FINALY THE ANSWER OF MP3
I got in to contact with a tech. in the Fiat Magneti Marelli (the people who make the Connect system) and he sent me an email explaining about mp3... here it is:
The Connect system can be updated by your car dealer if and when a release
with relevant improvements is issued.
For the time being, and limiting myself to FINMEK Magneti Marelli products,
new releases have been issued for the Connect Nav+ of FIAT Stilo and Alfa
They are (or soon will be) available to car dealers for possible updating of
existing cars, while newly produced vehicles of course come with the latest
Regarding MP3, the first Connect Nav+ designed (i.e. Alfa Romeo 147, FIAT
DoblÚ and Ducato) used an internal hardware which could not support it (and
therefore will not support it even with a SW upgrade).
Following models feature an improved internal design which allows for MP3
decoding; this is thus available on all Connects for FIAT Stilo and on the
latest Connect Nav (without the "+", meaning it has not a colour display but
a smaller monochrome one) which is going to be available on Alfa147, DoblÚ
and Ducato, too.

WELL!!!! it looks like the 147 CAN NOT PLAY MP3.... due to hardware limitations.
So here is the answer finaly!!! People who want to play in there alfa147 are just going have to wait until the new Connect systems are instaled.
