Hello everybody,

does anybody came accross hidden features of head units from the
subject? Today I have found that pressing source button + numerical
buttons displays some strange things.
For examle pressing source + 4 displays BL 13.7 on the panel. You can
even change those numbers from 9.7 to 15.
Pressing other key combinations also displays strange things which are
not mentioned in the manual (for example OF 70 of SUM A3DF etc.).

If someone knows what these hidden functions do, please help.
Maybe I'm missing something from my cd features :-)

Hi Nikodem

I am courious too, you can also turn the fan off and on, clear eprom data
(haven't tried that yet...)

Maybe some Alpine Tech can reveal the secrets...
