for 6210i nokia phone

the phone turned off the radio when in use (muted) - I think it has a speaker of its own - as it does not come via the radio speakers, and MESSAGE appeared on the info display on the car

Anyway , today - it started to make a clicking noise and kept turning the radio and info unit on with MESSAGE on the screen.
I have removed fuse 34 - which does the info display and the radio

Any idea of a wiring diagram for the car kit - so i can start to diagnose where the fault maybe
I took the front control unit off the radio and it still switched the display on and made a clicking noise

my wife thinks she forced the glove compartment closed today which may have caused it

So then the next questions are

how do i get the radio out - from what i have read its a couple of screws in the 4 holes and then once removed - using a metal lever to remove - hoping to make up a couple of wire coat hangers to do that
Am i correct
next i think there's just a screw that holds the radio case into the dashboard and so that comes out so i can get to the wiring

also how do i get the glove compartment out so i can get to the cables that run down the passenger side

With the wiring - I dont know if they have cabled into the exiting loom and if i can then remake the connections - i guess solder and heat shrink
but without a wiring diagram I'm not sure

thanks for any help
