Need Broken Mio Digiwalker C220 for Parts !!!!

[jediphx]

ok I feel stupid as I am notmally very technically savy but I took the back off of my C220 GPS yesterday to enlarge the speaker holes in the back. I have done this a few times with no problems but this time when i put the back on the power button does not turn the unit on. I cannot find a picture of the insides of a C220 to see if and what piece obviously fell out that is not allowing the power button to turn the unit on. Im hoping someone can help me or maybe has a broken unit that I could use power switch parts from. Thanks in advance.

i have a c520 that im about to send back to get a new screen. if youd like it instead you can make an offer, otherwise i can tell you exactly whats wrong. the button on the case of the 520 pushes on a little metal disk that is held on only by tape. if you try and line up the connectors on bottom then push the top in it will push this tape and disk off to the side. this little silver disk needs to sit centered on the copper rings on the circuit board it sits on. its this disk that when depressed makes contact with the inner and outter circles on the board, giving the unit the command to power on and off. i can take a picture if it will help in the next day or so but ill be sending the unit in on monday to mio.
