Hey all - my first post, having signed-up today and already made good use of the bulb-changing guide.

Anyway, need a bit of an assist with sticky buttons on my Concert 2 head unit. I'm guessing the previous owner had a coffee or coke spillage from the cup-holder above. Preset buttons 2, 3 and 4 are partially knackered, being 'semi-glued' by drink residue (I assume).

I had the unit out for fitment of an iPod lead - and can easily whip it out again - and I had a cursory look at the front assembly. Can the front be dismantled to allow cleaning of the button mechanisms? Anyone done this?

Appreciate any clues here.
