I'm looking at a Clarion CRN 28 with a dim display - you can barely read it in daylight. I suspect it may be on permanent dim display, because it doesn't get any dimmer when you turn on the lights. I've got a user guide for it, but that doesn't show the wiring connections, presumably there's a feed to the car lights. 
Can anyone throw any light on this please?

                        wack the top off and see if bulbs are user serviceable 
any factor will have the bulbs in stock or maplins 
 
be aware a lot of modern stuff has the bulbs on the minu-te pcb  so you cant mess 
 
no idea what your gramaphone looks like
