks.

    P.S. From my research, the software for 750, 760, 770 and 780 is identical, so I'd try any of them.

    Anyone? This would mean the world to me, such a small upload! OR, I think I'll be able to update my GPS using the WebUpdater, but I need the file "gamindevice.xml". Anyone could upload at least this file?
