How I repaired my Garmin: electronics for dummies

OK, so yesterday my Garmin died... first did not want to connect to a computer, then it won't even switch on anymore. For a 6 years old unit, that should be the end, right?
Wrong... armed with determination, I went to Maplin and got a set of mini tools (7.99), this.

including the crucial Torx T5, that unlocks the 4 bolts that allow you to open the device. Once open, you can flip the screen and reveal the mother board. I understand zero about electronics and inside all did seem well

I flicked the black plastic retainer to remove the screen, then I refitted the screen and magically the device decided to work again. Somehow the contact must have been lost. In flipping the retainer back, I managed to remove it and it proved impossible to re-fit, probably just as well, as clearly it is the culprit, not doing a good enough job in keeping the contacts together.
So I re-fitted the screws that hold the mother board in place in such a way that they hold the screen contacts in place too, closed everything and ta dah... it all works like new. Went for a 100 km ride and all is well.

Moral: don't give up on your broken GPS... go to Maplin instead!

Desperate times... there has to be a way to open it

Rule #42 // A bike race shall never be preceded with a swim and/or followed by a run.
Now working like new, echoing Ugo.. don't give up, give it a go!
I don't have one to play with but, I would imagine its similar to modern phones its all snap fit. No idea where to start on stripping one down.
