Apologies if this is a dumb question (I did try searching and couldn't find any clues) - but how do you remove the radio?! It's an original-looking Radiomobile unit mounted in the trapezoid face plate, however I can't see any obvious screws or fasteners... The radio itself works, but the tuning is stuck (issue "feels" mechanical rather than electrical) and I want to open it up and take a look. Maybe try and add an aux-in if I can. But first I need to be able to get the radio out of the car! Again, sorry if this should be obvious, but I don't want to be hamfisted and accidentally break some irreplaceable bit of trim or some such... Cheers!
