510 crashing freezing

[normanji]

after i disconnect my 510 from the PC it crashes and i have to reset it using a pin.
then i have to reconfigure it to the settings i use.

also i cannot get it to password protect.

brief description of what i do

connect usb cable to PC,
sit tom-tom in docking station,
either turn tom-tom on and wait to be asked to connect to PC, or run tom-tom software then turn tom-tom on.

i can install delete and do all the other stuff with the software.
as for setting 4-digit password,
go to my 510 (pc screen), do as the screen says then enter password, then confirm.
turn 510 screen off on the PC then turn tom-tom off by button.
disconnect from docking station then switch on, and thats it.

it either crashes and has to be reset by using a pin, or its been reset itself.


is there anything I'm doing wrong or is my tom-tom faulty.

please help!

thanks in advance
