GT4 said:5) PCM button de-gunk
The main PCM dials/buttons for volume and scan/scale etc are rubberised, but over time finger acids etc dissolve the rubber leaving a gluey substance.
Simply pry away (volume just came off with finger pressure, scan button required the assistance of a plastic plectrum to lever off)
IPA was recommended, but it was still hard work.
So I tried some of Alex Yates' patented WD-40 tonic, and it wiped straight off.
I simply cleaned off the excess WD-40 with a baby wipe and popped buttons back on.

Use a credit card or other plastic lever when pulling if it is a bit seized.
WD-40 neat.
Allow time to sink in/soften (you can still agitate, and that would be advantageous, but just be prepared for minimal apparent effect for the first few minute or so, then its starts dissolving/peeling off)
Use an "abrasive" cloth to pull at softening rubber (not literally abrasive, but a rough knit dish cloth or microfibre cloth, rather than a smooth textured cloth)

Thanks GT4, I'll give it a go :thumb:
GT4 said:Have you got down to smooth solid plastic yet?
The rubber is just a surface finish.
Even if the underlying plastic button is discoloured, just respray with satin black paint or rubberised paint.

If you can't renovate, I'd be on the look out here or eBay etc for a replacement HU available due to upgrade (fascia looks a little tired, if you don't mind me saying)
I bought a new looking CDR32 for £100 (had to travel to Norfolk, mind)
.. or a lovely new(er) Becker Nav/MP3/BlueTooth/iPod etc enabled HU
