Audio systems for trikes

[Wallace]

got a Sony RM X55M Audio system on the trike, thought it only had a radio on it but it started playing a cd today.
Ive not got a clue where the CD player is located on the boom, it has to be accessible but can't see a thing, does anyone have one and if so where is theirs located.

thanks in advance
