Feeling chuffed.
Replaced the nipple thingy on my Garmin eTrex with one purchased from Russia. This caused me to decide to have a go at my Kindle Keyboard, that has languished on my desk with a broken screen. Superb instructions on dismantling and fitting! Curiously there was a screw in a hole where it shoudna been. I rather suspect someone has had the back off already. Only problem was that a little pad designed to ensure the screen plug doesn't come out had rotted and was not usable. Double sided tape & foam did the job.
