nope its age. the answer is in the FAQ I wrote.
F0 = guides,gears,loading trays - and that is only the start of it. best solution (though you lot bitch about spending $$) is to rip the lot out and go aftermarket. BOSE is NOT an issue. the 6CD mech is about $900 now and I'm still waiting on one ex japan for a customer (thats been 6 months!)
Now despite what you may think or have been told:
screen can be kept its NOT part of the radio
OEM panel CANNOT be reused unless you are doing a CAR PC or the like and are doing a lot of custom work. (you still need the A/C controller.)
Bose gear (amps and speakers) can be kept with a decent inteface (not the shit off ebay.) and it will work fine and have decent volume.
I do the panel sets for them and have part numbers for all colors of the dash. its as easy as asking me.
