Just had to replace the battery on my wife's car, and now find the dreaded "enter password" on start up.
Seems the previous user decided she was going to install a password, but didn't think to either write it in her vehicle documents, or tell the dealer she sold it to !!
I've searched this forum for the past couple of day, and managed to get a copy of goldenapple, which allows me into testmode. However that is where I'm stuck. Most of the password recovery posts suggest entering file manager, and finding the security folder on the nand drive, to access a text dump of the password.dat, but this seems to apply to earlier / different models to my unit, or it's a hidden file, as I can't find anything remotely similar on the unit.

I did find one reference to deleting user data in the extdat directory, which I remember seeing whilst searching through the file system.
My question is, do I just delete the user file / folder, or is that likely to screw up the unit. 

I know this has been 'done to death' but I don't want to ruin the unit, by deleting user without asking advice from 'those that know'

Thanks in anticipation

Thanks Bonee. Testkey doesn't seem to work on my unit. At least, none of the versions I've managed to download do.
Goldenapple lets me into the testmode, so I'm guessing that's the same, just a later version of software. 
Will a system reset clear the password thoug? I thought it would just clear any updates and settings, but not the pw.
I'll have another play later (If she lets me. Two days searching has wound her up a little. oops)
